GRAMINE^. 



Phalaris angusta, Nces ; Trin. Ic. Gram. t. 78 ; Kunth, Gram. 2, p. 32. 

 P. occidentalis, Nutt., in Trans. Amer. Phil. Soc. (n. ser.) 5, p. 144. On 

 Cache Creek ; May 16. This plant is certainly P. angusta of Trinius, of 

 which I have specimens named by that distinguished botanist. It appears, 

 however, scarcely to differ from P. microstaclya, DC. 



Paspalum ljeve, Michx. Fl. 1, p. 44 ; Trin. Panic. Gen., p. 160 ; Torr., Fl. 

 N. York, 2, p. 421. Main Fork of Red River ; June. 



Panictjm pauciflorum, Ell. Sk. 1, p. 120 ; Gray, Bot. N. States, p. 613. 

 Headwaters of the Trinity ; May. 



P. reticulatum, (n. sp.;) culmo geniculate erecto subsimplici ; foliis vagin- 

 isque laxe pilosis : panicula oblonga contracta, ramulis racemosis paucifloris ; 

 spiculis obovatis acutiusculis glabris breviter pedicellatis muticis ; glumis valde 

 inEequalibus ; flore neutro bivalvi ; palea inferiore (ut in gluma superiora) 

 7-costulata reticulata, flore hermaphrodito transverse ruguloso. On the Main 

 Fork of Red River; July. Nos, 2090 and 2091, Wright's Coll. N. Mex. 

 1851-52, are glabrous and more robust forms of this species. 



P. obtusum, (H. B. K. ?) spicis 5-7 racemosim dispositis erectis ; spiculis 

 geminis subimbricatis unilateralibus muticis obovatis obtusis glabris ; glumis 

 sequalibus multinervosis ; flore inferiore triandro bipaleaceo ; flore hermaphro- 

 dito subtilissime longitudinaliter striate subnitido.— H. B. and Kunth, Nov. 

 Gen. 1, p. 98? Tributaries of the Washita. Plant glabrous and glaucous, 

 about 18 inches long. Rachis narrowly linear, very flexuous ; nerves of the 

 glumes green. Near P. obtusum, H. B. K., but differs in the nearly equal 

 glumes, &c. No. 2092 Wright's Coll. N. Mex. 1851-52, is exactly our 

 plant.
