PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA, 111 
Fruit not known. 
Type in the U. S. National Herbarium, no. 703583, collected on the P&éramo de 
Piedras Blancas, State of Mérida, in the Venezuelan Andes, at an altitude of 
about 3,800 meters, in flower, March 27, 1915, by Dr. A. Jahn (no. 412), 
This species has the largest flowers among the high Andine species of 
Osteomeles. It is otherwise readily distinguished from the other small-leaved 
species by the transparent spot accompanying the teeth and the linear, canali- 
culate bracts. 
CAESALPINIACEAE. 
A NEW COLOMBIAN SPECIES OF BROWNEA. 
Brownea bolivarensis Pittier, sp. nov. 
A shrub or a small tree, up to about 5 meters high, the trunk 10 em. in 
diameter at the base, the branchlets glabrous, with slightly scaly, verruculose 
bark. 
Leaves mostly 3-jugate; rachis 7 to 16 cm. long, terete, narrowly canaliculate, 
lenticellate or verruculous, the petiolar part 1 cm. long or less. Leaflets 
opposite, glabrous, glandular at the base; petiolules blackish, stout, rugose- 
plicate, glabrous, 3 to 4 mm, long; blades elliptic or elliptic-oblong, attenuate 
and rounded or subcordate at the base, acutely long-acuminate at the apex, 
subinequilateral with the broader half on the lower (outer) side, the basal 
3 to 15 cm. long, 1.5 to 4 em. broad, the terminal 18 to 25 cm. long, 5 to 7 cm, 
broad; upper face of leaflets smooth, pale green, with prominulous costa and 
veins; lower face finely reticulate, the costa and veins prominent, the latter 
doubly anastomosed along the margin; glands basal on either side of the costa. 
Stipules caducous, not seen, 
Spikes pendulous, 7 to 15-flowered, up to 15 cm. long, growing from older 
branchlets. Rachis ferruginous-pubescent. Bracts caducous, not seen. Pedicels 
ferruginous-pubescent, 1 cm. long. Sheath tubular-campanulate, 2.2 em. long, 
minutely ferruginous-pubescent, the lobes rounded and subacute at the apex. 
Receptacle tube about 1 cm. long, widening from base to apex. Sepals 4, oblong 
or obovate, attenuate at the base, subobtuse at the apex, minutely pubescent 
without, the anterior one 3 cm. long, 1.1 to 1.2 cm. broad, the others 3.3 cm. 
long, 0.8 cm. broad. Petals obovate-spatulate, attenuate at the base into a 
slender claw about 1 cm. long, rounded at the apex, 4.7 cm. long, 1.5 em. broad, 
pinkish red, glabrous. Stamens 11, 4 to 4.5 em. long, glabrous, the filaments 
connate into a tube 3.5 em. long; anthers oblong, 5 mm. long. 1.5 mm. broad, 
hairy inside at the apex. Pistil about 6.2 em. long (stipe 0.8 cm., ovary 1.7 
cm., style 3.7 cm.) ; stipe and ovary ferruginous-pubescent ; style glabrous. 
Legume 15 to 25 cm. long, 4.5 em. broad, 4 to 6-seeded, expelling the seeds 
by the curling of the valves. Seeds oblong or obovate, more or less angular, 
laterally compressed, 2.2 to 2.7 cm. long, 1 to 1.5 cm. broad, about 0.8 em. 
thick. 
Type in the U. 8. National Herbarium, no. 920170, collected on the trail 
between Noros{ and Tiquisio, Department of Bolivar, Colombia, at an altitude 
of 150 to 600 meters, in flower and fruit, April-May, 1916, by H. M. Curran 
(no, 142), 
This species is intermediate between Brownea macrophylla Linden and 
B. latifolia Jacq. With the first it has in common the inflorescence growing 
from the old wood, but it differs from it in most of the other characters. It 
has the 3-jugate leaves of the second, but with proportionally much narrower, 
differently shaped leaflets and much larger flowers.
