D. Richard.“ — Paspalum minutum Trin. (Linnaea, 10; 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, Pittier 508 and Jimenez 146. 
42. Axonopus laxiflorus (Trin. A. Chase, 1l. c., p. 133. — Paspalum 
laxiflorum Trin., Mém. Acad. St. Pétersb., VI. Sci. Nat., 32; 148, 1834. 
»V. ssp. Bras.“ The type specimen, in the Trinius Herbarium, is la- 
beled „Paspalum laxiflorum m. In saxosis pratisque humidis S. da 
Lapa, Langsdorff.“ — This species is represented from North 
America in the National Herbarium by Pittier 214, Alta Verapaz, 
Guatemala, and Nelson 2738, collected between Guichocovi and La- 
gunas, Oaxaca, Mexico. 
43. Axonopus poiophyllus A. Chase, |. c., p. 133. — Plants perennial, 
tufted, flattened at the base; culms erect, slender, compressed, 60 to 
90 em high, simple, glabrous or minutely scabrous below the appressed- 
pubescent nodes, the leaves mosily crowded at the base; lower sheaths 
much overlapping, keeled, villous, the upper pubescent 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. 860024, 
collected in April, 1904, in the vicinity of Secanquim, Alta Verapaz, 
Guatemala, by O. 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.
