986 “CXXII, EUPHORBIACEE (PRAIN). | Tragia, 
Baker with this species, serves as a link connecting the two, because the petioles are 
pubescent though the blades of the leaves are not. The species was originally 
tentatively identified by Bentham with 7. cordifolia, Vahl, to which ‘species it is 
indeed closely allied, but from which it is readily distinguished by the smaller 
number and the different shape of tbe lateral lobules of its female calyx-lobes. 
22. T. Okanyua, Pax in Bull. Herb. Boiss. vi. 735. Stems long, 
slender, twining, sparingly branched, less often suberect below and 
rather freely branching from a woody base, twining only above, 
pubescent and copiously armed with stinging hairs. Leaves long- 
petioled, membranous, ovate-triangular or ovate-lanceolate, acute or 
acuminate, base cordate from faintly lobed to distinctly. subhastate, 
margin finely to coarsely crenate-dentate, 14-24 in. long, 3-1} in. wide 
above the basal lobes, 2-2} in. wide at the base, puberulous or 
pubescent and bristly-setose, especially on the nerves, on both surfaces ; 
petiole 4-1} in. long, pubescent and bristly setose; stipules ovate- 
lanceolate, reflexed, 14 lin. long, almost glabrous above, pubescent 
beneath. Racemes lateral, 3-14 in. long, on rather stiff naked bristly- 
setose peduncles 3-1} in. long, with numerous rather lax male flowers 
above and usually 2 basal female flowers ; pedicels all solitary to and 
equalling or slightly exceeding their bracts; bracts all thinly mem~- 
branous, male small, ovate, hirsute, female ovate, acute, faintly 3-lobed 
to, distinctly 3-toothed. Male sepals 3, ovate, membranous, glabrous. 
Stamens 3 ; filaments considerably longer than the anthers ; connective 
slightly thickened. Female calyx-segments 6, 2-seriate, oblong-ovate, 
accrescent and coriaceous, 4 lin. long, rhachis narrow-oblong, pinnately 
2-3-lobulate on each side, lobules all spreading, rather densely bristly as 
is the rhachis externally. Ovary moderately hispid ; styles 3, connate 
in a slender column for half their length. Capsule 3-coccous, sparingly 
bristly-hispid especially above the middle and along the centre, } in. 
across: cocci subglobose. Seeds globose, brownish-grey.—7’. angustt-
