Bentham’ considered this species very similar to Schizolobium excelsum 
Vog., but questioned its standing on account of the absence of fruit. The 
characters of the leaves and flowers are quite sufficient, however, to show that 
the Panama tree belongs to a distinct species. Its racemes are shorter, the 
flowers a little smaller, the petals broader, glabrous, and marked with numerous 
dots between the delicate brown veins; the claw is not only pubescent, but 
covered on its upper part with short, stiff, glandular hairs; the filaments are 
covered with the same kind of indument; and the pubescence on the pistil is not 
dark brown (“atro-fusca”) but quite white. In Schizolobium excelsum the 
inflorescences and leaves are much larger, the pinn# are all opposite, and the 
leaflets are larger, much less oblique, and petiolulate. 
Named for Mr. Frederick V. Coville, Curator of the United States National 
Herbarium, whose constant interest in floristic investigations has contributed 
immensely to the success of the botanical survey of Panama. 
Schizolobium kellermanii Pittier, sp. nov. 
A large tree. 
Leaves bipinnate, the main costa thick, angular, about 25 cm. long, glabres- 
cent, the petiolar part 7.5 cm. long; pinng 20, paired and inserted side by side 
on the upper part of the main costa, the rachis 15 to 20 cm. long, slender, with 
a thick base, more or less angular, subcanaliculate and hairy on the upper side, 
elsewhere glabrescent; leaflets 82 to 42, inserted in pairs side by side on the 
upper side of the rachis, short-petiolulate; petiolules terete, 1 to 1.5 mm. long, 
canescent; leaflet blades oblong, rounded at both ends, mucronulate at the 
apex, 2 to 3 cm. long, 7 to 9 mm. broad, glabrous, dark green and subreticulate 
above, paler and appressed-pubescent beneath. Stipules not seen. 
Floral racemes simple, about 35 cm. long or over, the rachis thick, angular, 
glabrescent or sparsely puberulous, the peduncular part terete, about 6 cm. long. 
Bracts and bractlets absent. Pedicels slender, glabrous, about 6.5 mm. long. 
Calyx tube turbinate, oblique, narrow, costulate, dark brown hairy, the 5 lobes 
reflexed, ovate-oblong, subacute, 10 mm. long, 4 mm. broad, sparsely brown- 
hairy without. Petals 5, obovate-oblong or spatulate, attenuate into a narrow 
claw at the base, rounded-obtuse at the apex, more or less oblique, 1.8 cm. long, 
7 to 9 mm. broad, entirely glabrous. Stamens 10, the filaments, about the length 
of the petals, more or less tomentellous-pubescent at the base. Pistil about 2 
cm. long, the ovary sessile, oblong, compressed, arcuate, densely brown-hairy, 
7-ovulate, attenuate into a long, glabrous style. 
Pod (immature) obovate, slightly oblique, long-attenuate and bearing the 
persistent calyx tube at the base, rounded-obtuse at the apex, about 11.5 em. 
long, 3 cm. broad, entirely glabrous, the pedicel 1.2 em. long. 
Type in the U. S. National Herbarium, no. 578657, collected at; San Felipe, 
Department of Retalhuleu, Pacific coast of Guatemala, flowers and young fruits, 
February 4, 1906, by W. A, Kellerman (no, 5566). 
This new type, through which the area of distribution of the genus is ex- 
tended far beyond its previously known limits, is closer systematically to
