432 GR AMINES. [Era^rostis. 



narrow, but flat. Panicle oblong, usually 2 or 3 in., but sometimes twice as 

 long, with numerous short slender branches. Spikelets all pedicellate, usually 

 drooping, ovate, about 1 line long, 4- to 6 -flowered, the axis more or less ar- 

 ticulate. Glumes rather pointed, especially the lower ones. Paleas ciliate on 

 the ribs, with rather long spreading hairs, often persistent in the lower part 

 of the spikelet. — Foa pluniosa, Retz ; Kunth, Enum. i. 338. Poa amabiUs, 

 Linn. Spec. 100 (and Herbarium). 



Hougkong, Hance, Harland, Wright. Common in tropical Asia. 



3. E. pilosa. Beam. ; Steud. Spi. Gram. 263. A tufted erect or ascend- 

 ing annual, 1 to near 2 ft. high. Leaves narrow. Panicles 6 in. to 1 ft. 

 long, narrow at first, spreading when in fruit, compound, with numerous fili- 

 fonn branches alternate or clustered, and generally with a few long hairs in 

 their axils. Spikelets linear, about 2 lines long, wdth 6 to 10 flowers loosely 

 alternate on a zigzag inarticulate axis. Glumes thin, keeled, rather pointed, 

 the 2 outer empty ones unequal, but both smaller than the flowering ones. 

 Paleas often persistent, slightly ciliate on the ribs. — Poa pilosa, Linn.; Kunth, 

 Enum. i. 329. P. vertlcillata, Cav. ; Kunth, 1. c. 



Hongkong, Hance. A common weed in southern Europe, northern Africa, central Asia, 

 and some parts of north and south America. 



4. E. unioloides, Nees ; Steud. Syn. Gram. 264. Stems tufted and 

 erect, 6 in. to 1 ft. high or more. Leaves rather narrow. Panicle 3 to 6 in. 

 long, more or less spreading ; the branches slender, but short and little divided. 

 Spikelets ovate or ovate-lanceolate, veiy flat, with 16 to 20 or even more 

 flowering glumes very regidarly and closely distichous. Outer empty glumes 

 narrower, but fully as long and more pointed. — E. amabilis, W. and Arn. ; 

 Nees, PL Meyen. 205. Poa unioloides, Eetz; Kunth, Enum. i. 335. 



Hongkong, Hance, Harland. Common in dry situations in India, from Ceylon and the 

 Peninsula to the Archipelago, and northward to the Philippines and S. China. 



5. E. pilosissixna. Link; Steud. Syn. Gram. 280. Very near the E. 

 orientalis, but the panicle is more spreading, the pedicels longer and more 

 slender, and the leaves flatter, and covered as weU as their sheaths with long 

 soft hairs. — Poa pilosissima, Kunth, Enum. i. 330. Eragr. Millettii, Nees, 

 PI. Meyen. 206. 



Hongkong, Harland. Also on the adjacent continent, but not known for certain out of 

 S. China, 



6. E. orientalis^ Trhi. ; Nees, PI. Meyen. 205. Stems rather slender, 

 erect, ^ to 1^ ft. high. Leaves very narrow, glabrous, convolute when diy, 

 rather short. Panicle spreading, 3 or 4 in. long, but little branched. Spike- 

 lets pedicellate, oblong-linear, 2 to 3 lines long, about f line iDroad, with 8 to 

 20 or even more flowers, not very closely imbricated, on a zigzag continuous 

 axis. Glumes firm, the flowering ones very obtuse, the outer empty ones 

 rather shorter and scarcely more pointed. 



Hongkong, Wright, Hance. Also on the adjacent continent and in northern India. It 

 is very nearly allied to the E. foaoides, Beauv., a common species in southern Europe and 

 central Asia. 



7. E. Brownei, Nees; Steud. Syn. Gram. 279. Closely allied to the 

 E. orientalis, and perhaps a variety. The panicle is not so loose, the pedicels 

 shorter, the spikelets flatter and broader, usually about 3 lines long and 1 line
