to a lesser extent, to the caldphile vegetation of the Cantabrian Mrs. The second, halochasmophytic group is closely related m cliff vegetatiorl found on the southern Atlantic coast of Europe, for example in Britain, Ireland and Cornwall (FERN~'q'DEZ PRIETO and LOIDI 1984) and especially to that found on the Cantabrian coast. However, the vegetation of the western cllf~ of Galicia is already more closely related to that of the Portuguese coast.

The rupicolous vegetation has been partially studied in various phytosociological works, among which those of BELLOT (1951a, b, 1966), C.ASASEC.A (1959), RIVAS-MART~EZ (1969), FERNANDEZ PRmTO (1983), F'F.RNAN~EZ PRIMO and I.OIDI (1984), J. G u m ~ (1984), Og'nz (1986), F E ~ E Z PRmTO et al. (1986), IZCO and Og'nz (1987), F E g N A N D E Z - ~ et al. (1987), P. G u m ~ (1989) and I~REz-C.ARRO et al. (1989) should be mentioned.

In this paper we present a synopsis of the mpicolous vegetation of Galicia, whichis the result of field Work carried out by the authors over the last few years and based on a synthesis of data from the previous studies. The recognized communities are classified in a syntaxonomic synopsis.

MATERIAL AND METHODS

STUDY AgEA

The study region covers an area of 29,439 kin2 and is situated in the northwest of the Iberian Peninsula, in Spain (Fig. 1).

F'~ I. Location of Galicia in the Iberian Peninsula

Following the classification of ALLLr~ (1966), climate is largely European Atlantic becoming subbnmid Mediterranean with a Central European tendency in the east of the region ( ~ , , ~mA et al. 1983). Following the classification of RIV~S-MARTI~Z (1987), six principal bioclimatic belts are distinguished in the region: Colline (with a very characteristic Thermocolline Subbelt), Montane and Subalpine belts in the area pertaining to the Eurosiberian region, and Meso-, Supra-, and Oromediterranean belts in the area corresponding to the Mediterranean region (Fig. 2). These belts are defined by annual average temperature (T), average minimum temperature of the coldest month (m), average

maximum temperature of the coldest month (M), and heat index [ltffi (T+m+M)xl0] (RIVAS-MAR~Z, op. cit.). Annual rainfall, which is high in most of the region despite an appredable summer drought, determines an ombroclimate which varies from the hyperhumid to humid becoming subhumid in the Southeast.

Both biogeographical regions of continental Europe occur in Galicia: the Eurosiberian region (most of Galicia) and the Mediterranean region (a considerable area in the Southeast). Both regions have been subdivided by R_rVAS-MARTI~Z (1987) into Provinces, sectors, and subsectors. Those referring to Galicia are shown in Fig. 3.

The relief of the studied region is very uneven with a continuous succession of hills and valleys. The highest altitude is that of lena Trevinca Sur (2,124 m) but most of the areas are of low (around 400 m) or medium altitude (800-1,000 m) except on the eastern border of the region. The predominant substrata are of an acidic type, especially granites, gneissic schists and clay schists with a acid or neutral pH. Limestone, gabbro, metabasic and ultrabasic siliceous rocks also occur over smaller areas. This last type includes serpentine rocks which have a high level of heavy metals and harbour a very peculiar type of vegetation.

PHYIDSOCIOI.OGICAL INVESTIGATIONS

For the study of the rupicolous vegetation of Galicia, we have followed the method of the Zfirich-Montpelller School (BRAUN-BLANOUET 1964). The syntaxonomic nomenclature followed is, for the most part, that proposed by DIAz-Go~.~J.~z (1989). For the description of new syntaxa, corrections, etc. the "Code of Pbytosociological Nomenclature" ( B ~ et el. 1986) has been followed.

The nomenclature of the taxa present in the relev6s is in accordance with that of Flora Europaea (TurIN et el. 1964-1980) or (in the case of taxa included in the voluraes published to date) the Flora Iberica (CAsTROV~O et al. 1986-1990), with the: exception of the following: Adenocarpus complicatus (L) GAY subsp./a/nz//CAS'~OVIE~O, Agrost/s t//en/NIETO F~Ia~R et ~ s m o v ~ o , Agrost/s truncatu/a PAre. subsp, dur/ad (Bo~s. et REtrma ex WllJ.x.)

RESULTS

ECOLOGY AND BIOGEOGRAPHY OF THE GALICIAIq RUPICOLOUS COMMUNITIES

The principal ecological conditions which influence the florisfic composition and distribution of the studied communities and their biogeographic and bioclimatic characteristics are presented in Tabs. 1 and 2. The first two associations in the Tab. 1 are identical with respect to the four ecological characteristics considered, but are clearly distinct in biogeographical affinities (Tab. 2). Ca/endu~Par/etat/emm juda/cae, occurring in the nitrogen-rich soils typical of seabird nesting colonies, is clearly differentiated from the other syntax& Patietatietum judaicae, ~mbalario-Trachelietum caendei and the Pob~onum cap/tatum community again share the four ecological characteristics, and all occur in the

Page 7: Synopsis of the rupicolous vegetation of Galicia (North-western Iberian Peninsula)

OI~'IZ AND RODP-JGUEZ=O~ SYNOPSIS OF THE RUPICOLOUS VEGETATION 21

Thermocolline Subbelt of the Mineasian subsector. The differences between them axe solely floristic. In isolated areas in the North of the subsector, L3ymba/ar/o-Trache//etum caende/is constituted by the largely Mediterranean and calcicolous taxon Trache//um caendeum L ; in the extreme Southwest of Galicia, Potygonum cap/tatum D. DoN, a neophyte of Himalayan origin, enters assemblage of Parietarietum j:~__~__'_cae species constituting the Polygonum cap/tatum comm~mity.

The next four associations are not differentiated by the four ecological characteristics given in Tab. 1, but clearly have different geographical distributions. The same applies m P/ug, na/o-Rum/cetwn /ndurat/ and Se.samo/do-Ananh/nenmz dur/m/m', which both occur on embankments and rocky slopes or on consolidated bare rock, almost always in wide soil-fiUed crevices.

The next three associations in the table are identical in terms of the characters shown in the two tables, but they differ in other ecological features. Whilst all of them are calcicolous, Pe~rocoptidetwn grandiflorae generally colonizes rock ledges, Saz/fragetum tr/furcatae narrow crevices, and Asplenio-Cheilanthetum acrosticae wide soft-filled crevices in the warmer areas of Galicia.

Cheilantho-Asplenietum corunnense is the only community to occur on ulU'abasic consolidated rocks. The next four associations occur on screes in siliceous areas; they display some biogeographical differences, but they differ mainly in their preference for rock size. Cryptogrammo-Dryoptetideaan abbreviatae occurs in sites characterized by large quartz blocks, Sesamoido-Silenetum gayanae on screes comprised of small fragments of slate, and the Rumez suffnaicosus community and Cryptogtwnmo-Silenetwn gayanae in areas of medium-size blocks of either quartz or slate. The latter community generally occurs in soils with higher moisture levels than those colonized by the community of Rumex su09ut/cosus.

Finally, the Rum~ scutatus subsp, gallaecicus community, is clearly differentiated from the other syntaxa by being limited to metabasic sites.

DESCRII~ON OFTHE NEW SYNTAXA AND COMMENTS TO THE SYNTAXONOMIC SYNOPSIS

The synoptic table (Tab. 3), representing 185 relev6s, summarizes the floristic composition of the associations of the Galician rupicolous communities. It can be seen that, in general, the differences between the characteristic species combinations of the associations included in the synopsis are sufficient to be of diagnostic value. Equally well defined are the three phytosociological classes included in the synopsis: the rocky shore halophytic communities of Asteretea tr/po///, and the non-littoral communities of Asp/en/etea tr/choman/s (on consolidated substrates) and Thlaspietea rotundifolii (on mobile substrates). Within Asplenietea trichomanis there is clear floristic divergence between the calcicolous associations of the order Potentilletalia cau/e.scent/s and the remaining orders of the class. In the case of these latter it is apparent that the taxa normally considered as characteristic do not serve to differentiate dearly between them. With reference to the syntaxonomic synopsis we will here comment only upon new syntaxa, proposed corrections to existing syntaxa and syntaxa which have not yet been comprehensively described.

The association Crithmo-Annetietum pubigerae is found on the cliff~ of the whole western side of Galicia and a large part of the northern coast, areas which have mainly gneissic-granite substratum. However, in the small quartzitic outcrops which occur within its area of distribution, it is differentiated by the presence of Limonium binervosum (G.E. SM.) SAX~ON, thUS defining a subassociation limited to this type of rock (P. G t n T t ~ 1989). Quartz becomes dominant in the extreme Northeast; on slate substrates, the other dominant rock of the Northeast, this association is replaced by the Spergulario-Annetiemm depilatae.

The communities described as Cryptogrammo-Saxifragetum spathularidis F. PRIeTO, J. G u m ~ et AM1c, o 1986 from similar habitats in the subalpine belt of the Serra dos Ancares, appear to correspond to very impoverished units of Murbeckiello-Spergulaum pourretii sax/fragetosum spathu/mid/s. Two taxa which characterize this association, and which give i t i ts name, are not present in the Cryptogrammo-Saxifragetwn spath,_d_midis, so we reject the previously proposed poss~ility (ORTIZ op.cit.) of combining it at the subassociation level with Murbeckiello- Spergdarw: powrefii.

It shows affinities with the endemic association Saxifrago-Murbeckielleatm henninii Bit.- Bt., P. SILVA, ROZEmA et Forrms corr. RIVAS-MARTIiqBZ 1981 of the Serra da Estrela (Portugal), characterized both by its partially endemic floristic composition and by another subspecies of MurbeckieUa boryi: M. boryi (BoISS)." Ro'rriM. subsp, herrmh//RIVAS-MARTIrCEZ, whose populations, although showing some deviation from the type subspecies, have not been considered sufficiently differentiated by some authors (FmmAm)ES 1950) to have taxonomic independence.

The new subassoeiatiom are found in the Oromediterranean or Subalpine belts of the high siliceous mountains of the Orensano-Sanabriensian sector and east of the Orocantabrian Province.

The second subassoc/ation develops in very humid fissures and on ledges of the quartz and slate crags situated above 1,900 m in the Macizo de Pena Trevinca, placed in the Oromediterranean belt. It is distinguished from the other suhassodation which occurs in drier localities, by the presence of Saxifraga spathularis BROT.

7. Cheilantho-Asplenietum conmnensis PINTO DA SILVA corr. ORTIZ et RODR[GUEZ-OUBIIT/A hoc Ioco (PINTO DA SILVA 1965: 17, synoptic table)

Following Article 43 of the Code of the Phytosociological Nomenclature, we hereby correct the name of the described association of the serpentines of the northeastern Transmontano area of Portugal originally named Cheilantho-Asplenietum cuneifolii by PINTO DA SILVA (1965). Correction is necessary because the representative of the genus Asp/en/um is in fact A. ad/antwn-n/gnan L. var. corunnense ~ in accordance with NOGUmRA and ORMOtCOE (1986) and HORJALF_S (1986). To this association we therefore classify (at least

This association generally colonizes natural or artificial stony slopes. Since/t tolerates high-nitrogen conditions, it is frequent on roadside banks.

It is distributed mainly in the coiline bioclimatic belt, above aU in the ThermocoU/ne Subbelt, and particularly in the lower levels of the Upperconine SubbelL

The new association is very reliably characterized by the presence of the two taxa that give it its name: Seswno/~ suJj~ut/cosa (I..~GE) O. Kumze and ~ dur/m/num (BRO'r.)

Two additional taxa, both absent from the Galician association, D/anthus ~ t a n u s BRor. and Ant/rib/hum gran/t/cum ROTHM, also occur there. This association is probably a Mediterranean vicarious association of the S e s m m ~ / d o - ~ dur/m~, which has an almost entirely Eurosiberian distribution in Galicia. The other associations of the alliance RumiciDkmth/on &.v/tan/have a floristic composition very different from the Ananh/nenon dut /m~.

These two species characterize the subassochRion S e s a m o / d o - ~ dur/mbtf r i C o . c u r e /ad/Ara~, which is typical of this tran~itionaJ zone. Inside the Orensano-Sanabriensian sector, it is replaced by the ehagna/o-Rwn/cetum/ndurat/, with the endemic taxon Ananh/num due/m/hum (BgOT.) PERS. being replaced by A. be///d~o//wn (L.) When. Probably, towards the Lusitano-Duriensian sector, this same subassociation marks the tral~tion towards the community mentioned by Ss RODRIOU~ et aL (o13. cit.). From the biogeographical point of view, the new association is distributed throughout the Galaico-Portuguese sector and penetrates slightly into the western extreme of the Orensano-Sanabriensian sector.

in the Montane belt of the Juresiano-Queixensian sector. The floristic composition of these stands is very similar to Phalacrocarpo-Saxifragetum continentalis, but the Phalacrocarpum is represented by P. oppositifolium (BROr.) WILLr~ subsp, hoffmannseggii (SAMP.) NmTO instead of the typical subspecies, whilst Dianthus lusitanus BROr. appears frequently. These stands, which border the distribution area of Phalacrocarpo oppositifolii-Saxifragetum continentalis on the south, may represent a subassociation of the latter or an independent association. The data currently available do not allow us to incline, for the moment, towards any one of the two options.

The pteridophytic association Gymnogrammo-Davallietum canariensis is very common on artificial walls and moist crags which have a compact moss layer - dominated by the bryophytes Homalotecium sericeum HEDW., Tortula rnuralis HEDW., Bryum bicolor DICKS., Targionia hypophylla L., Porella platyphylla (L.) P~IFF., Lejeunea cavifolia (EHRH.) LI~DB., etc., which are abundant in Galicia due to the effects of the high humidity, especially in shaded areas.

Within this association, two subassociations can be clearly recognised, one of which is characteristic of sheltered areas of the Thermocolline subbelt, where the climate is mild and free of frost and has permitted the survival of the macaronesian relict taxon Davallia canariensis (L) SM., whose presence characterizes this subassociation, and the other widely distributed in the Eucolline and Upper colline subbelt as well as some areas of the thermocolline subbelt where the adverse climate has impeded survival of Dava/l/a canar/ens/s.

Of the 5 relev6s included in the original table, Davallia caaariensis (L,) SM. is only present in one (relev6 4). Since the name of the association is Uymnogrammo-Davallietum canariensis, the selection of relevr 4 as the typus of this association name and of the typical subassociation Gymnogrammo-Davallietum davallietosum canariensis appears to be the most coherent choice. For the other subassociation we have selected the name

Besides 5 relev6s published by BELLOT and ~ (1959, Tab. 1) we present 22 original relev~s of this association in Tab. 7, of which, numbers 1 to 13 correspond to the subassociation Gymnogrammo-Davallietum po/ypod/etoswn/merject/and numbers 18 to 27 to the subassociation Gymnoffwnnw-DavaUietum davallietoswn omaden~.

As we stated at the outset, this siliceous association occurs mostly on art i f ic ial walls, where it is richest in species (relev~s 1-9, 18-21), as well as on natural crags, where it is poorer in species (relev~s 10-11, 22-24), and, in epiphytic form, on tree trunks, with generally no more than 2 or 3 species per relev~ (relev~s 12-13, 2.5-26).

On the basis of our data, the existence of the association Silene acutifolia-Holcus gayanus BELLOT 1951, which BELLOT (1966) considered to be related to Gymnosrwnmo-Dava///etum canar/ens/s, is not sufficiently verified.

Polygonuln capitatu~ community Table 8

This is a community which occurs on artificial walls, in urban habitats of the Portuguese area of the Mineasian subsector (Galaico-Portuguese sector) where its optimum area of development is found. It is characterized by the abundant presence of the adventive species from the Himalayas Polygonum cap/tatum D. DoN. The rest of the floristlc composition does not differ very much from that ofParietarietum judaicae ~ 1928.

We have found this community only in the extreme southwestern area of Galicia.

Rumex scutatus subsp, gallaecicus community Table 9

This community colonises the serpentine dunite and eclogite mobile rock slides on the cliffs of the A Capelada peninsula, in the north coast of Galicia. It is characterized by the presence of Rumex scutatus L. subsp, gallaecicus LAGO, which is endemic to this locality.

Its syntaxonomic rank and position are problematic, among other reasons, because the independence of the serpentinicolous populations of Rumex scutatus at a subspecific level is not clear (L6PEZ Gor~zAtEZ 1990). On the other hand, plants belonging to Thlaspietea rotundifolii BR.-Bt. 1948 and its subdivisions are scarce in floristic composition of the community.

We hereby correct the name of the association Cryptogrammo-Silenetum herminii FE~Ar~EZ PRIMO 1983, in accordance with Article 43 of the Code of the Phytosociological Nomenclature, since the taxon which forms part of the name of this association does not correspond to the Sitenefoetida L I ~ type (with which S. herm/n/is synonymous) but to S//ene foet/da subsp, gayana TALAV'EgA (TALAVERA 1988, 1990)

Rumex suffnaicosus community Table 10

This community is flofistically characterized by Rumex suffruticosus GAY ex MEISSNER and Phalacrocarpum oppositifolium (BRoT.) Wn.LX. subsp, oppositifolium. It occurs in the Oromediterranean belt principally over dry mobile rock slides, principally quartzitic, formed of medium-sized rock fragments. Although initially Izco et ORrtZ (1987) included it into the association Phalacrocarpo-Rumicetum suffruticosi RIVAS-MARTINEZ 1981, we now think that this latter is restricted to the Serra da Estrela (Portugal) where it is distinguished by the endemic plants Silenefoetida LINK subsp.foet/da and Senecio cespitosus BROT.
