Actualisation de la flore du territoire des Hautes Alpes.
Résumé
Many new taxons have been discovered in HautesAlpes (southern alps, France) since 1994, date of publishing of a botanical atlas over this territory (CHAS, 1994). New stations have also been discovered for noteworthy species in regard to their rarity or distribution. Consequently, 104 new taxons are mentioned for the first time in the studied zone. The majority of these new species (43%) has a ruderal strategy, and 18% of them are neophytes. Besides, 6 of these new mentions are due to taxonomics reviewing of local populations (Arum cylindraceum, Cynoglossum montanum, Fritillaria burnatii, Linaria vulgaris, Luzula alpina, Schoenoplectus lacustris). The reviewing of the local distribution of 98 taxons is also lead, taking intout acount the rarety of these species or the originality of the new data. Finally, 12 species escaped from the Lautaret alpine garden (2100 m) are presented in regard to their long term naturalization possibility.
