*hort, ciliatc. Panicle long, loose, much branched ; branches diffuse* very slen- 

 der, scabrous, nodose but Dot pilose at base. Spikelets mostly 3-flowered, soxnl 

 timos 5-flowered, solitary, on long capillary peduncles. Glumes nearly equal, 



lanceolate, acute, scabrous on the keel. Lotcer palea lance-ovate, acute, 3- nerved, 

 scabrous on the keel ; upper palcu shorter, obtuse, emarginate, arched, or curved 

 towards the lower one, scabrous on both keels. Seed oval, gibbous at base, red-

Obs. We have al80 t on the Mica-slate lulls, the P. tenuis, of Elliott,—*, plant at 

 large as P. hirsuta % — with Long radical leaves, sheaths pilose along the margin, a 

 very targe, spreading, capillary panicle, and spikelets l to 3-flowered ; which, how- 

 ever] Dr. Pickering thinks is not specifically ditt act. If not a distinct species, \\ 

 certainly constitutes a very striking Variety. 



9. P. itirsuta, Jtfx. Culm simple; panicle very largo, much branch- 

 ed ; branches expanding, at length divaricate, bearded in the axils ; spike- 

 lets pedunculate, oblong, 5 to 8-flowered ; upper palea ciliatc on the two 

 keels. Beck, Bot. p. 411, Spbcim. Gray, Gram. 1. no. 51.

Hirsute Poa. 



Root annual ? Culm stout, 1 to 2 feet high, mostly .simple and smooth. Leave* 

 long, lanceolate, attenuate at the. end, Btrongly nerved, smooth beneath, scabrous 

 on the margins and upper surface, pilo.se near the base: sheaths striate, loose, 

 longer than the joints, lower ones hairy, upper ones smooth ; liguU densely beard- 

 ed. Panicle $ to \o inches long, much branched, expanding; branches slender, 

 scabrous, pilose In the axils, the main ones nodose at base, divaricate when old. 

 Spikelets purple » lance-oblong, on long peduncles. Glumes nearly equal, ovate 

 lanceolate, acute, scabrous on the keel. Loicer juilea ovate, acute, 3-nerved, 

 roughish pubescent ; upjter palea linear-lanceolate, conduplicate, conspicuously 

 ciliatc on the two keels. Seed minute, purple. 



Nab. Sterile, sandy fields, road-sides, &c. frequent. Fl. August. Fr. Sept. 



Obs. With us, the culm and upper sheaths of this plant arc quite smooth: But 

 I have a Southern specimen, in which the sheaths, leaves, culm, and even the 

 branches of the panicle, are remarkably pilose. 1 have no doubt our plant is the 

 P. spectabilis, of Pursh : but I incline to think the P. refracta, Mold, and Elliott, 

 (which Dr. Torre y makes a Synonym,) may be a distinct species. I have received 

 specimens, from my friend .Mr. Curtis, of N. Carolina, which agree exactly with 

 EllioWs figure and description of P. refracta ;— the spikelets being linear-lanceu- 

 •late,subsessile, and racemose on the capillary branches. 



10. P. pilosa, L. Culm cespitose, oblique, geniculate at base ; sheaths 

 pilose at throat; panicle capillary, pyramidal, the lower branches pilose 

 in the axils; spikelets lance-linear, 5 to 12-flowercd ; glumes very un- 

 equal ; upper palea persistent. MuhL Gram. p. 141. Specim. Gray,
