 ulous at maturity, 2.5-3*^"^ long; stipules spathulate, acute, con- 

 spicuously glandular-serrate, caducous, or on vigorous shoots

 glands; calyx-tube broadly obconic, thickly coated like the 

 short slender pedicels with long white hairs, the lobes acuminate, 

 serrate, with elongated teeth tipped with red glands, dark green, 

 slightly puberulous particularly along the lower side of the prom- 

 inent midvein; stamens 10; anthers large, white; styles 3 or 4, 

 surrounded at the base by a broad ring of white tomentum. 

 Fruit in few-fruited drooping puberulous corymbs, globose,

 orange-red, marked by large pale dots, puberulous toward the 

 base, 1.5-2''"' long, 1-2'='" wide; calyx cavity broad and deep,
