Pedro Paulo and San Blascito, L995 .1. X. Rose, August 4, L897." The 

 type specimen is in the National Herbarium. 



Axonopus papillaris (Lam.). 



Paspalum capillnre Lam. Tabl. Encycl. 1 : 176. 1791. "Ex America 

 merid. Comm. D. Richard." 



Paspalum minutum Trin. (Linnaea LO : 293. 1836), the type of which, 

 collected by Poeppig in Peru, was examined in the Trinius Herbarium, 

 appears to be based on depauperate specimens of A. capillaris. 



The only North American specimens we have seen of this species are 

 from Costa Rica, Pvttier 508 and Jimenez L46. 



Axonopus laxiflorus (Trin. ). 



Paspalum laxiflorum Trin. Mem. Acad. St. Petersb. VI. Sci. Nat. 3 2 : 

 14S. 1834. "V. spp. Bras." The type specimen, in the Trinius Her- 

 barium, is labeled " Paspalum laxiflorum m. In saxosis pratisque humidis 

 S. da Lapa. Langsdorff." 



This species is represented from North America in the National Her- 

 barium by Pittier 214, Alta Verapaz, Guatemala, and Xelson 273S, col- 

 lected between Guichocovi and Lagunas, Oaxaca, Mexico. 



Axonopus poiophyllus sp. now 



Plants perennial, tufted, flattened at the base; culms erect, slender, 

 compressed, 60 to 90 cm. high, simple, glabrous or minutely scrabrous 

 below the appressed-pubescent nodes, the leaves mostly crowded at the 

 base; lower sheaths much overlapping, keeled, villous, the upper pubes- 

 cent along the margin, otherwise glabrous or minutely pubescent; ligule 

 scarcely 0.5 mm. long, erose-ciliate ; blades erect, firm, linear, 8 to 35 

 cm. long (the uppermost reduced to 0.5 to 2 cm. long), 3 to 5 mm. wide, 

 the apex boat-shaped as in Poa, the lower conduplicate at base and 

 slightly narrower than the summit of the sheaths, usually flat above, 

 papillose-villous toward the base on both surfaces, scabrous on the upper 

 surface; inflorescence of about 3 slender, erect racemes, 6 to 12 cm. long, 

 the rachis narrow, flexuous, glabrous or minutely scabrous; spikelets 

 tinged with rose-purple, distant their own length, 3 mm. long, 1 mm. 

 wide, oblong-elliptic, subacute, the second glume and sterile lemma 

 slightly exceeding the fruit, minutely pubescent at the base and along 

 the edges with appressed silky hairs, 4-nerved, the midnerve suppressed 

 or nearly so, especially that of the glume, the lateral nerves near the 

 margins and approximate; fruit pale, very obscurely papillose, the lemma 

 with a minute tuft of erect hairs at the apex. 



Type U. S. National Herbarium no. S60024, collected in April, 1904, in 

 the vicinity of Secanqufm, Alta Verapaz, Guatemala, by 0. F. Cook & 

 C. B. Doyle (no. 58). 



This species is related to the group of cespitose South American species 

 to which A. laxiflorus also belongs.
