5G TRIANDRIA. MONOGYNIA. 



as long as the corolla. Corolla 2-valved, ob- 

 long-ovate, terete, and awnless. Style very long. 

 JVectary cleft. 



Spikes di,^itate, linear; flowers by pairs alternately sub- 

 sessile. Species o' Panicinn of Linnxus and others; with 

 which they nearly agree in structure, but possess the ha,- 

 hit of Paspali/m. 



Species. 1. D. sangiibiolis. 2. viUosa. S.Jiliformis. 4. 

 paspalodes. 



Except ilie D. sanguinaUs and the D. humifzisa of Eu- 

 rope, the few- other species of this genus, about 12, are 

 confined to India and North America. 



83. CYNODON. Richard, (Bermuda-grass.) 



Calix 2.valved, spreading, lanceolate. Co- 

 rolla larger than the calix, 2-valved; the exte- 

 rior valve large and ovoid. A^ectary truncate. 



Spikes digitate, flowers imbricated in a single series, 

 solitary. 



A remarkably creeping grass, growing very luxuriantly 



in the sands of the sea-coast, as well as the poorest loose 



soils, and were not its extirpation so diflicult, niight be 



of importance for forming pastures where scarcely any 



( other vegetable could exist. 



There is only 1 species, the C Dactvlon, common to 

 Europe, North America, and the "West India islands. 



84. PASPALUM. L. 



Calix 2-valved, equal, mostly orbicular. Co- 

 rolla 2-valved, of the same figure and magni- 

 tude. Stigma plumose. 



Flowers in digitate spikes arranged on one side; mostly 

 in 2, 3, or even 4 rows; rarely alternating in a single row, 

 in some species ovate as v.ell as orbicular. Spikes ge- 

 rerally digitate and definite, in a few species allied to the 

 genus Ceresia, y'lz. P. membranacewn {Cere sia Jluii cms oi 

 Mr. Elliott.) and ihe P. stoioniferinn, the spikes are very 

 numerous, and disposed almost verticillately upon a ra- 

 ceme, in these also the flowers are ovate, and the rachis 

 membranaceous. This genus, as Mr. Brown very justly ob- 

 serves, is closely allied to Fanicam, at least to the species 

 ivhich produce spikes.
