Abstract

This is a study of the terricolous bryophytic vegetation in the Murcia province (Southeastern Spain), introduced with some comments on geographical situation, relief, geology, pedology, climate and a short exposition of the higher vegetation of this region. Using the sigmatist methodology we recognize and describe in detail 14 associations and one terricolous bryophytic community in this area. We include these communities in five phytosociological classes, agreeing with the following syntaxonomic scheme: Barbuletea unguicuiatae von Hübschmann 1967, (On naked soils or protosoils with basic or neuter pH) Barbuletalia unguicuiatae von Hübschmann 1967 (Meso-xerophilous communities with Eurosiberian or subhumid-humid Mediterranean optimum) Phascion mitraeformis Waldheim 1947 (Xerophilous, slightly nitrofilous communities suffering a rather lengthy annual dry season) Riccietum atromarginato-lamellosae as. nova (Photophilous community on compact, trodden, sometimes slightly nitrified soils) Trichostomo-Aloinetum aloidis Guerra & Varo 1981 (Photo-sciophilous pioneer community on not or hardly nitrified marl-limestone slopes) Mannion androgynae al. nova (Mediterranean communities of talose Hepaticae mainly hepaticochamaephytes. A southern vicariant of Grimaldion fragantis Smarda 1957) Riccio nigrellae-Oxymitretum paleaceae as. nova (On hardly compact, neuter to slightly acid (pH = 6.4-7.1) soils in (locally volcanic) rock crevices or shelves) Tortellion flavovirentis Guerra 1982 (Communities on little compact, frank-sandy soils) Tortello-Bryetum dunensis Guerra & Puche 1984 (On dry oligotrophic sandy soils in coastal sands, dunes, etc.) Pleurochaetion squarrosae Neumayr 1971 sensu Giacomini 1951 non Marstaller 1980 (Terri-humicolous, bryochamaephytic communities colonizing basic soils) Homalothecio aurei-Pleurochaetetum squarrosae as. nova (Meso-xerophilous community on deep, developed soils as well as protosoils, always humiferous, on limestone rocks) Homalothecium aureum-Scleropodium touretii community (Sciophilous mesophilous community on shady slopes of deep ravines) Cephaloziello-Southbyion nigrellae Guerra & Gil 1982 (Meso-xerophilous communities on protosoils in shallow rock crevices, limestone cement of conglomerates, walls, etc. ) Gymnostomo luisieri-Southbyetum nigrellae (Guerra & Gil 1982) nom. corr. (On humid, non-oozing limestone protosoils) Tortulo brevissimae-Aloinetalia bifrontis ord. nov. (Markedly xerophytic Mediterranean and Irano-Turanian basophilous communities. Iberian optimum in the arid-dry Mediterranean area) Aloino-Crossidion crassinervis al. nova (Communities of this ordo developing on clayey, marl-clayey and gypsiferous soils) Crossidio crassinervis-Tortuletum obtusatae as. nova (On marl-gypsiferous and gypsiferous soils) Acaulo triquetri-Tortuletum brevissimae as. nova (On clayey or marl-clayey soils) Pottio-Riccion crustatae al. nova (On saline soils with middle or high conductivity) Riccietum crustatae as. nova (On temporarily humid - being subjected to temporary hydromorphy - saline soils) Crossidio crassinervis -Pottietum commutatae as. nova (On dry saline soils) Funarietalia hygrometricae von Hübschmann 1957 (Communities on extremely nitrified soils. Only one alliance Funarion hygrome-tricae Hadac 1936) Funarietum hygrometricae Gams 1927 (Locally on usually burnt up soils with high nitrate rates [107-128 mgr/gr of soil]) Tortulo-Homalothecietea sericei Hertel 1974 (Bryochamaephytic, saxicolous or terri-saxicolous [chasmo- or exocomophytic] communities) Ctenidietalia mollusci Hadac & Smarda 1944 (Chasmocomophytic communities. Only one alliance Ctenidion mollusci Stefureac 1941) Encalypto-Fissidentetum cristati Neumayr 1971 (In small cavities of limestone or dolomitic rocks) Montio-Cardaminetea Br.-Bl. & Tüxen 1943 (Eutrophic or oligotrophic, photo-sciophilous, usually bryocormophytic aquatic communities on the banks of brooks, springs, etc.) Cardamino-Cratoneuretalia Maas 1959 (Basophilous eutrophic communities) Cratoneurion commutati W. Koch 1928 (Communities subjected to strong flow intermittences, evaporation and water temperature variations, and also to water purity decrease) Eucladio-Didymodonetum tophacei Hébrard 1973 (On protosoils on the base of waterfalls and intensely oozing walls on vertical limestone rocks) Fontinaletea antipyreticae von Hübschmann 1957 (Rheophilous or hydatophytic communities colonizing rocks and - more rarely - soils on the beds of rivers and brooks) Leptodyetietalia riparii (Philippi 1956) Hertel 1974 (Basophilous rheophilous communities) Cinclidotion fontinaloidis (Gams 1927) von Hübschmann 1953 (Temporarily submerged communities) Hyophiletum ehrenbergii von Hübschmann 1957 (On the beds and banks of rivers and brooks on limestone rocks and sometimes on the earthy substratum of the bed edges)
