The data of the other specimen are : K. pyramidata glaberima m. No 7. Mte CampioneanSiguetta?c. 1500 m. Massif delà Grigna sur Lecco, Lombardia, VII. 1902. leg. WILCZEK, H. L., Herbarium K. DOMIN. duplication cum scripta K. DOMINI (PRC). The specimen is rather incomplete. The anatomical structure of the wholly glabrous plant resembles that of Koeleria borbasii UJH., but it is in no case identical with it. I examined four specimens of 8. var, rigidiuscula DOMIN; all of them belongto Koeleria mollis MANN. Their panicles are densely compact (the pedicels very short), owing to their anthocyanine content they are violaceous, the innovational leaves rigid and short. The undersides of the blades are characterized by the short hairs — hence the leaves appear to be glabrous — but they still allow to distinguish among them the primordia of the macro-hairs and the bases of the pili ; the costal zone is also 1 -2(3)-seriate, and the leaf-margins show erect pili (Plate I, Fig. 1, Pl. II. Fig. 1). The new name of the plant is. Koeleria mollis MANN var. rigidiuscula (DÓM.) ÚJHELYI comb, nova Specimina examinata: A. KNECGKER: Gramineae exsiecatae. XVII. Lieferung. 1905. INr. 505.

Pflanze von v. rigidiuscula durch längere Blätter und die stärkere Behaarung und von typischen pyramidata durch strafferen Wuchs und schmalere Blätter, durch die gefärbten und dichten Rispen unterscheide. Die Halme erinnerten in der stärkeren Behaarung an die var. pubiculmis DOM. Die typische pyramidata habe meist eine große, gelappte, nicht dichte, blasse oder nur schwachen gefärbte Rispe. A. K.

I saw one specimen of 9. var. taxa DOMIN; its data are: pyramidata v. taxa. Flora Genevensis: Bois des Frères, 22, Juin. 1856, leg.: J. C. DucoMMUN, duplicatum ab H. L., Herbarium K. DOMIN (PRC). Also this specimen represents Koeleria mollis MANN. Another European plant described as distinct in the Cristatae verae. Robustae is Koeleria genevensis DOMIN, given as a distinct, so-called great-species in DOMIN'S monograph (1907). A duplicate specimen in DOMIN'S herbarium carries the following data : Koeleria genevensis n. sp. Flora genevensis. Koel. crist. var. Mt. Reculet (Jura), 22, Juület 1860, leg.: J. C. DUCOMMUN mit K. pyramidata H. L. (PRC). The plant of the herbaria! sheet had. judged by its stature, grown in a rather arid locality. The anatomical structure of the innovational leaves at once reveals that we have to do with Koeleria mollis MANN again. According to K. DOMIN'S remark, he saw

r several specimens in the Herbarium at Lausanne. Its description as a distinct species springs principally from his points of view. He had presumably overestimated the features of its habit. The panicles of the comparatively stout plant are very compact, the spicules obtusely pointed and with a golden sheen. These characteristics might have induced the author to consider the plant a distinct species in accordance with his views.
