repens HBK. as figured in Nov. Gen. PI. t. 52. These species 

 {Dinebra bromoides, D. repens and Boutelo2ia Humboldtiana) were 

 united under Bouteloua bromoides Lag. by S. Watson in Proc. 

 Amer. Acad. 1883, p. 177. Artstida Americana Sw., Obs. 41, t. 

 ii, f. 2 (1791), cited by Kunth, is an older synonym, the specific

56. Pappophorum mucronulatum Nees. ?=No. 350 E. 

 Palmer (1887). This may be only a form of P. alopecuroidewn 

 Vahl., but it differs from my West Indian specimens so ticketed, 

 and it does agree very well with Doell's figure and description of 

 P. mucronulatuvi. It is not P. apertum Munro, Scribn. in Bull. 

 Torr. Club, ix (1882) p. 52. The following are some of the char- 

 acters of the spikelets: Spikelets including the awns 11-12 

 mm. long, with usually two perfect flowers and two to three 

 empty glumes above. Lower empty glumes ovate lanceolate, 

 bristle-awned between the two unequal teeth at the apex, the 

 second about 5 mm. long, a little exceeding the first. Flowering 

 glumes broad and rounded on the back, about 3 mm. long to 

 base of awns, densely pilose on the short and obtuse callus and 

 on the midnerve below the middle and on the sides half way 

 up, pubescent on the inner face above, 7-nerved. Awns 12-15, 

 the longer ones 8-9 mm. diverging, violet-colored, strongly sca- 

 brous. The upper empty glumes with a villous tuft on the back 

 below the middle, sides and callus naked. — Guaymas Mexico, 

 November 7 (76).
