Shrub up to 2 meters high, a little branched, the stems subquad- rangular, the hairs curved, more or less spreading, arranged in 2 rows, conspicuously septate, golden brown; leaf blades oblong-ovate or obovate (some of them slightly panduriform), ca. 20 cm. long, 7 cm. wide, acuminate, narrowed at base, rather thin, entire or undulate, the upper surface subnitid, glabrous or the costa bearing a few small hairs, the cystoliths 0.25 mm. long, inconspicuous, the lower surface glabrous except the costa and lateral veins (9 or 10 pairs), these hiretellous with ascending golden brown septate hairs up to about 0.25 mm. long, the cystoliths about 0.2 mm. long, inconspicuous, sometimes drying blackish in young leaves; petioles up to 5 mm. long, hirtellous; spikes terminal or subterminal, the peduncles up to 3 cm. long, glabrous or sparingly hirtellous, the rachis glabrous, marked by a few parallel cystoliths; bracts oblong-elliptic, 25 mm. long, 10 mm. wide, acute, obtuse at base, thin, glabrous, sparingly ciliate, the veinlets coarsely but rather obscurely reticulate; bractlets oblong-lanceolate, 11.5 mm. long, 3.5 mm. wide, acute, obtuse at base, thin, glabrous, the costa rather prominent, the lateral veins delicately and coarsely reticulate; calyx 12.5 mm. long, deeply segmented, the segments lanceolate, 1.5 mm. wide at middle, acute, rather thin, the costa prominent, the 6 or more pairs of lateral veins obscure; corolla scarlet, up to 6 cm. long, except the glabrous basally enlarged portion, rather densely pilose with spreading or retrorsely curved brownish septate hairs up to 0.5 mm. long, the tube 3 mm. wide at base, enlarged to 4 mm. at 3 mm. above base and contracted to 1.5 mm. at 6 mm. above base, thence gradually enlarged to 6 mm. at mouth, densely and retrorsely pilose at and below the insertion of the stamens within the tube, the lips subequal, the upper lip erect, ovate, 12 mm. long, 10 mm. wide near base, 2 mm. wide near tip, bilobed, the lobes 0.75 mm. long, rounded, the lower lip spreading, 13 mm. long, 3-lobed, the lobes oblong-ovate, 11 mm. long, 4.25 mm. wide, rounded at tip; stamens exserted 15 mm. beyond mouth of corolla tube, the filaments glabrous, the anthers 3.5 mm. long, the cells slightly superposed and somewhat obliquely attached by a connective about 0.5 mm. wide, muticous or minutely apiculate at base; ovary glabrous; style glabrous, rather short; mature capsule not seen. Type in the U. S. National Herbarium, No. 2045441, collected in- subtropical forest 12 km. east of Codazzi in the Espíritu Santo Valley of the Sierra de Perija, Cordillera Oriental, and 13 km. from the Venezuelan border, Department of Magdalena, Colombia, 1,250 meters altitude, February 11, 1945, by Martin L. Grant (No. 10900). Justicia enarthrocoma is closely related to J. leucerythra, differing in the subpanduriform leaf blades, the septate golden brown hairs on stems and young leaf blades, and the much larger scarlet corollas, these with a bilobed upper lip. The specific epithet is from the Greek Evapepos, jointed, and kóun, hair.
