by twos or threes at tips of branches, densely short-hispid-pilose and vis- 

 cid; primary bracts unifoliolate, densely tuberculate-hispidulous and some- 

 what hispid-pilose, viscid, the rather broad sheaths 4 to 6.5 mm. long, 

 the triangular cuspidate-mucronate teeth 3 to 4.5 mm. long, the petiolulate 

 elliptic leaflet 6 mm. long or less; secondary bract 1, 4 to 4.5 mm. long, 

 bifid, ciliate above, the lobes lanceolate, acuminate; axis rudiment absent in 

 the upper flowers, present in the lowest as a slender awn 2 mm. long, pilose 

 below; bractlets 2, lanceolate, acuminate, ciliate above, 3.6 to 4 mm. 

 long; calyx 10 mm. long (including the glabrous 6.5 mm. long stipe-like 

 base), the lowest lobe of the limb short-pointed, ciliate and pilose dor- 

 sally, the others blunt and merely ciliate; flowers, yellow; banner broadly 

 obovate, 7 mm. long, 6 mm. wide; whole fruit 8.5 mm. long, the lower 

 joint fertile, turbinate-obovate, compressed, 3 mm. long, 2.5 mm. wide, 

 rather densely pilose, 1-nerved on the sides and somewhat reticulate, the 

 upper joint oval-oblong, 4 mm. long, 3 mm. wide, evenly but not densely 

 pilosulous, strongly 1-nerved and reticulate laterally, the incurved gla- 

 brate stoutish beak 1.5 mm. long. 



Type in the U. S. National Herbarium, no. 534322, collected at Caria- 

 manga, Ecuador, altitude 2290 meters, November 24, 1910, by C. H. T. 

 Townsend (no. A57). 



This species evidently belongs in the section Styposanthes, but devi- 

 ates somewhat from the typical members of that group in the absence of 

 the axis rudiment or "seta plumosa" in all but the lowest flower of the 

 spike, a feature already noticed by Taubert in his S. sympodialis and in 

 another member of this section. 5. gloiodes is easily distinguished among 

 the species of Styposanthes by its viscosity and the character of its pod. 



Stylosanthes plicata, sp. nov. 



Stems solitary, frutescent below, 2.7 to 4.2 dm. long, with numerous 

 short, erect branches, glabrate below, above densely pilosulous with loose 

 hairs, glandular-dotted, and more sparsely hispidulous with tuberculate- 

 based ascending hairs; leaves of the branchlets crowded, 3-foliolate; sheaths 

 of the stipules pubescent like the stem, 4 to 6 mm. long, the teeth subulate, 

 2 to 4 mm. long; petioles similarly pubescent, 2 to 4 mm. long, the rachis 

 1 mm. long; leaflets subsessile, elliptic, 5 to 8 mm. long, 1.5 to 2 mm. wide, 

 mucronate, rounded at base, usually plicate and somewhat falcate, above 

 sparsely spreading-pubescent, tuberculate-hispidulous-ciliate, beneath 

 rather densely spreading-pilosulous and stipitate-glandular, more sparsely 

 tuberculate-hispidulous, the 3 to 5 pairs of veins prominent beneath ; spikes 

 oblong or ovoid, 8 to 13 mm. long, about 10-flowered, often aggregated 

 in twos or threes at tips of branches or in the axils; primary bracts pubes- 

 cent like the stem and ciliate, unifoliolate, the sheaths 3.5 to 4.5 mm. long, 

 the teeth 2.5 mm. long, the elliptic petiolulate blade about 4 mm. long; 

 secondary bract 1, bifid to below the middle, ciliate, acuminate, 2.2 to 

 2.7 mm. long; axis rudiment slender-subulate, pilose throughout, 1 mm. 

 long in flower, 3.5 mm. in fruit; bractlets 2, lanceolate, acute, ciliate, 

 2.2 mm. long; flower not seen; lower joint of pod fertile, turbinate-ob-
