1 S. xuadagascariense, Prain. A shrub or small tree, 15-20 ft. 

 high, everywhere glabrous ; branches slender ; twigs not perulate. 

 Leaves shortly petioled, opposite, tirmly papery to thinly coriaceous, 

 ovate-lanceolate to ovate-oblong, gradually narrowed to an obtuse or 

 subacute or slightly retuse mucronulate apex, base cuneate, decurrent 

 on the petiole, margin entire, 4-5 in. long, 1-2 in. wide ; petiole J in. 

 long or less, -stout, channelled above, eglandular ; stipules orbicular, 

 mucronulate, fimbriately lacinulate, caducous : young foliage very 

 bright red ; lateral nerves very many, up to 20 on each side, very 

 slender, subhorizontal, parallel. Spikes terminal and in the upper axils, 

 1-li in. long, slender, with a peduncle about \ in. long, with many 

 rather dense ses.sile male flowers above and usually 1-2 subsessile basal 

 females, but occasionally the spikes are male only ; bracts in both sexes 

 1-flowered, widely and shortly oblong, denticulate, 2-glandular at the 

 base. Male : Calyx deeply 8-partite ; lobes lanceolate, acute. Stamens 

 3, exserted. Female : Calyx deeply 3-sect ; lobes ovate, acute or obtuse, 

 denticulate. Ovary glabrous, not horned ; styles 8, shortly connate at 

 the base. Capsule thinly crustaceous, J in. across, breaking up into 

 three 2-valved cocci. Seeds globose, brown, faintly blotched. — Stillingia

A very distinct species, the Eastern representative of S. guineense, 0. Kuntze, 

 from which it is readily distinguished by its almost uniformly opposite leaves with 

 more numerous, nmre slender and more parallel secondary nerves, by the al sence 

 of glands from the petiole or the leaf -base, and by the buds being enveloped in the 

 stipules, without special bud-scales. This is very distinct from S. madagascariense.
