28. A. Schinzii, Hack, in DC. Monogr. Phan. vi. 458. Perennial, 
densely tufted, 2-4 ft. high. Culms erect, slender, glabrous, 
terete, simple and sometimes woody below, with barren solitary 
or fascicled branches from the lower nodes, and with few solitary 
(rarely 2-3-nate) leafy long and erect flowering branches higher 
up. Leaf-sheaths terete, tight, glabrous, firm, the lower and 
intermediate mostly longer than the internodes, shortly auricled 
at the mouth, the basal long, persistent ; ligules membranous, 
truncate, laterally produced and adnate to the auricles of the sheath, 
§-l lin. long ; blades linear from a slightly narrower base, long- 
tapering to a fine point, 4-8 in. by 2-3J lin., flat, rigid, glaucous, 
slightly rough or puberulous on both sides, rarely with some 
additional very long and fine spreading hairs, midrib whitish, rather 
slender, lateral primary nerves 3-4 on each side, very fine. In- 
florescence of the culms and their leafy branches reduced to a 
terminal raceme-pair or augmented by 1-2 distant simple 1-noded 
branches or 2-3-rayed tiers ; spathes subherbaceous, green, some- 
times faintly tinged with purple, at length tightly inrolled, with 
a more or less reduced blade ; rays filiform, erect, strict, up to over 
3 in. long. Spatheoles similar to the spathes, generally with an acute 
or setaceous point and up to 3 in. long ; peduncles at length long- 
exserted, straight or flexuous, terminating with a frequently bearded 
eupule. Racemes 2-nate, one sessile, the other with a short base, 2-3 
in. long, straight or flexuous, villous ; joints and pedicels equal or sub- 
equal, cuneate, stout above, much attenuated towards the base, 
2- 2 J lin. long, rigidly ciliate on both sides, cilia up to over 2 lin. long, 
tips obliquely cupular, minutely toothed. Sessile spikelets of all pairs 
heterogamous (except the lowest 1 or 2 of the sessile raceme — rarely 
also of the pedicelled — which are more or less reduced or $ and 
occasionally approach their pedicelled companions in shape), laterally 
compressed, loosely wedged in between joint and pedicel, narrowly 
linear in front view, 3-3J lin. long, glabrous ; callus short, obtuse, 
shortly bearded. Glumes somewhat unequal, the lower slightly 
shorter, subcoriaceous, dull green, with a deep narrow hyaline groove 
between the keels which are obtuse and smooth up to three-quarters, 
then acute and scaberulous,tips minutely 2-toothed, purplish, nerves 
4 on each side, one close to the groove, the others in the keels, green 
in transmitted light ; upper glume boat-shaped, submembranous, 
3- nerved, ciliate, with a terminal bristle up to 5 lin. long. Lower 
floret reduced to a linear-oblong acute 2-nerved ciliate hyaline valve
