FIGURE 12 Suffrutex volubilis, caulibus subquadrangularibus vel teretibus, striatis, parce adpresso-hirtellis vel glabratis; lamina foliorum ovata vel ovato-elliptica, acuminata, mucronata, basi acuta vel obtusa, parce adpresso-hirtella vel glabrata, pilis supra e basi stellata orientibus in- structa; flores axillares, fragrantes; pedicelli adpresso-hirtelli; brac- teae ovatae vel oblongo-ovatae, obtusae, minute apiculatae, extus parce adpresso-hirtellae, intus glabrae; corolla subflava, lobis suborbicular- ibus; drupa ovoidea, leviter compressa, glabra. A suffrutescent vine up to 5 meters high; branches subquadrangular to terete, striate, sparingly appressed-hirtellous to glabrate; leaf blades ovate to oblong-elliptic, up to 11 cm. long and 5 cm. wide, grad- ually to abruptly acuminate (the tip blunt and ending in a mucro about 2 mm. long), acute or obtuse at base, thin, sparingly appressed- hirtellous or glabrate, the hairs of the upper surface produced from star-shaped bases, the costa and veins (3 or 4 pairs) inconspicuous; petioles up to 2 cm. long, glabrous or sparingly hirtellous; flowers 1 to several in each axil; pedicels up to 1.5 cm. long, appressed-hirtel- lous; bracts ovate to oblong-ovate, up to 2 cm. long and 1 cm. wide, ob- tuse and minutely apiculate at apex, rounded at base, sparingly ap- pressed-hirtellous without, the hairs 0.5 mm. long or less, glabrous within; corolla cream with brownish markings, glabrous, fragrant, up to 3 cm. long, 6 mm. broad at base, narrowed 5 mm. above base to 3 or 4 mm., thence enlarged to 8 mm. at throat, 2-lipped, the lobes suborbicular, about 5 mm. in diameter; calyx glabrous, subentire; ovary and style glabrous; drupe ovoid, slightly compressed, 1.5 cm. long, barely 1 cm. broad, about 4 mm, thick, glabrous. Type in the U. S. National Herbarium, No. 1706847, collected in second growth along the Río Negrito, 70 km. east of Villavicencio, In- tendencia of Meta, Colombia, December 25, 1938, by Oscar Haught (No. 2494). Other collections are: Caparrapi, in Cundinamarca, altitude 1,260 meters, García-Barriga 7720 (US); in the high forests of Mount Chapón, 3,000 feet, Bayacá, Lawrance 363 (Mo, NY). Mendoncia odorata resembles M. gracilis in many respects but can be separated by its sparingly pilose stems. In M. gracilis the stem hairs are more numerous and usually closely appressed. The veins and vein- lets of the leaf blades of M. gracilis are often much more prominent than those of M. odorata. The name odorata alludes to the fragrant flowers (Haught 2494).
