Rootstock nodo?e developing early the next season's young pointed shoots. L. 

 margin scabrous and ciliate with long rather rigid hairs (but these are seldom 

 seen in herbarium specimens), ligule short truncate. Rhachis with scabiid angles. 

 Lower spkts. sometimes reduced to empty glumes. Gl. i cymbiform strongly

2. A. tenella, Nees. 



A very elegant and delicate grass, 6-20" high, sometimes the whole 

 plant reduced to a large panicle with a single leaf. Glabrous. Leaves 

 from ovate- to linear-lanceolate 2-14" long, up to -6" broad, acuminate, 

 membranous. Panicle very large for the plant 2-10" long by nearly 

 as broad with long slender spreading branches and capillary branchlets 

 and pedicels. Spikelets minxxte innumerable, only -06" (exc. the 

 delicate awn of iv), on pedicels many times longer than themselves, 

 glabrous or sparsely hairy.

Stem glabrous or usually with few very delicate hairs. Leaf-sheaths rarely 

 hairy, ligule short hairy. Spikelets with their pedicels often in pairs on a 

 capillary peduncle. Gl. i ■Qi" 3-uerved ; ii longest finely acuminate 5-nerved ;

A stout often very tall grass attaining 15-20 ft. but usually much 

 smaller (unless the smaller kind is another species ?), from a stout 

 hard creeping rootstock. Leaves 6-18" by -17—9", with more or less 

 dense hairs inside towards the base which meet those of the ligule 

 and become indistinguishable from them. Panicle 6-20" with very 

 numerous fastigiate rigid, fascicled or subverticillate branches about 

 one-fourth as long as the main rhachis, usually simple and sulcate, 

 bearing more or less secund spikelets densely imbricate in several 

 series. fSpkts. lanceolate acuminate •14-'16" long, longer than their 

 pecUcels one of which is about -1", the other very short. Gl. i narrow

 paleate, male ; iv oblong-lanceolate -1" scaberulous with a terminal 

 caducous awn about -12" long, base of glume bearded or with few thin 

 hairs.
