PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 468 
more so on the lobes; stamen tube broad, included; pistil up to 15 mm. long, 
glabrous, the ovary long-stipitate (the stipe 1 mm. long). 
Legume not known. 
Type in the Gray Herbarium, collected at Culiacin, Sinaloa, Mexico, by T. S. 
Brandegee, August 25, 1904. 
This species is well characterized by its bushy habit, the small leaves witb 
slender petioles provided with stipitate glands, the small inflorescences, and the 
long-stipitate ovary. Its affinities seem to be with P. paniculatum and P. 
oblongum, on account of the paniculate inflorescences and the stipitate ovary. 
It differs from both in the linear stipules, from the former in the pubescence 
and in the stipitate glands, and from the latter in the size of the corolla and in 
the shorter stipe of the ovary. 
12. Pitheccollobium oblongum Benth. Lond. Journ. Bot. 3: 198. 1844. 
A shrub or small tree, the bark of the young branchlets brownish, more or 
less densely white-lenticellate. 
Leaves bipinnate, subcoriaceous, the basal stipules spinescent, glabrous, 
straight, thick or slender, up to 1 cm. long; petioles canaliculate, glabrous or 
pilosulous, the main ones 0.6 to 2.2 cm. long, with a rather small sessile pertuse 
apical gland; pinnae unijugate, the interpetiolar and interfoliolar stipules 
triangular-acute and very small, the secondary petioles 0.6 to 1.5 em, long, with 
minute apical glands; leaflets unijugate, oblong, oblong-ovate, or obovate, ob- 
tuse or sometimes emarginate at the apex, subcuneate at the base, 2.5 to 4.5 
em. long, 1 to 2 cm, broad, glabrous, the venation prominulous on both sides. 
Spikes forming axillary panicles, the rachis appressed-pilosulous, the bracts 
residual, glandular, with a terminal unguiculate appendix; peduncles 1 to 2 cm. 
long, slender, hairy, the spikes very short and almost globose; bractlets 
minute, lanceolate, hairy, deciduous; flowers small, sessile; calyx 2 mm. long, 
grayish-hairy ; corolla 5 to 5.5 mm, long, pubescent, the lobes subacute, 1.5 mm. 
long; stamen tube included; pistil 14 mm. long, the ovary hairy, long-stipitate 
(the stipe 2 mm. long). 
Legume not seen; according to Bentham, flat before dehiscence, the valves 
8.5 mm. broad. 
Type from Panama (Cuming 1155). The present description is based upon 
specimens in the Gray Herbarium, from Santa Marta, Colombia, H. H. Smith 
28a. This species is reported from the Gulf of Fonseca (Sinclair), Nicaragua 
(Oersted), Panama (Cuming, Seemann, Duchassaing), and Trinidad (Crue- 
ger). 
Bentham’s diagnosis and description apply to the Santa Marta specimens, 
except that in these the flowers are slightly larger. 
13. Pithecollobium subglobcsum Pittier, sp. nov. 
A small tree or shrub, the bark of the young branchlets brownish gray. 
Leaves bipinnate, small, submembranous, the basal stipules spinescent, rather 
slender, up to 5 mm. long; petioles slender, canaliculate, more or less pilosulous, 
the main ones 1 to 1.5 em. long, with a small stipitate apical gland; pinnae 
unijugate, the interpetiolar and interfoliolar stipules more or less obsolete ; 
secondary petioles 4 to 5 mm. long, with a minute apical gland; leaflets uni- 
jugate, subsessile, glabrous, obovate, broad and more or less emarginate at the 
apex, rounded at the base on the outer half, 1 to 2 cmi, long, 0.7 to 1.8 em. 
broad, the reticulate venation prominulous on both sides. 
Spikes forming axillary panicles, the rachis minutely puberulous or pubescent, 
the bracts residual, 1 to 2 mm. long, glandular and appendiculate at the apex 
by the residual interpetiolar stipule; peduncles 1 to 1.7 em. long, slender, the
