44. Axonopus deludens A. Chase, |. c., p. 134. — Plants perennial; 
eulms geniculate at base, leafy, strongly flattened, rather stout, 1 to 
1,5 meters high, sparingly branching, glabrous, the nodes glabrous; 
sheaths glabrous or minutely pubescent at the summit; ligule about 
0,5 mm long, membranaceous, erose; blades rather thin and lax, linear, 
15 to 45 cm long, 8 to 13 mm wide, flat, sparsely papillose-scabrous on 
the upper surface and on the margin, pubescent on the narrow auricles, 
glabrous beneath, the midnerve prominent; inflorescence of 6 to 15 very 
slender, erect or rather lax racemes, 10 to 25 cm long, the lower mostly 
naked at the base, the rachis narrow, subflexuous, scabrous; spikelets 
purple tinged, distant about their own length or, toward the base of 
the raceme, remote, 3 to 3,2 mm long, 1 to 1,2 mm wide, obtuse, gla- 
brous, the second glume and sterile lemma covering the fruit but not 
exceeding it, delicate in texture, 4- or 5-nerved, the midnerve present or 
suppressed even in adjacent spikelets, the lateral nerves strong; fruit 
papillose, smooth toward the summit and margins of the lemma, the 
apex glabrous or with a few obscure hairs. — Type U. S. National 
Herbarium no. 460803, collected Oct. 20, 1903, Barranca near Guadala- 
jara, Jalisco, Mexico, by C. G. Pringle (no. 8761). — This species 
is not closely related to any other we have seen. The geniculate lower 
nodes suggest a stoloniferous habit, but our one specimen does not show 
stolons, The suppression of the midnerve in the glume or its presence 
is somewhat confusing, since it gives the impression of spikelets turned 
different ways, reserve and obverse, but turning back the glume always 
shows the back of the fertile lemma turned from the axis. 
45. Axonopus chrysoblepharis (Lag.) A. Chase, l. c., p. 134. — Ca- 
brera chrysoblepharis Lag., Gen. & Sp., Nov. 5, 1816. (See above under 
Cabrera.) — Paspalus immersus Nees, Agrost. Bras., 82, 1829. „Habitat 
in campis ultra 2000 pedes altis provinciae Minarum generalium pas- 
sim.“ The type specimen was examined in the Munich Herbarium. 
This is, as Nees indicates, the species Kunth called Paspalum aureum, 
but since Kunth based this name on Axonopus aureus Beauv., his name 
is a synonym of that, misapplied to this species. — Panicum immersum 
Trin., Mém. Acad. St, Petersb., VI, Sci. Nat., 32; 197, 1834. Based on 
Paspalum immersum Nees. — Panicum chrysoblephare Steud., Syn. Pl.

Boruca and Terraba, by Pittier; no. 11004 of the same series, collected
