originating from 1935. The area of the plant is Easter Baltic, its nearest habitat far removed to the north from Hungary. In the same locality but in 1972,1 found among the masses of Koeleria eristata (L.) PERS. em. BORB., widely ranging and occurring profusely also on pastures, two specimens — on a pasture along the forest (the locality of famously rare Pulsatilla species!) —- of Koeleria nyaradyi UJH., a species I described (ÚJHELYI 1970) after an exemplar collected on the Mt. Morgó near Kolozsvár (Cluj), Transylvania, and preserved in E. Gy. NYÁRÁDY. In 1965, I failed to rediscover it in the locus classicus. This plant grows by ones and twos, in very small individual numbers, and one needs some luck, too, to detect its presence. On the look (in the Mts. Kőszeg, W Hungary, in 1973) for Koeleria pubiculmis (HACK.) UJH., a serpentiphilous species on the Austrian side of the same range — and I could not find it even after some years of search — I found the second locality in Hungary of the Atlantic Koeleria mollis MANN (ÚJHELYI 1970). In the same way I happened in several localities in Bulgaria in 1969 on Koeleria skorpilii (PODP.) UJH., (ÚJHELYI 1966), a plant which was absent from not only all Bulgarian herbaria, but aside of whose single holotype deposited in Budapest I foundno second exemplar in any herb arium. These are only some examples of the chacy state of circumstances to come upon such relict species — taxa wich exist in small populations and thus escape our attention among the other Koelerias of general distribution. On this basis and untill the contrary is proved by genetical experiments, namely its hybrid state, Koeleria alpigena DOMIN must be regarded as a beatiful endemism of the Swiss flora. Indicated by a question-mark, DOMIN placed two other plants in the cover on which he wrote the name Koeleria alpigena. One of them has the data : gracilis ei alpigena?

, Iserobloss, 22, 5, 90. H. L. The form of the basal leaves, the also strongly glaucous and rigid blades, their vaginae and the epidermal structure of the unterside of the leaves are similar to those holotype of Koeleria alpigena DOM. The vetust vaginae are whitish and similarly decayed by the action of fungous mycelia, the leaves comparatively short, rigid, glabrescent. I cannot wholly identify it with Koeleria alpigena DOM. ; the anatomical picture of the underside of the leaves is reproduced in Plate V Fig. 1. The other specimen is also a duplum in DOMIN'S herbarium : K. grac. Ssp. nova Iserobloss, leg. 21, V, 40, FAVRAT. H. Polyt. Zürich. Herbarium K. DOMIN. The epidermal structure refers to its identity with Koeleria eristata (L.) PERS. em. BORB. Following Koeleria alpigena DOMIN, DOMIN described in his monograph (1907) Mannagettae DOMIN, marked by an * and as a race of Koeleria alpigena DOMIN. Investigations have shown that it does not belong under Koeleria alpigena DOMIN, and that it is not a hybrid of "Koeleria vallesiana and Koeleria gracilis", but a distinct species. 55.
