below the pairs of leaflets; leaflets 3 to 7-jugate, the petiolules about 1 mm. 
long, hairy, the blades broadly ovate or obovate, rounded or subcuneate at the 
base, broadly obtuse and sometimes subemarginate at the apex, dark green, 
shiny, and pilosulous above, paler and sparsely hairy beneath, 1.5 to 4 cm. 
long, 1 to 2.5 cm. broad, the venation prominulous above, less so beneath. 
Inflorescences umbellate-capitate, single or geminate in the upper axils, the 
peduncles 3 to 7 cm. long, brownish-hairy ; flowers long-pedicellate, the pedicels 
about 15 mm. long, slender, hairy; calyx tubular-campanulate, broadly toothed, 
densely brownish-hairy, about 5.5 mm. long; corolla white, densely hairy, 9 to 
9.5 mm. long, the lobes long-triangular, acute, about 3 mm. long; stamen tube 
included, the stamens pink; pistil about 30 mm. long, the ovary short-stipitate, - 
pubescent. ; 
Legume (immature) straight, hairy, short-stipitate, apiculate, about 15 cm. 
long and 1.2 cm. broad. 
Type in the U. S. National Herbarium, no. 860140, collected at El Coyolar, 
near Orotina, Costa Rica, at an altitude of 100 to 200 meters, by Carlos Werckle. 
I refer also to this species a flowering specimen collected in a garden at 
Panama City by Brother Celestine (no. 36), November 5, 1912, from a tree 
which is said to shed its leaves four times a year. 
The species is characterized mainly by its general hairiness and the long- 
pedicellate flowers. 
Pithecollobium macradenium Pittier, sp. nov. 
Section Samanea, series Carnosae. A tree, 15 to 20 meters high, the trunk 
75 em. in diameter, the crown rounded-depressed. 
Rachis of the leaves minutely pubescent, the petioles 3.5 to 7 cm, long; 
pinnae usually trijugate, with a very large cupular coriaceous gland between 
the basal pair; leaflets 5 to 8-jugate, subsessile, with a more or less developed 
pedicellate gland at the insertion of each pair, the blades inequilateral at the 
base, rhombic-ovate or ovate, broadly rounded at the apex, glabrous above 
except for the pubescent costa, paler and more or less pilosulous beneath, 2 to 5 
em. long, 1 to 2.2 cm. broad. 
Inflorescences capitulate, the peduncles 5 to 6 cm. long, ferruginous-pu- | 
bescent ; flowers small, short-pedicellate, white; pedicels 2.5 mm. long, sparsely 
puberulous; calyx campanulate, 383 to 3.5 mm. long, puberulous, the teeth 
short, subacute; corolla 6 to 6.5 mm. long, the tube glabrous, the lobes lanceo- 
late-acute, minutely brownish-pubescent; stamen tube included; pistil about 
15 mm. long, the ovary short-stipitate, glabrous. 
Pod thick, strongly arcuate, compressed, transversely sulcate between the 
seeds, about 10 cm. long, 2 cm. broad, short-stipitate, the peduncle thick, 5 
em. long. 
Type in the U. 8. National Herbarium, no. 716482, collected at Monte Lirio, 
Canal Zone, Panama, May 6, 1912, by E. D. Christopherson (no, 196). 
The most remarkable character of this species is the extraordinary develop- 
ment of the gland at the insertion of the basal pinnae. It is often over 1 cm. 
long, and in its fresh condition forms a deep cup, which is usually visited by 
ants, according to the collector’s notes. The interfoliolar glands, although 
of ordinary size, also are more developed than is generally the case in the genus. 
Pithecollobium chagrense Pittier, sp. nov. 
Section Caulanthon. A low spreading tree. 
Leaves short-petiolate (petioles about 0.5 em. long); pinnae unijugate, the 
rachis pubescent or subglabrous, 5 to 12 em. long; leaflets 3-jugate, more or 
less alternate, coriaceus, the petiolules pubescent, 2 to 3.5 mm, long, the blades 
ovate-elliptic or sometimes ovate, cuneate at the base, acute at the apex, 4.5
