PITTIER—PLANTS FROM COLOMBIA AND CENTRAL AMERICA. 123 
Collected also near Colonia Tovar, State of Aragua, 1856-7, by A. Fendler 
(no. 2318). 
Fendler’s specimen was first determined by Bentham as Drepanocarpus and 
later as Machacrium leiophyllum Benth. It has certainly very little in common 
with the latter, while its habit, the shape of the long, unguiculate petals, and 
the absence of any appearance of a wing in the developed ovaries all point to 
the former genus. 
This shrub is known among the natives under the name of ‘‘ chaperno.” 
TWO NEW SPECIES OF PTEROCARPUS FROM COLOMBIA. 
Pterocarpus floribundus Pittier, sp. nov. FicurE 60. 
A tree, the branchlets glabrous, lenticellate, 
Leaves 3 or 5-foliolate, the rachis slender, flattened above, 5 to 8 cm. Jong. 
glabrous. Leaflets membranous, the petiolules terete, 4 to 6 mm. long, more or 
less puberulous or pubescent, the blades ovate, rounded 
or abruptly acutate at the base, obtusely long-acumi- 
nate at the apex, 9 to 12 cm. long, 4.5 to 7 em. broad, 
glabrous, minutely reticulate, paler beneath and the 
veins prominent. 
Panicle terminal, many-branched, oblong, 20 to 25 
em. long, abundantly flowered, the main rachis gray- 
ish, glabrous, the rachis of the lateral racemes 4toG 
cm. long, densely ferruginous-hairy. Bracts very 
small, obtuse, hairy. Flowers pedicellate, the pedicels 
3 to 4 mm. long, ferruginous-hairy, provided at the — py¢, 60.—Petals of Ptero-

acute. Petals glabrous, yellow; standard suborbicular, 
attenuate and purple at the base, the claw cuneate, about 4.5 mm. long, the 
blade broader than long, about 9 mm. by 14 mm.; wings oblique, broadly 
ovate, the claw slender, about 4.5 mm. long, the blade 1-auriculate at the 
base, broadly rounded at the apex, about 10 mm. long and 7 mm. broad ; 
carinal petals coherent along the lower margin, subfalcate, the claw 3.5 to 4 
mm. long, the blade oblique-oblong, 1-auriculate, obtuse at the apex, about 8 
mm. long, 4 to 4.5 mm. broad. Stamens glabrous, monadelphous, the filaments 
free for about half their length; anthers oblong. Ovary sessile, 4-ovulate, 
ferruginous-tomentose, the style glabrous, about 10 mm. long, 
Immature fruits orbicular, apiculate laterally. 
Type in the U. S, National Herbarium, no. 704056, collected in Santa Marta, 
Colombia, 1898-9, by H. H. Smith (no. 2030). . 
This beautiful species seems to be very closely related to P. rohrit Vahl from 
the same region, differing mainly in the disposition of the inflorescence, the 
shape and reduced number of the leaflets, the small dimensions of the flowers, 
and the 4ovulate ovary. 
Pterocarpus heterophyllus Pittier, sp. nov. Ficure 61. 
A tree, the branchlets pilosulous, sparsely lenticellate. 
Leaves 5 to 9-foliolate, the rachis slender, glabrous or pilosulous, 6 to 12 cm. 
long. Leaflets coriaceous, very variable in size; petiolules more or less villous, 
8 to 4 mm. long; blades ovate, rounded, truncate, or sometimes subemarginate 
at the base, emarginate at the apex, 1.5 to 8 cm. long, 1.5 to 4 cm. broad,
