at the top, with a broad membranous edge. The lower glume only % as long, 1-nerved. 

 The pales are surrounded by a tuft of hairs at the base, the lower one 4-nerved, some- 

 what roughly dotted, bicuspidate or slightly tattered at the top, about the middle fur- 

 nished with a long rough, geniculate awn projecting 12 to 13 mm. beyond the apex of 

 the pale itself. The upper pale is slightly 2-nerved, 2-toothed at the apex, of the same 

 length as the outer one. 



Thus, this form is especially characteristic in having a narrow, few-flowered panicle, 

 always with unramified branches reduced to pedicels. The upper glume is generally so 

 large as to enclose the spikelet completely. 



This variety may possibly have a greater systematic value; however, this question 

 must be left undecided, as my material is too scarce to enable me to try the value of the 

 various characters. Gathered in thickets near Kushabar, in full flower at the end of 

 July. 



Distribution: The species Avena pubescens is distributed over Europe, except the 

 extreme northern and south-western portions, Caucasia, Asia Minor, south-western and 

 western Asia, Siberia eastwards to Trans Baikal.
