| Résumé : |
Festuca eskia, a subalpine species of the pyrenean subalpine level, in reality actually consists in different types. One of them is characteristic of the geomorphogenic periglacial hill-sides, the other is characteristic of the biostatic habitats. The same is valid as regards the two types of Trifolium alpinum. Among identical conditions Campanula ficaroides opposes C. recta. As regards, Festuca paniculata, it is related to another type of Trifolium alpinum on the sub-alpine, high, cryoclastic hill-sides, while on the biostatic habitats it is related to Campanula precatoria. Therefore, the dynamics of the hill-sides remarkably indicates the speciation of the data, which are different both as regards their morphology, and their chemistry, that is their total amino-acid contents and proline in particular.
