By Henry Pirtier. 
INTRODUCTION. 
The present paper, relating mainly to economically important trees 
of the families Euphorbiaceae and Sapotaceae, is in continuation of 
several others which have appeared in the Contributions from the 
United States National Herbarium ! and is similar in scope. 
MORACEAE. 
A NEW SPECIES OF BROSIMUM FROM COSTA RICA. 
Brosimum terrabanum Pittier, sp. nov. Fiaure 76. 
A large, lactiferous forest tree. Bark smooth, grayish. Crown elongate. 
Leavesrather large, chartaceous, glabrous, petiolate. Petiolesrather thick, shallow- 
canaliculate, 8 to 12 mm. long. Leaf blades elliptic, slightly rounded at the base, 
long and acutely acuminate, 10 to 18 cm. long, 4 to 7 cm. broad. Costa prominent 
beneath; primary nerves parallel, forming with the costa a very open angle (about 
80°). Margin entire. 
Stipules narrowly lanceolate, acute, about 1 cm. long, smooth, caducous. 
Receptacles axillary, globose, about 9 mm. in diameter, pedunculate. Peduncles 
10 to 14 mm. long, slender, smooth. Bracts of the recep- 
tacle surface orbiculate, peltate, pedicellate, hairy-ciliate, 
not over 0.6 mm. in diameter; pedicels hairy, 0.8 to 1 mm. 
long. Bractlets at the base of the stamens broad and very 
short (about 0.7 mm.), hairy and ciliate. 
Stamen 1 to 2.5 mm. long; filament sparsely pubescent; 
anther l-celled, peltate. Style about 5 mm. long, bifurcate Fie. 76.—Flowers of Brosi-

Type in the U. S. National Herbarium, no. 577522, col- 
lected in forests of Pefias Blancas del General, Diquis Valley, Costa Rica, at about 
600 meters above sea level, February 9, 1898, flowers, by H. Pittier (Inst. Fis. Geogr. 
Costa Rica, no. 12029). 
The type specimen includes a few detached receptacles, gathered on the ground, and 
two or three branchlets which may have been culled from the baseof the trunk. A few 
notes taken at the same time give some supplemental information. These materials 
are certainly not a very satisfactory foundation for a new species, but the leaves differ 
greatly from those of Brosimum costaricanum Liebm. in having longer petioles, a large 
blade, and primary nerves almost perpendicular to the costa, and in being thin and
