• The alliance of this species is apparently with Discocalyx viaculata Merr., 
from which it is readily distinguished by its much smaller, fewer-nerved, 
obscurely maculate leaves. The specialized branches bearing the inflores- 
cences are frequently dichotomous, bearing two cylindric, thickened branches 
at their apices.

An erect glabrous shrub about 2 m high, apparently dioecious, 
the branches subolivaceous, about 5 mm in diameter, longitud- 
inally wrinkled when dry, the tips brown. Leaves somewhat 
crowded toward the apices of the branchlets, chartaceous, oblong, 
14 to 18 cm long, 3.5 to 5 cm wide, subolivaceous when dry, 
slightly shining, of the same color on both surfaces, entire, the 
apex shortly acuminate, base slenderly decurrent-acuminate; 
lateral nerves slepder, the primary ones about 20 on each side 
of the midrib, subascending, slightly curved, the reticulations 
not prominent; petioles 1.5 to 3 cm long. Panicles bipinnate, 
axillary, solitary, up to 10 cm long, long peduncled, the branches 
few, the longer primary ones 1.5 to 2.5 cm in length. Staminate 
flowers 5-merous, their pedicels about 1 mm long. Calyx about 
1.5 mm in diameter, obscurely 5-toothed, distinctly glandular- 
puncticulate, the teeth short, obtuse, minutely denticulate or sub- 
crenate. Petals obovate, 1.2 mm long, glandular-puncticulate. 
Anthers 0.7 mm long.

The alliance of this species is manifestly with Discocalyx cybianthoides 
Mez, which it resembles in its general appearance, in leaf characters, and 
in its panicles springing from the axils of normal leaves, differing essen- 
tially in its very much smaller flowers.
