Species 1, endemic. 
1. Z. capillipes, Pax in Engl. Jahrb. xlv. 235. A shrub ; branch- 
lets slightly and obtusely angular, sparingly lenticellate, glabrous. 
Leaves oblong or oblong-elliptic, triangular-acuminate, sharply mucro- 
nate, obtuse or subacute at the base, 5-7 in. long, 2-2} in. broad, 
entire, membranous, glabrous; lateral nerves 9-10 on each side, 
spreading and arcuate, looped near the margin, prominent on both 
surfaces ; veins very lax, distinct below ; petiole 3-5 lin. long, closely 
grooved above, glabrous ; stipules foliaceous, broadly reniform, oblique, 
subcordate at the base, encircling the branchlets, mucronate or shortly 
acuminate, about 3 lin. long and 4 in. broad, nervose, glabrous. Flowers 
monecious, axillary, few. Male flowers: pedicel about 2 lin. long, 
glabrous. Sepals 5, rounded-elliptic, rounded at the apex, 1 lin. long, 
membranous, glabrous. Disk flat, adnate to the base of the sepals, 
very slightly 5-lobed ; lobes rounded, alternate with the sepals, slightly 
verrucose. Stamens 5; filaments free to the base, about 1 lin. long, 
glabrous ; anthers large, oblong-ellipsoid, 3 lin. long, glabrous. Rudi- 
mentary ovary very small, slightly trilobed, glabrous. Female flowers 
about 3 in. in diam. when flattened and spread out; pedicel attaining 
1} in. in length, slender, glabrous. Sepals ovate, obtuse, 2$ lin. long, 
1? lin. broad, submembranous, nervose from the base, glabrous. Disk 
as in the male. Ovary ovoid-globose, smooth; styles 3, ascending,

Flowers diecious. Petals and disk absent. Male flowers: Calyx 
composed of 2-5 bract-like free spirally arranged sepals. Stamens very 
many, spirally arranged on a prolonged axis; lowest filaments very 
short and recurved, remaining anthers sessile ; anthers elongated, more 
or less applied to the axis; cells distinct, adnate to the connective, 
dehiscing longitudinally. Rudimentary ovary absent. Female flowers : 
Calyx 5-partite ; segments ovate, acuminate, imbricate. Ovary 3-celled, 
densely pilose; styles connate into a pilose column ; stigmas 3, spread: 
ing; ovules 2 in each cell. Capsule breaking up into three 2-valved 
cocci; endocarp crustaceous. Seeds compressed, ovate ; albumen 
fleshy ; cotyledons flat, much broader than the radicle.—A tall erect 
tree; branchlets more or less silky-hairy, angular and articulated. 
Leaves opposite, decussate, long-petiolate, coriaceous, more or less silky 
beneath ; stipules large, coriaceous, connate, interpetiolar and intra- 
petiolar forming a sheath enclosing the flowers and young leaves.
