Shrubs up to 2 meters high; stems subquadrangular, the angles glabrous; leaf blades oblong-elliptic, up to 16 cm. long and 6 cm. wide, narrowed to a slender often curved apex (the tip blunt), nar- rowed at base and decurrent on the petiole, glabrous, entire or un- dulate, the costa and lateral veins (about 8 pairs) rather inconspicu- ous; inflorescence a panicle of 3 or 4 branches, up to 15 cm. long, the fascicles small, few-flowered, secund, except occasionally the lower- most, longer than the internodes; bracts ovate, up to 8 mm. long and 5 mm. wide, acutish, the veins obscure; bractlets oblong, up to 7 mm. long and 3.5 mm. wide, rounded, both bracts and bractlets gla- brous except the sparingly hirsutulous tips; calyx up to 12 mm. long, oblong or oblanceolate, 3.5 to 4.5 mm. wide, acutish, glabrous without, puncticulate within, the tips sparingly hirsutulous; corolla bright rose, the tube 4 to 4.5 cm. long, about 4 mm. broad at base, narrowed above ovary to 3 mm., thence gradually enlarged, becoming 7 mm. broad at mouth, rather densely and retrorsely hirtellous distally with white hairs slightly less than 0.5 mm. long, glabrous proximally, the lobes about 4 mm. in diameter, rounded, emarginate; stamens exserted 15 to 20 mm. beyond the mouth of the corolla, the filaments densely pilose or subtomentose at and above insertion, the upper portions sparingly pilose, the hairs longer, reaching 2 mm. in length; anthers 5 mm. long, the cells ventrally hirtellous, the basal spurs 1 mm. long; style and stigma glabrous; fruit not seen. Type in the U. S. National Herbarium, No. 1691751, collected in forest along the Río Putumayo, Comisaría of Putumayo, Colombia, September 26 to October 10, 1930, by G. Klug (No. 1653). Isotypes are in the herbaria of the Missouri and New York Botanical Gardens. Cuatrecasas' No. 10919 (US), collected near mouth of the Río Conejo, Putumayo, 300 meters and Triana's specimen (s. n.) (Col), collected at Barbacoas, Nariño, also represent the species. Sanchezia putumayensis is near S. sylvestris Leonard, of Peru, from which it differs chiefly in its relatively narrower leaf blades with narrowed rather than obtuse bases, and by the pilosulous (distally) corollas (practically glabrous in S. sylvestris). The type (Klug 1653) was erroneously cited under S. sylvestris in the original description of that Peruvian species.
