449 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Type in the U. S. National Herbarium, no. 678894, collected along the rail- 
road near Tabernilla, Canal Zone, Panama, altitude 20 to 25 meters, July 6, 
1911, by H. Pittier (no. 3822). 
Easily distinguished from all other species by the densely pubescent leaves 
and hirtellous corolla. 
5. Watsonamra donnell-smithii Standley, sp. nov. 
Young branches stout, glabrate or sparingly strigillose; ctipules about 5 em. 
long and 2.5 cm. broad, ovate, acuminate or attenuate, densely and finely silky- 
strigillose on the outer surface, glabrous on the inner surface; petioles 9 to 11 
cm. long, minutely strigillose, naked; leaf blade (a single one seen) entire, oval, 
45 cm. long, 28 cm. wide, obtuse at the base, glabrous above, glabrous beneath 
except along the finely silky-strigose veins, these conspicuous, 14 on each side; 
cymes rather densely many-flowered, on stout peduncles 10 to 13 mm. long; 
bracts not seen, evidently early deciduous, or possibly wanting; pedicels very 
stout, 4 to 6 mm. long; ovary densely appressed-pubescent; calyx 12 to 15 mm. 
long, the tube campanulate, 5 to 7 mm. broad, finely pubescent with appressed 
hairs, glandular within near the base, the lobes about equaling the tube, 
obovate or oval-obovate, rounded at the apex, finely striate, sparingly pubescent 
outside, glabrous within; corolla tube 25 mm. long, 3.5 mm. in diameter, 
densely pubescent outside with short appressed hairs, except near the base, 
there glabrous, nearly glabrous within; corolla lobes 6 or 7 mm. long, oblong, 
about twice as long as broad, pubescent outside like the tube, but more densely 
so, glabrate within; stamens inserted 6 mm. above the base of the corolla tube, 
the slender filaments unequal, 11 mm. long or less, villous near the base; fruit 
not seen. 
Type in the U. 8S. National Herbarium, no. 355176, collected near La Emilia, 
Llanuras de Santa Clara, Costa Rica, altitude 250 meters, April, 1896, by John 
Donnell Smith (no. 6590). 
This was distributed as Pentagonia wendlandi, but is very unlike that plant. 
It is most closely related to Watsonamra macrophylla, but that species has per- 
sistent bracts, broader corolla lobes, and a very different calyx. The peduncles, 
pedicels, and bases of the petioles in the type are very densely beset with 
brownish, gland-like tubercles. A few similar tubercles are found on some of 
the specimens of closely related species.

TYPE LOCALITY: Banks of the River Cupica, State of Cauca, Colombia. Type 
collected by Seemann, 
A small tree, about 3 meters high; larger leaves nearly a meter long and half 
as wide. This differs from all other species in the narrowly tubular corolla 
which extends only slightly beyond the calyx and in the peculiar interior appen-
