1-floris, sepalis liberis, acutis vel acuminatis, denticulatis, sta- 

 minibus 3; floribus 9 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.

A most characteristic species easily distinguished from all described 

 forms by its very narrow, elongated leaves.
