owing to the partly elongated panicle; these latter are pale greenish or with a weakly violet suffusion. Since the plant derives from the lower region of the Grigna Group, in dry meadows according to GEILINGER, the plant is longer than the dis­cussed specimens of the nominate form. Owing to the uniform panicle, the weakly violet hue of the spikelets, and the long and thin glumae, DOMIN assumed the plant collected on the "Val de lia Farina Seeseite des S. Martino" to represent a variety different from subvar. Geilingeri DOM. However, the very characteristics he stressed refer to Koeleria montana (HAUSM.) D.T., which species never even entered his mind, thinking the specimen assignable exclusively to Koeleria splendens PRESL. Incidentally, the Koeleria cristata (L.) PERS. em. BORB. specimens, collected by GEILLNGER also on the Grigna Group, are similarly elongated, with long blades and panicles. It is not without interest that SUESSENGUTH (HEGr 1935) did not mention either Koeleria solendens PRESL nor subvar. Geilingeri DOM., while the latest great Swiss floral work (HESS, LANDOLT & HIRZEL 1967) lists Koeleria splendens PRESL, omit­ting var. pyramidata DOM. subvar. Geilingeri DOM. For the Swiss flora, they record the Grigna Group, and the authors record Koeleria splendens PRESL data also for the SW and SE Alps. I have not seen these specimens. My studies have already shown that Koeleria splendens PRESL inhabits only the SW Mediterranean, without extending from the Appenines to the Alps. The areal data of the floral work surely refer to other species. Ah other data of the areal hst refer to other species. They had all been relegated by K. DOMIN to the Formen­kreis of the great-species Koeleria splendens PRESL (ÚJHELYI 1964, 1965, 1966, 1968, 1972). This case again witnesses that the really existing evolutional species have not been extensively clarified since DOMIN'S Monograph, and only the subspecific hierarchy has been omitted. By this, however, still more faulty data have been introduced to literature. The problem of Koeleria eriostachya (species collectiva) Domin Of the other units composing DOMIN'S II. Sectio Caepitosae 2. Subsectio Caespi­tosae verae b. Tribus Cristatae subtribus Cristatae verae, he relegated to Eriostachyae DOMIN species which, according to DOMIN, can be characterized by being usually green or greenish, their culms more or less pubescent, their larger spiculae mostly colored, the spikelets wider, more or less hirsute, and only rarely glabrous. Of these species I propose to submit here critical remarks concerning only a part of the European taxa of Koeleria eriostachya (species collectiva) DOMIN. The other two species, Koeleria Ledebouri DOM., and Koeleria subaristata (PANC.) DOM. are characterizable by glabrous spikelets. DOMIN drew the area of Koeleria eriostachya, species collectiva, from the Pyre­nees to West Asia. According to his view, Subs p. I. eriostachya PANC. inhabits the Eastern Alps and the Balkan Range, Subsp. II. K. Schroeteriana DOMIN the Wes­tern Alps and the Pyrenees, Subsp. III. K. caucasica (TRINER) DOMIN Asia Minor, the Caucasus, West Asia, and Subsp. IV. K. Albovii DOMIN the Caucasus. The contraction of these taxa, widely differing in their disjunct areas and eco­logical requirements, should in itself have been a warning for a careful handling. I found their evolutional anatomical examinations revealed that we are confronted here with the same phenomenon of convergence as in the cases of the great-species Koeleria splendens PRESL sensu DOMIN or the coUective species Koeleria pyramidata.
