subsessile, membranous; glands small, orbicular, light brown, pertuse, with a 
dark pit, long-stipitate (stipe about 2.5 mm. long, very slender); leaflet 
blades ovate to lanceolate, rounded or cuneate at the base, acuminate with a 
hairy mucro at the apex, sparsely covered with long hairs (mostly inserted on 
the veins and venules) on both sides, ciliate on the margin, the blades of the 
basal pair 3.5 to 5.5 cm. long, 2 to 3 em. broad, those of the terminal pair 9.5 
to 18 em. long, 3.5 to 5 cm. broad. 
Inflorescences axillary, single; peduncles long-hairy, slender, about 8 cm. 
long; flower heads oblong, the rachis about 3 em. long; flowers pedicellate ; 
bractlets lanceolate, 2 to 4 mm. long, hairy outside, glabrous inside, subpersis- 
tent; pedicels hairy, 1.9 to 2.8 (2.3) mm. long; calyx tubular, sparsely hairy, 
4 mm. long, the teeth small, acute, separated by rounded sinuses; corolla tubu- 
lar-funnelform, villous, 10.8 to 11.5 (11.1) mm. long, the lobes short (2.5 mm.

Type in the U. 8. National Herbarium, no. 408211, collected near the Finca 
Sepacuité, Alta Verapaz, Guatemala, in forest, flowers, March 27, 1902, by O. F. 
Cook and R. F. Griggs (no. 505). 
Numbers 202 and 226 of the same collectors are leaves obtained at the same 
date and locality. 
The pedicellate flowers of this species constitute a new departure among the 
Pseudingae-Vulpinae. While its general affinities seem to lean indisputably to 
this group, the plant stands by itself on account of its habit and other char- 
acters, and no closer relationship can be suggested. 
The collectors note that the flowers are almost scentless. 
Series 8. DYSANTHAE. 
A NEW SPECIES. 
Inga standleyana Pittier, sp. nov. 
A low tree with rounded crown, the young branchlets, peduncles, rachis of 
the leaves, and flower heads densely ferruginous-hairy. 
Rachis of the leaves nude, terete, 10 to 15 cm. long, the petiolar part 2.5 to 4 
em. long; stipules absent or very early deciduous; leaflets 4-jugate, or very 
seldom 3-jugate, subsessile; glands large, sessile, pertuse, the rim light brown, 
the pit dark brown; leaflet blades suboblique, ovate or obovate, rounded 
and subemarginate at the base, acuminate or obtuse at the apex, glabrous 
and sublustrous above (except on the ferruginous-hairy costa), the veins slen- 
der and impressed, softly villous and prominently veined and reticulate be- 
neath, ciliate on the margin, the blades of the basal pair 5 to 9 cm. long, 4 to 
4.5 ecm. broad, those of the terminal pair 11 to 18 cm. long, 6.5 to 8 cm. broad. 
Inflorescences axillary, mostly geminate, sometimes single; peduncles 2.5 
to 4 cm. long; flower heads elongate, the rachis 2.5 to 5 em. long; flowers 
thick and short, deciduous; bractlets very small (about 1 mm. long), ovate, 
pubescent without, glabrous within, caducous; calyx 5 mm. long, tomentose 
without, hairy at the base, glabrous at the apex within, the teeth broad, ob- 
tuse, separated by shallow, rounded sinuses; corolla 20 mm. long, broad, 
tomentose outside, glabrous inside, the lobes 3 to 4 mm. long, broad, obtuse; 
staminal tube equaling the corolla, pink, as also the filaments; ovary with a 
single series of minute white hairs along the sutural lines; style about 5 cm. 
long. 
Legume flat and densely rufous-hairy (not seen).
