22. Mendoncia mutisii Leonard, sp. nov. FIGURE 13 Suffrutex volubilis, caulibus subquadrangularibus, strigosis; lamina foliorum oblonga, apice acuminata, mucronata, basi angustata, sub- membranacea, supra parce pubescens, pilis e basi stellata orientibus instructa, subtus dense adpresso-pubescens, pilis in costa et venis lateralibus pluribus; flores solitarii vel parci; pedicelli adpresso- pubescentes; bracteae ellipticae, apice rotundatae et apiculatae, basi rotundatae, adpresso-pubescentes; corollae lobi emarginati; ovarium glabrum. Stem subquadrangular, fulvous-strigose, the hairs closely appressed, about 0.75 mm. long; leaf blades oblong to oblong-ovate, up to 9 cm. long and 4 cm. wide, short-acuminate at apex and tipped by a mucro about 1 mm. long, narrowed at base, rather thin, sparingly hirtellous above (hairs ascending, slightly less than 0.5 mm. long, arising from star-shaped bases), rather copiously hirtellous beneath, the hairs curved, ascending, about 0.75 mm. long, those on the costa and veins (4 pairs) more numerous and more closely appressed; petioles up to 1 cm. long, densely fulvous, appressed-pilosulous; flowers 1 to several in the axils; pedicels 1.5 cm. long, densely fulvous, appressed- pilosulous; bracts elliptic, 12 to 13 mm. long, 8 to 9 mm. wide, rounded and apiculate at apex, rounded at base, rather copiously hirtellous without, the hairs curved, ascending or appressed, about 0.5 mm. long; pistil glabrous; calyx subentire, glabrous; corolla (immature) 1 cm. long, the lobes oval, 3 mm. long, 3 to 4 mm. wide, emarginate; anthers sagittate, slightly curved, 4 mm. long, 1.5 mm. wide at base, mucro- nate at tip, one basal lobe slightly longer than the other, both puber- ulous at tip; drupe not seen. Type in the U. S. National Herbarium, No. 1562336, collected in Colombia by J. C. Mutis (No. 916). Mendoncia mutisii is probably related to M. albida, but it has much smaller flowers and a more appressed pubescence.
