A small but widely diflused genus of bttoral trees, growing like Mangroves {Rhizopliora) in tidal estuaries of
most warm countries, and as snch famüiar to all travellers.—Aoofe woody, spreading, standing out of the mud
and over-arching in entangled masses, sending up multitudes of Asparagus-like shoots from their underground parts.
Branches, young ones spreading, pubescent. Leaves opposite, evergreen, petiolate, ovate or oblong, quite entire,
blunt, pubescent below, coriaceous, 2-3 inches long. Bhwers in threes, süky, i inch long, collected in tricliotomous
panicles, crowded, each with three ovate süky bracts. Calyx of five rounded lobes. Corolla coriaceous, shortly cam-
pauulate, four-lobed. Stamens four. Ovary two-celled, with two pendulous ovules in each cell. Style short, bifid.—
-Mter fecundation one ovule commences to gei-minate as the seed ripens, and the others become obliterated.’ Cotyledons
conduphcate, two-lobed; radicle tomentose; plumule two-leaved. (Named in honour of Avicenna, the cele-
brated oriental physician.)

Owing to some mistake, this plant has been reputed as yielding a gum in New Zealand, whence the trivial
name reúnifera was given it. It is also a native of Australia, as far south as Bass’s Straits, and of the Tropics of
both worlds.

Herbs or small shrubs, natives of almost all parts of the world except South Africa; but very few species ai*e
