Ujhelyi, J.: Data to the systematics of the sections Bulbosae and Caespitosae of the genus Koeleria, XI.

On the basis of the data given above, the area of Koeleria eriostachya PANC. is strongly restricted, including only, the high mountains of Serbia and Bulgaria. The plant lives in expressedly subalpine and alpine communities, in my own experience partly in dwarf shrubberies partly in sterile pioneer associations, or in closed alpine or subalpine swards. T. Pócs's association surveys in the Central Balkan also corroborate this statement. Further removed from this area, the plant appears in a disjunct occurrence in a restricted locality in the SE Retyezát of the South Carpathians. Both I. CSŰRÖS and S. PAP collected it there ; I submitted the exact data for the sake of completeness when discussing the nominate form. In treating Koeleria tenuipes (SCHUR) UJH. in my 1965 paper, I included under that taxon, as a result of a perfunctory examination, also a third specimen. Less informed at that time about Koeleria eriostachya PANÖ., nor having seen Koeleria tenuipes (SCHUR) UJH. in its site, I considered its very best herbarial specimen a Koeleria eriostachya PANC. exemplar. I was confused by its robust stature (70 cm), the more than 10 cm long and hirsute panicle. Principally the preparation of a leaf-epiderm slide and its study, but also a more thorough examination of thewhole plant convinced me that this earlier publication was precipitate. In the summer of 1972 I was able to see personally the locus classicus of Koeleria tenuipes (SCHUR) UJH., the Piatra Mare (Nagykőhavas) in Transylvania. I herewith rectify therefore my incorrect datum of 1965. Accordingly, Koeleria tenuipes (SCHUR) UJH. inhabits not only the SE but also theSW Carpathians. The exact data of the specimen are: A Budapesti M. Kir. Állami Vetőmagvizsgáló Állomás Növénygyűjteménye. Koeleria ciliata KERN. V. transsilvanica SCHUR! Comit. BLunyad. Retyezát.

Schedula Ujhelyii: Koeleria eriostachya PANC. Rev.: J. ÚJHELYI As is to be seen, neither Á. DEGEN nor K. DOMIN could possibly have seen Koeleria eriostachya PANÖ. in the Retyezát — it was my statement which was over hasty. The situation is different with the orther two specimens. The exemplar preserved in E. J. NYÁRÁDY'S herbarium has the following data: Herbarium E. J. NYÁRÁDY Koeleria pyramidata (LAM.) DOMIN var. hirsuta CSŰRÖS V. n. "superficie glumellae, praecipue carena hirsuta" in Contributia Botanic 1962 (1963) p. 148, fig. 2. p. 145. Albele havas sziklafalain a Retyezáttól délre. 30. VH. 16. 1956. leg. St. CSŰRÖS. NYÁRÁDY also ecnlosed a precise figure of the cross-section of the leaf. The innovational leaves of the 75 cm high robust plant attain a length of 30 cm. Panicle 12 cm long, cyhndrical, 1.2 cm thick. Spikelet 8-9 cm long, aristulate, hirsute. Culm densely puberulous below panicle. Senile leaves of innovation evenly hirsute, marginally ciliate (these cilia much smaller than in Koeleria mollis MANN). Juvenile blades glabrescent, marginally more minutely ciliate or scabrous, their vetust vaginae sericeous with appressed hairs. Panicle (of S. PAP'S specimen) more compact, denselv hirsute. — These characteristics are not enough to distinguish the plant as a variety of the nominate race. In 1966,1 journeyed to the Retyezát with the help of E. GY. NYÁRÁDY, Academician, with the aim to find Koeleria eriostachya PANÖ. Unfortunately, we could not find it. The plant differs principally by its stature from Koeleria mollis MANN ( = Koeleria pyramidata [LAM.] DOM. pro p.). Its long innovational leaves and the structure of the leaf epiderm reveal that we are confronted with a disjunct occurence of Koeleria eriostachya PANÖ. On the innovational leaves of Koeleria mollis MANN, living also in the Transylvanian Basin, the pili are twice longer and more robust than in our plant. The same holds also for the macro-hairs. Koeleria mollis MANN is not an alpine species, but a plant of the colline region.
