Rachis merely scabrous on the angles: outer scales less pubescent and with shorter

2. Monachne subglabra sp. nov. 
A tall somewhat branching grass with rather broad, flat leaf- 
blades. Stems 8-12 dm. long, glabrous, the nodes densely pu- 
bescent with short, spreading hairs: leaves numerous ; sheaths 
usually shorter than the internodes and much shorter than the 
blades, ciliate on the margins, the lower ones _papillose-hirsute 
between the nerves ; ligule a ring of short hairs; blades linear to 
lanceolate, flat, ascending, or the longer ones drooping, glabrous, 
very rough on the margins, long-acuminate at the apex, generally 
narrowed toward the base, 1-3 dm. long and 7-17 mm. wide: 
inflorescence finally somewhat exserted, the rachis hispidulous on 
the ridges: racemes ascending, commonly 6-10, the larger 4-6 
cm. long, the rachis hispidulous on the margins and more or less 
setiferous : spikelets on shorter pedicels which usually bear a few 
long hairs, 3.5 mm. long and about 1.3 mm. wide, elliptic to 
- ovate-lanceolate, acute, a short semicircular first scale usually pres- 
ent, the second and third scales about equal in length, acute, rather 
sparingly pubescent with appressed hairs, 5-nerved, the third scale 
bearing in its axil a palet of equal length and a staminate flower, 
the fourth scale about three fourths as long as the spikelet, elliptic, 
mucronate, finely transverse-rugose.
