A tree, varying in height from 10 to 35 meters. and the trunk in diameter 
from 30 to 80 cm. Trunk straight, 7 to 15 meters from base to first branching, 
covered with a grayish, rather smooth bark. Branches ascending, forming a

or less dense, brown or golden brown pubescence. Petioles 5 to 8 mm. long, 
canaliculate, Lamina 7 to 12 cm. long, 3 to 5 cm. broad, ovate, ovate-elliptic,

parallel, arcuately anastomosed near the margin, prominent beneath and slightly 
furrowed above; margin entire, revolute. Stipules 1 to 2 mm. long, hairy, sub- 
triangular or subulate. 
Inflorescence terminal, erect, simple or branching, the floral branchlets 
in the latter case axillary and foliate at the base. Rachis, peduncles, and 
pedicels more or less brownish-tomentose. Individual spikes usually densely 
flowered, 10 to 15 cm, long. Clusters 1 to 5-flowered, borne on a peduncle 2 
to 4.5 mm. long, Pedicels very slender, 4 to 5 mm. long. Bracts very small 
(15 to 2 mm. long), lanceolate-subulate, hairy, caducous. Calyx reddish 
orange, the interior sepal cucullate, 7.5 mm. long, sparsely pubescent at the 
base, 3 mm. broad, with a strongly arcuate spur 8 to 9 mm. long, the 4 posterior 
sepals orbicular and subacute, sparsely ciliate, about 1.5 mm. long and broad, 
but the two middle ones a little larger. Petals light yellow, oblong-spatulate, 
more or less tomentose outside at the tip and along the middle part, the middle 
one about 9.5 mm. long and 3.5 mm. broad, cucullate, the lateral ones spread- 
ing, rounded at the tip, 9 to 9.5 mm. long, 2.5 mm. broad. Staminodes small, 
ligulate, about 1 mm. long. Stamen about 7 mm. long; filament slender, 
sparsely hairy, about 1. mm. long; anther basifixed, naviculiform. Pistil 
glabrous, 6.5 mm. long; ovary trigonous. 
Capsules 2.5 cm. long, dark brown and verruculose outside, hanging from

Seemann identified this species with V. tomentosa DC., from which it seems 
to differ in several well-marked details, such as the smaller stipules, larger 
leaves, more developed inflorescences, etc. The above description agrees more 
closely with that of V. ferruginea Mart., as given by Warming, who likened to 
this Brazilian species the specimens collected at Panama by Hayes. The main 
difference is that the flowers of the Panaman form, as collected by Mr. Chris-
