PITTIER—REVISION OF THE GENUS INGA. 213 
This species, which is undoubtedly distinct from any other, corresponds fairly 
in its description with Inga eriocarpa Benth., which Bentham united later with 
I. xalapensis. The flowers, however, are larger than in the latter species and 
the pubescence of the calyx is quite distinct. 
Inga fissicalyx Pittier, sp. nov. 
Branchlets subangulate, the bark brownish and lenticellate, the younger 
parts, rachis of the leaves, and inflorescence more or less densely covered with 
a brown, hirtellous pubescence. 
Rachis of the leaves narrowly winged, 11 to 14 cm. long, the petiolar part 
more or less distinctly winged, 1 to 2 cm. long, the wings 3 to 7 mm. broad, the 
terminal ones oblong, the others elliptic; stipules linear-lanceolate, pubescent, 
8 to 10 mm. long, caducous; leaflets 6-jugate, petiolulate, coriaceous; glands 
small, sessile, convex, orbicular or transversely ovate; petiolules thick, 2 to 3 
mm, long, densely brown-hairy; leaflet blades lanceolate or oblanceolate, nar- 
row and rounded at the base, long-attenuate and acute at the apex, sparsely 
covered above with appressed hairs except on the densely pubescent costa, softly 
hairy ard reticulate beneath, the costa and veins densely pubescent and promi- 
nent, the blades of the basal pair 2.5 to 3 cm. long, 1.5 cm. broad, those of the 
terminal pair 8 to 11 cm. long and 2.5 to 3.5 em. broad. 
Inflorescences axillary and geminate; peduncles striate, 5 to 7 cm. long; 
flower heads elongating in anthesis, the rachis 5 to 8 cm. long; flowers sessile, 
caducous; bractlets lanceolate, subobtuse, light brown pubescent, about 10 mm. 
long, caducous; calyx tubular, narrow at the base, gradually widening toward 
the apex, densely fuliginous-pubescent, 20 to 28 (23) mm. long, the teeth nar- 
row and pointed, 8.5 to 12 mm. long; corolla tubular, narrow, gradually widen- 
ing toward the apex, softly villous, 18 to 23 (21.5) mm. long, the.lobes wide and 
obtuse, 3 to 4 mm. long, reflexed ; staminal tube equaling the corolla, the stamens 
5 to 6 cm. long; pistil about 8.5 cm. long, the ovary linear, sessile, 3 to 4 mm. 
long, bisulcate, glabrous, 20 to 22-ovulate; style filiform, attenuate, capitellate, 
Legume not known. 
Type in the Gray Herbarium, collected in the vicinity of Zacuapan, State of 
Veracruz, Mexico, flowers, May, 1906, by C. A. Purpus, (no. 1917). 
Also collected in eastern Guatemala, without further data, Bingham (Gray 
Herb.). 
This species has been distributed as Inga ralapensis Benth.? According to 
the incomplete diagnosis, however, the latter species has 5-jugate leaflets, and in 
specimens authentically identified the calyx is only about 11 mm. and the 
corolla about 16 mm. long, while in our species the calyx is 23 mm. long and 
the corolla shorter, even, or slightly longer than the calyx. The very long 
ealyx teeth and the comparatively short corolla lobes are other characteristic 
features of I. fissicalyz. 
Inga holtonii Pittier, sp. nov. 
A tree; young branchlets angulate, densely ferruginous-velvety. 
Rachis of the leaves thick, winged, densely ferruginous-velvety, 14 to 19 cm. 
long, the petiolar part narrowly winged, 3.5 to 4.5 cm. long, the interfoliolar 
wings 1 to 1.5 cm. broad; stipules linear, pubescent, about 1.5 cm. long, caducous ; 
leaflets 4 or 5-jugate, short-petiolulate (the petiolules not over 1 mm. long), 
thick, coriaceous; glands very small, subsessile; leaflet blades oblong or obovate, 
broadly rounded at the base, acute and mucronate at the apex, the upper face 
sparsely appressed-hairy or glabrescent, the costa and veins densely ferruginous- 
hairy, the lower face ferruginous-tomentose, reticulate, the costa and veins very 
prominent and hairy; basal leaflets 7 to 8 cm. long, 3.5 cm, broad, the terminal 
ones 14 to 19 em. long, 5 to 7 cm, broad.
