This plant has no very close relatives among the previously described species 
reported from Central America, unless it may be Achyranthes pycnantha (Benth.) 
Standley. In that the sepals are densely long-pilose and 6 to 7 mm. long, the leaves 
are nearly glabrous, and the peduncles are usually branched. 
Achyranthes stenophylla Standley, sp. nov. 
Stems slender, branched, the branches ascending or suberect, striate, very sparsely 
pilose or glabrate; leaves numerous, the internodes short, the petioles 2 to 10 mm. long; 
leaf blades linear to elliptic-linear, 2.5 to 5 em. long, 3 to6 mm, wide, acute or acutish, 
acuminate at the base, very sparsely appressed-pilose or glabrate; peduncles axillary, 
simple, 2 to 5 cm. long, short-pilose, very slender; spikes ovoid or short-cylindric, 
6 to 10 mm. long,6 mm. thick; bracts broadly ovate, acute, glabrous: bractlets half as 
long as the sepals, acuminate, long-aristate, sparsely short-villous; sepals lance-oblong, 
2.5 mm. long, acute or acutish, membranaceous, 3-nerved, sparsely short-pilose, 
stramineous, the tips erect or slightly incurved; filaments short, the staminodia 
ligulate, longer than the anthers, two-thirds as long as the sepals, lacerate at the apex; 
style evident, the stigma entire. 
Type in the Herbarium of Columbia College (New York Botanical Garden), col- 
lected in Panama by Sutton Hayes (no. 941). 
This plant belongs to the same group as A. pycnantha, A. williamsii, and A. cordo- 
bensis, but it is very distinct from all of them in its smaller spikes and very narrow 
leaves. 
Achyranthes laguroides Standley, sp. nov. 
Erect or ascending, suffruticose below, the stems 1 meter long or less, much branched, 
the branches striate, sparsely pilose-strigose or glabrate; leaves very shortly petiolate, 
the blades narrowly lanceolate to elliptic-linear, 1.5 to 5.5 cm. long, 2 to 6 mm. wide, 
acuminate or attenuate at both ends, pilose-sericeous, densely so beneath; peduncles 
simple or branched, 5 to 20 mm. long, or the heads often sessile or subsessile, the pedun- 
cles densely pilose-sericeous; spikes ovoid or short-cylindric, 1 to 2 em. long, 9 mm. 
thick, the flowers whitish-stramineous; bracts and bractlets ovate-triangular, half as 
long as the sepals, acuminate or long-acuminate, sparsely pilose or glabrate; sepals 
linear-oblong, 4 to 5 mm, long, acuminate, membranaceous, l-nerved, pilose near the 
base with straight erect jointed white hairs, these equaling or slightly exceeding the 
sepals; stamen tube elongate, the antheriferous lobes short; staminodia ligulate, 
exceeding the anthers, deeply and acutely laciniate at the apex; style elongate. 
Type in the U. 8. National Herbarium, no. 471849, collected near San Francisco de 
Guadalupe, Costa Rica, May, 1893, by A. Tonduz (Inst. Fis. Geogr. Costa Rica no, 
8006). There is a specimen of the same plant in the herbarium of the Missouri Botan- 
ical Garden, collected somewhere in Costa Rica in April, 1910, by G. C. Worthen. 
The species is a very distinct one. It is to be placed nearest Achyranthes stenophylla, 
but that has flowers only half as large and sparsely short-pilose sepals, 
Achyranthes cordobensis Standley, sp, nov. 
Plants much branched, the branches spreading, loosely short-pilose, or glabrate in 
age; petioles 1 to 3 mm. long; leaf blades ovate-oblong or oval, or the uppermost 
lance-oblong, 3 to 6 cm. long, 8 to 20 mm. wide, rather abruptly long-acuminate, 
obtuse at the base, thin, densely pilose-sericeous beneath, less densely so on the upper 
surface; peduncles simple, axillary, 2 to 6 cm. long, pilose with ascending hairs; 
spikes solitary, rarely sessile, ovoid or short-cylindric, 8 to 15 mm. long, 11 mm. thick;
