Calyx 5-partitus, equalis. Corolle tubus mediocris, campanulatus; limbo 4-partito, patente, lacinia 
postica parum dissimili. Stamina 4, subineequalia. Ovarium 2-loculare; loculis 2-spermis, ovulis pendulis. 
Stylus brevis. Stigmata 9, acuta. Pericarpium l-spermum, coriaceum, 2-valve. Semen germinans.

A small but widely diffused genus of littoral trees, growing like Mangroves (Rhizophora) in tidal estuaries of 
most warm countries, and as such familiar to all travellers.—Roots 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. lowers in threes, silky, + inch long, collected in trichotomous 
panicles, crowded, each with three ovate silky bracts. Calyx of five rounded lobes. Corolla coriaceous, shortly cam- 
panulate, four-lobed. Stamens four. Ovary two-celled, with two pendulous ovules in each cell. Style short, bifid.— 
After fecundation one ovule commences to germinate as the seed ripens, and the others become obliterated. Cotyle- 
dons conduplicate, two-lobed; radicle tomentose ; plumule two-leaved. (Named in honour of Avicenna, the cele- 
brated oriental physician.)

Haz. Northern Island. From the Thames river, northward. Chatham Island, Diefenbach. Nat. name, 
* Manawa,” Cunn. 
Owing to some mistake, this plant has been reputed as yielding a gum in New Zealand, whence the trivial 
name resinifera was given it. It is also a native of Australia, as far south as Bass’s Straits, and of the Tropics of 
both worlds.

Shrubs or small trees, belonging to a natural family that is hardly known out of Australia, Tasmania, and the 
Pacific Islands. Leaves without stipules, opposite or alternate, viscid when young, often covered with transparent 
glands. Flowers in axillary bundles or from the branches; pedicels one- -flowered, without bracts. Calyx small, five- 
parted. Corolla hypocrateriform or bell-shaped, bearded within, five- lobed. Stamens five, inserted in the tube of 
the corolla. Ovary two- to four-celled. Ovules four, one in each of the cells, or two when the ovary is two-celled. 
Drupe a berry. (Name from pvo, to shut, and mopos, a pore; from the cavities in the leaves.)
