Shrubs 1 to 2 meters high, up to 5 cm. in diameter at base, the branches upwardly strigose; leaf blades obovate, up to 25 cm. long and 12 cm. wide, abruptly acuminate at tip, narrowed at base to a short petiole 5 mm. long, shallowly sinuate-dentate or entire, glabrous above or sparingly strigose, the lower surface densely strigose, the hairs about 1 mm. long, the costa and the lateral veins (6 to 12 pairs) rather prominent, more so than above; flowers borne in a subsessile termiwide, glabrous, thin, veiny, each ending in a minute spine; calyx pale green, conical, the segments lanceolate, the posterior one about 15 mm. long and 3.5 mm. wide, the anterior pair slightly shorter and more narrowed, the lateral pair 13 mm. long and 3.5 mm. wide, all acute or acuminate and substriate; corolla pubescent without, about 3 cm. long, very fragrant, creamish, the throat yellow, the lobes ovate to sub- orbicular, about 8 mm. long; ovary glabrous; capsule not seen. Type in the herbarium of the Riksmuseet, Stockholm, collected in a deep forest at El Humbo, Department of Boyacá, Columbia, "3,000 ft." altitude, November 7, 1932, by A. E. Lawrance (No. 565). Type fragments in the U. S. National Herbarium. Isotypes in the herbaria of the Missouri and the New York Botanical Gardens. Aphelandra boyacensis has the general appearance of A. prismatica Nees of Brazil but can be separated by its larger and relatively wider leaf blades, these densely strigose beneath instead of practically gla- brous, and by its shorter and broader spike. The corollas of A. pris- matica have a more slender tube than do those of this new species and are yellow instead of cream and yellow. Named for the Department from whence the type was procured. Only a fragmentary corolla could be found for examination on the type specimen, this consisting practically of lobes only.
