Vallesia: Kt. Neuchatel: Hochmoor bei La Brevine lg. SCHROETER there is a spikelet, while the data of the duplicate specimen of var. 2. glabriglumis DOMIN are : Vallesia: Kt. Neuchatel: in Monte Creux du Vent, leg. JEANJAQUET, 23. Juin 49. H. Pol. Zürich. The plant is 15 cm high, a single shoot with a 3 cm long panicle, its innovational senile blade 2 cm long and 1 mm wide, the juvenile leaf 5 cm long and 1 mm wide. In the herbarial material of the Botanical Museum of the University of Zürich, I found four sheets of Koeleria under diverse names ; three of them have a diploid character and originated from the Obere Reusstal, Schwizerland. Their panicle are similar to that of SCHROETER'S exemplar. The fourth specimen was collected by FR. HÉRIBAUD in Cantal, France ; it is without doubt an octoploid grade plant, its stature, growth, form of panicle all differing from those of the previous three. The structure of the leaf epiderm of the diploid grade specimens agrees with that of Domin's 2. var glabriglumis DOM. These two plants also represent a member of the Series Arenariae UJH., and are wholly unrelated with Koeleria eriostachy PANC. This diploid grade plant is not the subspecies of Koeleria, eriostachy PANC., but a distinct species of the Series Arenariae UJH. 52. Koeleria schroeteriana (DÓM.) ÚJHELYI sp. n.
