1006 CXXII. EUPHORBIACEH (PRAIN). [Spirostachys. 
ovules in each cell solitary; styles 2-3, shortly connate below, free 
above, entire. Capsule 3-dymous, occasionally 2-dymous, breaking up 
explosively into two or three 2-valved cocci. Seeds wide-ovoid, without: 
a caruncle; albumen fleshy; cotyledons broad, flat.—A tree, every- 
where glabrous ; wood hard, durable, odoriferons. Leaves 2-glandular 
at the apex of the petiole, alternate, crenulate, firm; stipules minute, 
deciduous. Flowers in normally 2-sexual cylindric sessile lateral 
eatkin-like spikes, which precede the leaves; bracts imbricate, 
eglandular, each subtending a solitary flower; males numerous ;. 
females 1-3 at the base of the catkin or occasionally absent; at times 
only 1-sexual male catkins found on an individual tree, usually both 
male and androgynous catkins present, sometimes all the catkins.

A single species, widely spread in Tropical and South-east Africa. 
A very marked genns, readily distinguished by its united filaments. The 
section Glanduligere, recognised by Pax & K. Hoffmann, is, we believe, better left in 
Excecaria. In cur generic key, p. 448, the male calyx-lobes have inadvertently 
been stated to be valvate; they are however, distinctly, if slightly, imbricate as in 
the allied genus Maprounea. 
1. S. africana, Sond. in Linnea, xxiii. 106. A tree from 
20-70 ft. high, all parts glabrous. Leaves short-petioled, firmly 
membranous or subcoriaceous, ovate-oblong, narrowed to a short blunt 
or subemarginate tip, base rounded, margin crenulate, 14-24 in. long, 
$-14 in. wide, somewhat polished above, paler beneath, obscurely 
penninerved ; petiole } in. long, 2-glandular at the top; stipules very 
small. Inflorescences catkin-like, lateral, sessile, appearing before the 
leaves, very dense, cylindric, 1-3 in. long; bracts closely imbricate, 
eglandular, spirally arranged, each subtending a single flower and 
concealing the calyx; flowers many, sessile males above, 1-3 basal 
shortly pedicelled female, their pedicels elongating in fruit. Capsule 
subglobose, 2 in. across ; cocci 2-valved, valves thinly woody, opening 
explosively ; pedicels in fruit } in. long. Seeds wide-ovoid, { in. long-
