162 LXXXIV. APOCYNACE (STAPF). | Holarrhena. 
anthers conniving in a cone, more or less coherent by their tips, 
included, free from the stigma, linear, apiculate or mucronate, the 
outer half of each cell decurrent (sometimes minutely) on and adnate 
to the base of the glabrous connective, adnate tips empty; filaments 
short, filiform, with a hairy swelling at their base running out into @ 
slender filamental ridge. Disc 0. Carpels 2, free; style very short, 
filiform ; stigma below the anthers, ellipsoid to fusiform, entire, viscous 
and more or less agglutinated to the hairy swellings at the base of the 
filaments ; ovules numerous, pluriseriate. Mericarps follicular, divart- 
cate, slender, terete, usually curved. Seeds oblong or linear, seml- 
terete, grooved on the flat (ventral) side, with a tuft of reddish hairs at 
the apex ; endosperm scanty ; cotyledons foliaceous, complicate ; radicle 
short.— Deciduous trees or shrubs, glabrous or more or less hairy. Leaves 
opposite or partly subopposite, herbaceous ; secondary nerves rather 
distant ; petioles glandular towards the base; stipules 0, Corymbs 
many-flowered, terminal or pseudo-axillary ; flowers white, fragrant.
