A shrub 1-2 m. high, with numerous small stems, and stout slightly

 bractlets; calyx-tube broadly obconic, coated with matted white 

 haire, the lobes gradually narrowed from wide bases, long, acuminate, 

 glandular-serrate above the middle, villose on the outer surface, 

 glabrous on the inner surface, reflexed after anthesis; stamens 10; 

 anthers cream color; styles 3 or 4. Fruit ripening in October, on 

 elongated slender nearly glabrous pedicels, in few-fruited erect clus-
