Culms up to $1° tall, sparingly branched above; blades erect, firm, usually somewhat glaucous, long-acuminate, the lower 8'-i2' long and 2i"-3i" wide; racemes in pairs, a's' long, the rachis internodes glabrous, or the margins with a few long weak crimped hairs; sessile spike- lets lanceolate, about 5" long, acuminate, the first scale sulcate on the back, the intercarinal space 2-nerved, the fourth scale with an imperfect awn less than i its length; pedicellate spikelets stami- nate, a little smaller than the sessile ones, the first scale g-nerved, not sulcate, the pedicels sparsely pilose with long weak crimped hairs. In sand, Nebraska and Montana. Summer and fall. 7. AMPHILOPHIS Nash, in Britton, Man. 71. 1901. Perennial grasses with usually flat leaf-blades and showy, often silvery white, panicles, the axis short or elongated. Racemes usually numerous, the internodes of the rachis and the pedicels with manifestly thickened margins, the median portion thin and translucent, the margins ciliate with long hairs. Spikelets dorsally compressed. Sessile spikelets of 4 scales, perfect, or rarely the lower pair or pairs staminate or empty; first scale 2-keeled, the margins narrowly inrolled; second scale i-nerved; fourth scale stipe- like, the blade wanting, merging into a usually geniculate perfect, rarely imperfect, awn, or the awn rarely wanting. Pedicellate spikelets awnless, staminate and similar to the sessile ones, or empty and smaller than them. Stamens 3. Styles distinct. Stigmas plumose. [Greek, in reference to the hairs surrounding the spikelets.] A genus of about 15 specie
