•4,5—-5 mm long and 2 mm wide, biflorous, sparsely hirsute. Glumae unequal, lower one 3—4 mm long, narrowly lanceolata, upper one 3,5—4,5 mm long, acute or obtuse. Lemmae 4—4,3 mm long, acute or finely attenuate, very minutely and appressedly pubescent, paleae 3,6—4 mm long, bicarinate, hyaline, acute. Antherae 2,2 mm long. The new species is without doubt a member of the Series Arenariae UJH. Its stature resembles that of Koeleria albescens DC, but differs by its dense pubescense (of quite another character in Koeleria albescens DC). As a plant of the higher montane regions, the panicle has a violet suffusion. Koeleria albescens Dc. is a much taller plant. Their areas do not meet, since in France it does not reach the Alps. The new species probably inhabits many more localities than DOMIN'S Neuchatel and those in the Reusstal listed here, because these plants were recorded as Koeleria eristata (L.) PERS. Its relict character is evinced by the scattered occurrences — not a unique phenomenon in Europe. Such plants are, e.g., Koeleria javorkae UJH. from the Hungarian Basin, inhabiting only the tussocks of the Great Plain, further Koeleria nyaradyi UJH. in Transylvania, Koeleria besserii UJH., -of a Baltic range [which I found, going after a single herbarial datum of 40 years ago, in the living state on a small (500 m

) site in June, 1973], and also Koeleria pyrenaica (DOM.) UJH. Accordingly, the fine endemic species should be rehabilitated in the Swiss flora. Koeleria schroeteriana (DOM.)
