1-floris, sepalis liberis, acutis vel acuminatis, denticulatis, sta- 
minibus 3; floribus 5 paucis, ad basin inflorescentiae vel in 
racemis brevibus distinctis. 
A glabrous monoecious shrub the branches and branchlets 
terete, brownish. Leaves alternate, linear-lanceolate, subcoria- 
ceous, entire, 6 to 11 cm long, 6 to 10 mm wide, greenish-oliva- 
ceous and shining when dry, subequally narrowed to the acute 
base and to the obtuse to slightly acuminate apex, the margins 
recurved; lateral nerves 15 to 20 on each side of the midrib, 
distant, slender, leaving the midrib at right angles. Racemes 
axillary, 2 to 3 cm long, some all staminate, others with one or 
two pistillate flowers at the base. Staminate flowers numerous, 
one to each bract, their pedicels about 0.5 mm long, the bracts 
broadly ovate, acute to acuminate, about 1 mm long, usually with 
two small, subbasal glands on each side. Sepals 3, ovate, acum- 
inate, about 1 mm long; the margins slightly lacerate-dentic- 
ulate. Stamens 3; filaments free, about 1 mm long. Pistillate 
flowers few, one or two at the base of the staminate raceme or 
on short separate racemes. Sepals 3, oblong-ovate, acuminate, 
margins lacerate-denticulate. Ovary ovoid; style arms stout, 
recurved, 1.5 to 2 mm long. Cocci about 6 mm long, the seeds 
dark-brown, smooth, shining, ovoid-subglobose, 4 to 5 mm long.
