Syntaxon descriptions: Bartramio strictae - Carici asturicae

Bartramio strictae-Polypodienion cambrici (O. Bolòs & Vives 1957) suball. nova hoc loco, stat. nov. (30.1b)

[Sedo cepaeae-Polypodienion serrulati M.B. Crespo in Ecol. Medit. 19: 6. 1993 (art. 27), Pterogonio gracilis-Polypodienion vulgaris M.B. Crespo in Ecol. Medit. 19: 8. 1993 (art. 27)]
(Polypodion cambrici, Anomodonto-Polypodietalia, Anomodonto-Polypodietea)

Typus suballiancia (holotypus): Sedo-Polypodietum serrati O. Bolòs & Vives in Collect. Bot. (Barcelona) 5(2): 533. 1957.

Characteristic species (dif. suball.): Sedum cepaea L., Bartramia stricta Brid., Exormotheca pustulosa Mitt., Sedum hirsutum All., Targionia hypophylla L., Hylotelephium maximum (L.) Holub in Severŏces.

Diagnosis: Epiphitic and comophytic shaded communities of rhizomatous ferns (mostly Polypodium cambricum), bryophytes and seed plants of rainy Temperate and Mediterranean oceanic territories, growing on nutrient-poor substrata.

This new suballiance is included in the alliance Polypodion serrati Br.-Bl. in Br.-Bl., Roussine & Nègre, Group. Vég. France Médit. 1952 (Polypodion cambrici (30.1) nom. mut. propos.). At the same time by the art. 28 (CPN 2000) a second suballiance that contains the original diagnosis of the alliance and the nomenclatural type must be denominated - and since 1.1.1979 the name of the second suballiance that includes the type must be formed solely by altering the rank-indicating termination - consequently: 30.1a. Polypodienion cambrici (serrati) suball. nova, that correspond to the nutrient-rich substrata communities of the same territory and environmental conditions.

Beto maritimae-Lavateretum arboreae ass. nova hoc loco (34.4.6 = 37.4.2)

(Dauco-Melilotion, Artemisietalia vulgaris, Artemisietea vulgaris)

Typus associatio: Table 13, rel. 2 [Asturias: Cudillero, Islote de Grados. 29TQJ2230. 0-10 m, 10 m²].

Characteristic species (territorials): Lavatera arborea, Beta maritima, Matricaria maritima.

Diagnosis: Community of Lavatera arborea and Beta maritima growing on soils with great accumulation of marine birds" droppings, and whose optimum is in littoral Cantabrian-Atlantic areas scarcely visited by men, mainly in the rocky isles. Besides the nitrohalophilous and halophilous plants common in the cliffs, in these communities there are nitrophilous species from non-saline environments. The Cantabrian-Atlantic association Beto-Lavateretum arboreae can be in contact with the communities of Crithmo-Armerion maritimae, with the aerohaline heaths of the Dactylido maritimae-Ulicion maritimi and not too far of the chasmophyte nitrophilous aerohalitic marine forb communities of Brassicion oleraceae (Parietarietea).

Laserpitio eliasii-Coryletum avellanae Puente, M.J. López, Penas & F. Salegui ass. nova hoc loco (76.14.2) (*)

Typus associatio: Table 15, rel. 4 [León: Robledo de Caldas. 30TTN6257. 1280 m, N, 20%, 200 m2].

Characteristic species (territorials): Corylus avellana, Crepis lampsanoides, Genista occidentalis, Helleborus occidentalis, Laserpitium nestleri subsp. eliasii, Mercurialis perennis.

Diagnosis: Preforests of the basophilous and xerophilous beech forest Epipactido helleborines-Fagetum sylvaticae laserpitietosum eliasii F.J. Pérez & T.E. Díaz 1987, developed on base rich soils (coming from limestone) on steep, Northern exposed slopes of supratemperate humid Orocantabric territories. By decreasing depth and development of soil, they are in zonation with thickets of Pruno spinosae-Berberidetum cantabricae, and the furze formations of Lithodoro diffusae-Genistetum occidentalis.

In these microforests of Corylus avellana and Crataegus monogyna, they are sometimes accompanied by Sorbus aria, Viburnum lantana and Lonicera xylosteum in the tree-shrub layer; in the herbaceous layer Hepatica nobilis, Mercurialis perennis, Melica uniflora, Milium effusum, Bromus ramosus, Sanicula europaea and Laserpitium nestleri subsp. eliasii, are common or even dominant. The presence of species belonging to Berberidion vulgaris is very important, and they behave as differential against other associations. Floristically, this association can be differentiated from Hepatico-Coryletum because it lacks Pulmonaria affinis, Betula pendula, Buxus sempervirens and Daphne mezereum, among others. It can be differentiated from Polysticho-Coryletum because it lacks Campanula trachelium, Hedera helix and Quercus ilex and it is different from Astrantio majoris-Coryletum because it lacks Hypericum hirsutum, Satureja vulgaris, Salix alba, Campanula trachelium, Berberis hispanica and Acer campestre. It can be differentiated from other formations, in which the hazel is dominant, Luzulo henriquesii-Aceretum pseudoplatani and Omphalodo nitidae-Coryletum avellanae, because it lacks Acer pseudoplatanus, Ilex aquifolium, Quercus petraea, Fraxinus excelsior, Fagus sylvatica, Omphalodes nitida, Saxifraga spathularis and Luzula sylvatica subsp. henriquesii, among others. It is also different from all of them because it has the following species Laserpitium nestleri subsp. eliasii, Lithodora diffusa, Genista occidentalis, Berberis vulgaris subsp. cantabrica and Rhamnus alpina, among others.

Linario triornithophorae-Coryletum avellanae R. Alonso, Puente, Penas & F. Salegui ass. nova hoc loco (76.14.3) (*)

Typus associatio: Table 16, rel. 2 [León: Boca de Huérgano. 30TUN4259. 1130 m, NW, 25%, 100 m2].

Characteristic species (territorials): Betula celtiberica, Corylus avellana, Genista polygaliphylla, Linaria triornithophora, Vaccinium myrtillus.

Diagnosis: Fast-growing deciduous microforests formed by Corylus avellana, Sorbus aucuparia, Sorbus aria, Quercus petraea (little trees) and Frangula alnus that live in deep, fresh and acid soils in the supratemperate humid-hyperhumid belt of the Altocarrionese Subsector. They constitute the secondary microforests that replace the climactic Orocantabric sessile oak mesoforests of the Linario triornithophorae-Quercetum petraeae. They differ from the Ubinnean and Campurrian-Carrionese association Laserpitio eliasii-Coryletum avellanae by the presence of Linaria triornithophora and Vaccinium myrtillus, and also by the absence of the basophilic taxa Amelanchier ovalis, Rhamnus alpina, Laserpitium nestleri subsp. eliasii, Daphne laureola var. cantabrica, etc. They differ from the Northern Galician-Asturian and Lacian-Ancarensean association Omphalodo nitidae-Coryletum avellanae by the presence of Linaria triornithophora and Helleborus viridis subsp. occidentalis and by the absence of Omphalodes nitida, Acer pseudoplatanus, Saxifraga spathularis and Phyllitis scolopendrium.

Typus associatio: Table 22, rel. 3 [Madrid: Sierra de Guadarrama, Pinilla del Valle, El Nevero, Hoyos de Pinilla creek. 30TVL2736. 1950 m, 6 m2 ].

Characteristic species (territorial): Festuca rivularis.

Diagnosis: Mat-grass swards characterised by the geniculated fescue Festuca rivularis, growing on peaty soils bordering springs and rivulets subjected to long periods of snow cover and to temporary inundations by thaw, running and oxygenated water. These chionophilous and rheophilous mat-grasslands are known from the high mountains of the Iberian Central System (Estrelensean, Bejaran-Gredensean and Guadarramean Sectors), where they appear in the (upper supra) oro-cryorotemperate submediterranean belts, but they also exist with some differences in the Orensan-Sanabriensean Sector and in the siliceous massifs of the Orocantabric Subprovince.
