As in other localities where it is present, it is integrated in Mediterranean pteridophyte chasmophyte communities belonging the association Cheilantho maderensis-Cosentinietum velleae (Tabla 1, rels.
In drier zones, these rock faces feature a characteristic vegetation corresponding to the endemic association Phagnalo saxatilis-Antirrhinetum lopesianii, whereas in moister, oozing areas there are chasmophyte communities typical of rock formations periodically flooded by water containing calcium carbonate corresponding to the alliance Adiantion capilli-veneris (Table 1, rels.

The eponymous species of the Inulion heterolepidis is Inula heterolepis Boiss., an east Mediterranean chasmophyte. The Campanulo hagieliae-Inuletum heterolepidis, chosen here as the holotypus of the alliance, is based on releves from the Dodecanese Archipelago (Rhodes, Samos, Ikaria).
This is probably the case in the more marginal of the section Polium species, such as those of subsection Rotundifolia (Sauvage & Vindt, 1955) or of subsection Simplicipiliosa (Puech, 1976), especially those, such as chasmophyte paleoendemics (Puech, 1976; Crespo et al., 1990), that are narrowly distributed and that occupy the most specialized environments.
The correction of the suballiance name, which forms the basionym for the new alliance, is necessary, because Helichrysum orientale (L.) DC., a conspicuous, obligate Aegean chasmophyte (Zaffran, 1990), does not occur in phrygana except in ungrazed areas and in the neighbourhood of rocks.
A similar disjunction is represented by Scrophularia xylorrhiza, a perennial chasmophyte with a lignified basis, which grows in cliffy section of habitat 2 below peak l [ILLUSTRATION FOR FIGURES 23 & 24 OMITTED] and in the cliffs of Arbel, by the Sea of Galilee north of Tiberia, 265 km north of Nahal Elot.
Another disjunct species is the cliff chasmophyte Rosularia lineata, which has a gap of about 80 km to the population at Nahal Hava, in the Negev Highlands, then 60 km to near Arad, in the northeastern Negev, and then 90 km to eastern Samaria.
In the Carabaya we recognize four vegetation formations: puna grasslands; rock vegetation dominated by chasmophytes; high Andean wetlands; river shores and lakes, and periglacial areas including cryoturbated soils and subnival pumices (Weberbauer 1945, Galan de Mera et al.
