Exemplaria altera: Flora der Schweiz. Koeleria hirsuta GAUD. var. Schinzii DOMIN Oberengadin: Chaste. 21.7.11. leg. A. R. PAUL. Schedula TJJHELYII: Koeleria schinzii. (DOM.) ÚJHELYI. Rev. ÚJHELYI (Hb. BOROS). In its whole habit, the plant differs from Koeleria hirsuta (LAM. & DC.) GAUD. The large, many-flowered spikelets, the considerably bigger and decidedly ample panicle, the greater dimensions of the glumae, lemmae, and paleae, as well as the robust state of the plant allude to a distinct taxon. Its rank can be decided only by investigation of a live material, without which the decision is only theoretical. The problem of Koeleria splendens Presl 3. var. pyramidata (DOM.) DOM. S subvar. Geilingeri DOMIN When establishing the Series Ciliatae UJH., I have stressed the most important features of this evolutional series restricted to the Alps (ÚJHELYI 1970). The dip­loid (Koeleria montana (Hausm.)) D.T. as weh as the other members of the series are characterized by the expressed extra vaginal innovation and the resultant ces­pitosity, the glabrous vaginae, the elongated, glabrous, glaucescent, or obscure blades, the narrow and interiorly interrupted panicle, and the glabrous and splen­dent spikelets. The basis of my detailed Latin description was a plant collected by G. GEILINGER on the Grigna Group, an exemplar identified by K. DOMIN as K. mon­tana (HAUSM.) D.T. (Herbarium GEILINGERI). The three specimens, originating also from the Grigna Group and preserved in the Geilinger Herbarium of the Botanical Museum of the University of Zürich, served for DOMIN'S description of his Koeleria splendens PRESL var. pyramidata (DOM.) DOM. subvar. Geilingeri DOM. It should be borne in mind that of the herbarial data listed for Koeleria splen­dens PRESL var. pyramidata DOM. in his monograph only a single specimen repre­sents Koeleria splendens PRESL and all others are referable to divers species. He drew subvar. Geilingeri DOM. under the variety mentioned probably because of its strongly elongated and lobate panicle. He regarded the wholly glabrous and the­refore splendent spikelets and the incrassate rhizome as Koeleria splendens PRESL features, but failed to consider its conditions of distribution. I have already stressed in my introduction that an unilateral assessment of the finer hfe-form characteris­tics confuses the evolutionary view. The basis of his Latin diagnosis and concurrently the source of DOMIN'S erro­neous evaluation is his holotype: "Rhizomatibus minus incrassatis sed senio sublig­noso-fatiscentibus, culmis gracilioribus usque 6 dm altis, foliis longioribus glaucis subrigidis planis c. 1—2 mm la-,is pro more laminis plus evolutis instructis, paniculis quidem lobati sed semper angustis (lobis brevibus) laxioribus subinterruptis albescenti­nitididis, spiculis 5 1/2 usque 6 mm longis 3- vel 2­f loris". Its rhizomes are thick, sublignose, fatiscent (a result of subterranean decay : the interwoven fungal hyphae are still present on the fatiscent vetust vaginae, the cause of their white fatiscence). It escaped DOMIN'S attention, and because of the overstressing of the above features
