Pachilla thin- ly pubescent, about 3 mm. long. General distribution: Atka and Unalaska. Type in Herb. Le<lebour from Unalaska, collectetl by Eschscholtz. Specimens examined.—I'na- htska (W. H. Evans 550 in 1897; Dr. A. Kellogg 142 in 1867; S. Applegate, no number or date; M. W. Harrington in 1871-72). AtJ:a (L. M. Turner 1194 in 1880). This species is very closely related to B. marginatus. The <jriginal description says "spikes glabrous," ])ut we have amended it to include forms having scabrous-pubescent flow- ering glumes. Such forms coming from St. Petersburg Herb, and evidently determined by Trinius are in the Gray Herb. We have seen no speci- mens witli i^erfectly glabrous spikelets. 34. BROMUS SITCHENSIS Bong. Obs.
