Axonopus deludens Chase, Proc. Biol. Soc. Wash. 24: 134. 1911. 
A smooth and glabrous tufted perennial, with a creeping rootstock, long flat leaf-blades, 
and a long-exserted panicle of slender racemes. Stems up to 1.5 m. tall; leaf-sheaths com- 
pressed; blades up to 4.5 dm. long and 1.5 cm. wide, long-acuminate; racemes 6-15, slender, 
the rachis triangular and barely winged, scabrous on the margins, 1.5—2 dm. long, sometimes 
naked at the base; spikelets rather scattered, sometimes barely overlapping, about 3 mm. long, 
the scales about equal in length, the outer two 5-nerved, or 4-nerved by the suppression of the 
midnerve, the fruiting scale oblong-elliptic, obtuse, rough with papillae, glabrous, or with a 
few hairs at the apex.

A tufted perennial. Stems erect, up to 1 m. tall, sometimes with one or more leafless 
branches from the upper axils; leaf-sheaths ciliate on the margin, glabrous or pubescent; 
blades up to 2 dm. long, 3-4 mm. wide, commonly folded, glabrous, or the upper surface 
somewhat hairy, sometimes ciliate toward the base; racemes 3-7, 3-12 cm. long, sometimes 
only 2 or 3 and digitate, the others when present scattered below; spikelets 2.5 mm. long, the 
scales about equal in length, the outer ones pubescent with Jong hairs, usually 4- or 6-nerved by 
the suppression of the midnerve, the fruiting scale elliptic-oblong, obtuse, with u tuft of hairs 
at the apex. 
TYPE LOCALITY : Brazil. . ; 
DISTRIBUTION: Oaxaca to Guatemala; alsoin Brazil. 
7. Anastrophus poiophyllus (Chase) Nash. 
Axonopus potophyllus Chase, Proc. Biol. Soc. Wash. 24: 133. 1911. 
A tufted perennial. Stems erect, slender, compressed, up to 1 m. tail, the nodes appressed- 
pubescent; lower leaf-sheaths villous, the upper ones glabrous or pubescent along the margin; 
blades up to 3.5 dm. long, 3-5 mm. wide, firm, erect, linear, folded at the base and boat-shaped 
at the apex, papillose-villous toward the base; racemes about 3, slender, erect, up to 12 cm. 
long; spikelets rather distant, about 3 mm. long, flushed with purple, oblong-elliptic, the 
outer scales a little longer than the fruiting scale, sparsely pubescent at the base and on the 
margins, 4-nerved by the suppression of the midnerve, the fruiting scale with a tuft of hairs 
at the apex. 
TYPE LOCALITY : Secanquin, Alta Verapaz, Guatemala. 
DISTRIBUTION : Known only from the type locality.

A tufted perennial. Stems up to 6 dm. long, slender; leaf-sheaths rough; blades linear, 
acute, flat or folded, 2-3 mm. wide, the basal up to 3 dm. long, those on the stem shorter; 
racemes in pairs, or sometimes with an additional one a short distance below, 5-7 em. long; 
spikelets 4 mm. long, acute, lanceolate, the outer scales equal, lanceolate, acuminate, 5-nerved, 
sparingly hairy, the fruiting scale oblong, obtuse, about 3 mm. long, with a tuft of short hairs 
at the apex.
