FIGURE 11 Herba vel suffrutex volubilis, caulibus subteretibus tenuiter pilosis vel ad nodos pilosis, pilis adpressis vel adscendentibus, fulvis; lamina foliorum oblonga-elliptica, subfalcata, apice acuminata, mucronata, basi angustata, tenuis, parce strigosa vel in costa et venis lateralibus dense strigosa; petioli pilosi; flores solitarii; bracteae ovatae vel ellip- ticae, apice rotundatae vel obtusae, mucronatae, basi rotundatae, pilosae, pilis fulvis; corolla gilva, lobis ovatis, emarginatis; pistillum glabrum. Slender herbaceous or suffrutescent vines; stems subterete, moder- ately pilose or densely so at the nodes, the hairs appressed or ascending, 1 to 2 mm. long, fulvous; leaf blades oblong-elliptic, slenderly acumin- ate, the tip subfalcate and tipped by a slender mucro about 3 mm. long, narrowed at base, thin, rather sparingly strigose, the hairs more nu- merous and more fulvous on costa and lateral veins (3 or 4 pairs), these inconspicuous; petioles 2 to 3 cm. long, sparingly pilose, the hairs ascending; flowers solitary; pedicels 2 to 3 cm. long, pilose, the hairs ascending, about 1 mm. long, light fulvous; bracts ovate to elliptic, 2 cm. long, 14 mm. wide, rounded or obtuse and mucronulate at apex, rounded at base, moderately pilose, the hairs appressed to ascending, 1 to 1.5 mm. long, light fulvous; corolla 3 em. long, cream color, glab- rous, 3 cm. long, the tube about 4 mm. broad at base, slightly con- stricted above ovary, thence enlarged to about 8 mm. at throat, the lobes ovate, about 5 mm. long, emarginate; ovary, style, and calyx (entire) glabrous; fruit not seen. Type in the U. S. National Herbarium, No. 1662515, collected in the San Juan Valley near Puerto Berrío, between Río Carare and Río Magdalena, Department of Santander, Colombia, altitude 100 to 700 meters, June 19, 1935, by Oscar Haught (No. 1799). Mendoncia gilva is closely related to M. odorata. When compared with this species it can be easily recognized by its solitary flowers and by the much longer and less appressed hairs of the more densely pilose bracts. The name gilva alludes to the cream-colored flowers.
