Stem 1-2 ft., very slender, geriicnlately ascending from a creeping base. Leaves 

 1_3 by -|- in., elliptic-lanceolate, acute and apieulate, very thin, flaccid, base 

 narrowed; ligule short, hyaline, lacerate. Panicle 6-8 in., very slender; spikes 

 capillary, 2-3 in. Spikelets about -^ in. ; nerves of gl. Ill and palea fringed with 

 long hairs. Grain not seen. Judging from Burmann's figure of the leaf his Poa

Stems erect, 2-3 ft., stout or slender, sometimes proliferously branched below ; 

 lower nodes glabrous or bearded. Leaves 1218 in., convolute, rarely flat, ficely 

 acuminate. Panicle 6-10 iu., flexuous ; branches filiform. Spikelets ^ in., close- 

 set, pale; gls. I and II unequal, ovate-lanceolate, rather longer than III, pale 

 green; 111 broadly ovate, subacute, 3-nerved, nerves and keels of palea ciliate. 

 Grain oblong, deeply grooved on one side. The form of the panicle differs much from 

 that of the following ; but the spikelets and glumes are very much alike. L. poty' 

 stachya, Kunth, an American plant, is a species of Diplachne,

Stem 1-2 ft., slender, geuioulately ascending. Leaves. 4-10 in., flat, flaccid, 

 finely acuminate; ligule short. Panicle 4-8 in., contracted or diffuse, branches very 

 many almost capillary ; spikelets -^ in., gl. I and II oblong-lanceolate, acute; III 

 and i V broadly ovate, nerves and palea ciliate. Grain oblong, closely invested with the 

 gl. and palea. I have followed my predecessors in referring this Indian grass to 

 Leptochloa filiformis, 11. & S., though that plant is described as American, and as 

 having glabrous flowers ; a character apparently confirmed by Jacquin's drawing of 

 its synonym Eleusinejilifnrmis, Pers. (Jaeq. Edk>g. Gram. t. iv.) and by an observa- 

 tion of Doell in Mart. FJ. Bras, ii III. 93. Ou the other hand, I find the nerves of 

 gl. Ill to be invariably hairy in American specimens corresponding with Jacquin's 

 pLite and the description of L. jilifurmis, and hence must suspect that this very 

 inconspicuous character (except under a good magnifying power) has been overlooked.
