134 CONTRIBUTIONS FROM: THE NATIONAL HERBARIUM, 
15 to 18 mm. long, acuminate to a subulate tip, narrowed toward the base, sparingly 
pubescent; corolla tube 45 mm. long, scabro-hirtellous; fruit not seen. 
Type in the U. S. National Herbarium, no. 861251, collected in thickets and along 
roadsides near Nicoya, Costa Rica, May, 1900, by A. Tonduz (Inst. Fis. Geogr. Costa 
Rica, no. 13934). The specimens on this sheet bear staminate flowers. The descrip- 
tion of the pistillate flowers is based upon a specimen mounted on sheet 474620, col- 
lected near Las Huacas, Nicoya Peninsula, Costa Rica, altitude 900 meters, May 24, 
1903, by O. F. Cook and C. B. Doyle (no. 724). - 
The only closely related species described from Central America is Basanacantha 
monantha (Benth.) Hook. f., the type locality of which is Guatemala. That has 
thickish, differently shaped leaves, and a very different calyx and corolla. The 
native name of the Costa Rican plant is ‘‘crucilla.”’ 
Basanacantha pitteri Standley, sp. nov. 
Branches stout, spreading, glabrous, grayish brown, with numerous light-colored 
lenticels; stipules distinct, broadly ovate, acutish, thin, brown, glabrous outside, 
densely silky-pilose within with white hairs; petioles stout, 9 to 14 mm. long, densely 
pubescent with stiff stout spreading tawny hairs; leaf blades broadly obovate or oval, 
12 to 46 cm. long, 7 to 10 cm. wide, abruptly acute, with a subulate tip 1 to 2 mm. 
long, rounded at the base, thin, dull green, loosely strigose above, slightly paler 
beneath and densely pubescent with long slender stiff leose hairs; only staminate 
flowers seen, these few together at the ends of the branches; calyx tube campanulate, 
4 mm. long, the lobes subulate, of about the same length, the whole calyx glabrous 
except for a few long slender white hairs on the lobes and about the margin of the 
tube; corolla white, the tube 6 cm. long, slender, slightly dilated in the throat, 
glabrous outside, villous within, the lobes lanceolate or elliptic-lanceolate, 25 to 30 
mm, long, long-attenuate; anthers linear, sessile in the throat of the corolla, 1 cm. 
long; style slender, 45 mm. long, glabrous. 
Type in the U. 8. National Herbarium, no. 578473, collected at Zent Junction, 
near Matina, Costa Rica, February, 1900, by H. Pittier (Inst. Fis. Geogr. Costa Rica, 
no. 16036). 
There is a well developed style present in all of the flowers, but it appears to be 
abortive, and the form of the calyx and the sterile ovary shows very plainly that the 
flowers are not fertile. In general appearance B. pittieri is similar to the preceding 
species, but it differs conspicuously in the nearly glabrous calyx, glabrous corolla, 
larger, broader leaves, and short petioles. 
Basanacantha lasiantha Standley, sp. nov. 
Branches rather slender, glabrous, divaricately branched, each bearing near the end 
2 short stout spines 6 mm. long; stipulesdistinct, 6 to 8mm. long, ovate or ovate-oblong, 
obtuse, glabrous outside, densely pilose within; petioles slender, 6 to 15 mm. long, 
tomentose; leaf blades broadly obovate, thin, 7 to 12 cm. long, 3.5 to 6.5 cm. wide, 
acute, sometimes abruptly so, acute or rounded at the base, abundantly scabro- 
hirtellous on the upper surface, densely pubescent beneath with rather short loose 
soft whitish hairs, not conspicuously veined; only pistillate corollas seen; corella tube 
6 to 7 cm. long, densely pubescent outside with long soft white appressed hairs, villous 
within, the 5 lobes narrowly lanceolate, 45 to 70 mm. long, 9 to 12 mm. wide, long- 
attenuate, more or less sericeous outside, glabrous within; anthers inserted in the 
throat of the corolla tube, linear, sessile, 10 mm. long. 
Type in the U. 8. National Herbarium, no. 678517, collected in forests on dry 
limestone around Alhajuela, Chagres Valley, Province of Panama, Panama, altitude 
30 to 100 meters, May 12 to 15, 1911, by H. Pittier (no. 3473), 
The specimens are incomplete, the flowers being represented only by staminate 
corollas, no calyx being present. This is perhaps nearest Basanacantha monantha, but
