cent to each other, the latter are larger than in its progenitor; the intercostal zone is 4—6-seriate, generally with or without two stomatic cellular rows, the cells of the basic tissue alternate with macro-hairs, the stomata are bigger than in the preceding species; on the juvenile leaves the costal and intercostal zones are slightly indistinct, but never to a rate as in its preceding ally, the walls are strongly sinuous, the macro-hairs or their vestiges follow densely each other, they are larger, and scattered silica-bodies also appear (Plate III, Fig. 1, 2).

Regnuni Granatense, Sierra Nevada, in pascuis aridis in Dehesa de S. Garonimo 2000 m, 11. Julio (BP, 19 675, et Z, sub nomine Koeleria crassipes LANGE fl hisp. 1.74 ß vestita LANGE). The plant grows on dry subalpine pastures, 2000 m a. s. 1. in the Sierra Nevada, Granada. The basal leaves are velutino-pubescent, marginally with rare and long setae, the panicle is pale yellow, the spikelets glabrous, apically acuminate. Differing in these features from the nominate form, the plant otherwise is highly similar to the hexaploid Koeleria dasyphylla WILLK., inhabiting also the Sierra Nevada. The same holds for the epidermal structure of the basal leaves, but the measurements, in accordance with the tetraploid grade, are in all respects smaller. F. SCHUR

's Koeleria bivestita has an interesting history. The plant was described by F. SCHUR in 1859, in the ninth volume of the Österreichische Botanische Wochenblatt. Among others, he writes in his remarks as follows: "Von dieser niedlichen Koeleria kenne ich nur ein einzelnen Exemplar, unicum, welche ich in einem alten von Herrn Apotheker HORNUNC herstammenden Herbar vorfand, das aus der Umgegend von Kronstadt herstammen und von einem Herrn RITTER gesammelt sein soll

. . K. DOMIN also included the plant as a good species in his Monography; listing it in his Observatio between Koeleria caudata and Koeleria brevifolia. He, too, had already inferred the possibility of a mix-up in labels, but finally rejected it. He writes
