about 1.5 cm long, 5 to 6 mm wide, narrowly obovate, pubescent 
only on the margins in the lower one-third, the upper one-half 
split into 4 or 5 primary, rather narrow divisions, these in turn 
trifid or dichotomously divided into 3 or 4 slender laciniae, the 
base gradually narrowed, acute or obtuse. Stamens about 30; 
filaments short; anthers linear, scabrid, about 4 mm long, one 
cell obtuse, the other a little longer (less than 1 mm), and tipped 
with several short, stiff, white hairs, not apiculate. Ovary ovoid, 
pubescent, 5-celled; ovules several in each cell; style about 1.5 
cm long somewhat pubescent below. Fruit blue, ovoid, smooth 
when dry, subacute or somewhat apiculate, about 1.5 cm long, 
the pulp scanty, the endocarp thick, 1-celled, 1-seeded.

This is undoubtedly the species that Mr. Safford discusses (page 401), 
under the native name yoga. It is apparently a very distinct and charac- 
teristic form, but I do not know any species of the section to which it is 
especially closely allied. The numerous, comparatively small, obtuse, prom- 
inently glandular leaves, and the rather large flowers with nearly glabrous 
petals are characteristic features.

A shrub or small tree, the branchlets, inflorescences, and the 
leaves on the midrib and nerves of the lower surface appressed- 
hirsute, not at all stellate-pubescent, although the stiff hairs are 
sometimes somewhat fascicled. Branches terete, slender, red- 
dish-brown or brownish. Leaves alternate, ovate to elliptic- 
ovate, chartaceous, 10 to 15 cm long, 4.5 to 8 cm wide, the apex 
sharply acuminate, the base slightly but distinctly inequilateral, 
somewhat narrowed and abruptly rounded, rarely slightly cor- 
date, the margins crenate-serrate, the upper surface quite 
glabrous, shining, the lower a little paler, shining, very sparingly 
appressed-hirsute on the midrib and lateral nerves, the lower 
axils prominently bearded; petioles 1.5 to 2 cm long, slightly 
appressed-hirsute. Inflorescence axillary, solitary or two or
