A glabrous, apparently dioecious shrub, the ultimate branches 
slender, about 1 mm. in diameter, somewhat angled. Leaves char- 
taceous to subcoriaceous, lanceolate to obloug-lanceolate, 11 to 20 
em. long, 2.3 to 5 em. wide, narrowed upward to the slenderly 
acuminate apex, the acumen frequently falcate and rather abruptly 
narrowed below to the cuneate base, the upper surface olivaceous, 
smooth, the lower surface paler and very minutely verruculose when 
dry; lateral nerves about 5 on each side of the midrib, rather 
sharply ascending, distinct, obscurely anastomosing, the primary 
reticulations slender, rather lax; petioles 2 a 3 mm. long; stipules 
acicular, about 4 mm. long. Flowers axillary, fascicled, “the pistil- 
late ones few, their pedicels up to 6 mm. ine Sepals 6, lanceo- 
late, about 2 mm. long, acute or somewhat acuminate, the alternat- 
ine ones slightly narrower than the others. Ovary globose, gla- 
brous, 3-celled, about 0.8 mm. in diameter. Style cylindric, 2.5 
min. long, about as thick as the ovary, not contracted at the base, 
very shortly 3-lobed at the tip. Staminate flowers apparently 
somewhat abnormal, their pedicels up to 1 em. in length, frequent- 
ly supphed with one or two lanceolate bracteoles, the outer three 
sepals lanceolate, acuminate, about 2.5 mm. long, accrescent and 
attaining a length of 4.5 mm., the inner three lanceolate, not 
exceeding 3 mm. in length. Stamens 3, united, the anthers about 
2 Yam. long, the connectives slightly produced.
