also here the exsiccate specimen of HUTER, PORTA, RIGO, ex itinere hispanico 1879, Nro. 656. K. setacea PERS. I have made an epidermal preparation also from the specimen in the Herbarium of the University of Zürich. Not only the epidermis, but also every other feature of the plant demonstrate its identity with Koeleria andreánszkyi UJH., except for the very narrow, convolute leaves. The plant is an endemism of the Sierra Nevada; its alliance with the Series Caudatae UJH. is very probable. Below the external epiderm of the setaceous, convolute leaves, there is a homogeneous sclerenchyme layer, the same as in the blades of Festuca vaginata W. et K. This xeromorphous structure is responsible for the homogeneous configuration of the epiderm above it, the complete hairlessness (not even the vestiges of the hairs are present), the strongly sinuous cellular walls, as well as the appearance of the cork and silica-body twin-cells (Plate IV, Fig. 3). This phenomenon also corroborates the considerations on the role of setaceousness of the leaves within the family Gramineae, as expounded in the Hungarian Biological Itinerary Congress in Debrecen in 1960 (4). There are two erroneously identified herbarial sheets, under the name Koeleria crassipes LGE., in the Herbarium of the Botanical Gardens of Madrid. One of them is from Santalla (Lugo) collected by P. MERINO in 1900, identified as Koeleria crassipes LGE., and revided by E. PAUNERO as Koeleria caudata (LINK) STEUDEL var. crassipes (LGE.) MAIRE subvar. setosa DOMIN, 1956. In all probability, the plant is a strongly elongated, setosely leaved specimen of Koeleria splendens PRESL (MA, nr. 9792). The other specimen derives from M. GANDOGER'S collecting: Cantabria, Pena Labra, 1900 m, 26, VII. 1894, identified as Koeleria crassipes LGE. forma. In E. PAUNERO'S revision: ejemplar incompleto K. albescens? The specimen consists only of three panicles with stalks. The anatomical structure of one of the small culm-leaf, as well as the features of the panicle and the spikelets, refer to its identity with Koeleria splendens PRESL (MA, nr. 177285). IX. Series Degenii ÚJHELYI series nova IX. Series Degenii ÚJHELYI series nova Vaginis foliisque rigidis, glaucescentibus, paniculis densis, vel densissimis, palliais, spiculis subhirsutis, lemmis aristatis, vel acuminatis. Characteristic of the members of the Series is their extremely compact, dense lawn. The basal leaves are short, rigid, glaucescent, the basal sheaths bulbously incrassate, and also short. The blades are glabrous or merely scabriusculous, the culm is rigid, the panicle compact, cylindrical or oblongo-ovate, pallid. I have discussed the tetraploid member of the Series, Koeleria decjeni DOM., in one of my papers on the Koeleria species (7). I have pointed out that K. DOMIN'S Sectio Bulbosae subsectio Imbricatae, together with his other groupings, are artificial and comprise of habit-types. I have also shown that the Series Hirsutae UJH., extracted and described from this Subsection, consist of species inhabiting exclusively the Alps without the least relationship to Koeleria decjeni UJH. of a Pontic range. In the course of working up the taxa of K. DOMIN'S Subsectio 4. Splendentes, I have also demonstrated (9, 10) that DOMIN grouped together heterogeneous species. The majority of the species included in it are utterly unrelated to each other. Koeleria splendens PRESL, as interpreted by K. DOMIN, is especially heterogeneous and contains taxa of diverse ranks. I have treated Koeleria callieri (DOM.) UJH., the hexaploid member of the Series Glaucae UJH., and Koeleria csatái UJH., the hexaploid
