or less from the base ; culm leaves 2 ; sheaths loosely embracin 

 the culm, the lower, as well as those on the innovations, somewhat 

 hirsute with ascending-appressed hairs, the upper sheath 4 dm. 

 or less long, smooth and glabrous, or sparingly hirsute at the 

 base ; ligule a membranous ring about 2 mm. long ; blades 2 mm. 

 or less wide, smooth on the lower surface, rough on the upper 

 and more or less hairy at the very base, those on the innovations 

 3-4 dm. long, the upper culm leaf 1.5 dm. or less long; panicle 

 long-exserted, the axis 3-6 cm. long ; racemes 2, or rarely 3, 

 about 3 dm. long, erect, the rachis 3-angled, the angles hispidulous 

 and not winged ; spikelets slightly exceeding 2 mm. in length, 

 about .8 mm. broad, elliptic, acute, in 2's-4's, usually in 3's, 

 irregularly scattered, the hispidulous 3-angled pedicels of vary- 

 ing length united at the base, the short united portion mi- 

 nutely pubescent ; scales glabrous, the first wanting, the second 

 and third white, membranous, the former one-half or less as long 

 as the spikelet, usually one-quarter as long, 3-nerved, rounded 

 or truncate at the apex, the latter 5-nerved, acute, slightly shorter 

 than the spikelet, the fourth scale indurated and of a deep seal 

 brown when mature, conspicuously longitudinally striate, obtusely 

 angled on the back, the apex apiculate ; palet of equal length and 

 similar texture; grain white, elliptic-oblong, about 1.5 mm. long.

5. Syntherisma Bakeri sp. no v. 



Culms tufted, 1 metre or less tall, simple, erect, slender, the 

 innovations about one-half as long ; node 1 ; culm leaf 1 ; sheath 

 somewhat compressed, usually longer than the internodes, densel; 

 hirsute with ascending hairs, the upper sheath much elongated and 

 glabrous toward the summit, the sheaths of the innovations shorter 

 and crowded ; ligule a scarious ring about I mm. long ; blades 2 

 mm. or less wide, involute when dry, smooth on both surfaces, gla- 

 brous beneath, also above excepting at the very base where they are 

 densely pubescent with long hairs, those on the innovations 2-4 

 dm. long, on the culms 1-2.5 dm. in length ; panicle longexserted 

 the axis 4-7 cm. long, angled, the angles hispidulous ; raceme 

 usually 3, sometimes 2, commonly somewhat branched at the 

 base, erect or nearly so, densely long-pilose at the base, 14- 22 

 cm. long, the rachis 3-angled, the angles not winded but stron }' 



hispidulous: spikelets about 2.25 mm. long, .8 mm. wide, ellip- 

 tic, usually in 3's, on successively longer pedicels which are 3" 

 angled, the angles strongly hispidulous ; first scale wanting, the
