Names
TRAGIA Zenkeri Pax [family EUPHORBIACEAE], in Engl. Jahrb. xxiii. 528. —De Wild. & Durand, Contrib. Fl. Congo, i. 52 and Reliq. Dewevr. ii. 212; Th. & Hél. Durand, Syll. Fl. Congol. 498.
Information
Stems long, slender, twining, armed with stinging hairs. Leaves distinctly to long petioled, membranous, oblong to obovate-oblong, shortly and acutely acuminate, base truncate or very shallow wide-cordate, margin shortly to distinctly and coarsely toothed, 2–3 in. long, 3/4–1 in. wide, rather sparingly beset with long spreading bristly hairs on both surfaces, usually more densely bristly, especially on the nerves beneath, otherwise glabrous, sometimes nearly glabrous beneath; petiole 1/2–2 in. long, densely setose with spreading bristly hairs; stipules lanceolate, erect, 1/5– 1/4 in. long, beset with bristly hairs externally. Racemes lateral, slender, rather dense, 1/4– 1/2 in. long, with a naked, slender, pubescent peduncle 1–1 1/2 in. long, with numerous male flowers above and 1–2 basal female flowers, pedicels in both sexes much shorter than and solitary to the bracts; male bracts obovate or spathulate, obtuse, 1–2 lin. long, finely pubescent; female bracts orbicular-ovate 3-lobed; bracteoles obovate, obtuse. Male sepals 3, ovate. Stamens 3; filaments short. Female calyx-segments 6, ovate-lanceolate, membranous, at length accrescent but hardly coriaceous, 3 lin. long, pubescent, pinnately 3-lobed on each side, rhachis rather narrow, lateral lobes short, terminal laminula large, orbicular-oblong, membranous, nearly or quite as long as the rhachis. Ovary rather densely pubescent; styles 3, pubescent, united for half their length. Capsule 3-coccous, rather sparingly strigose, 1/3 in. across; cocci subglobose. Seeds globose, dark brown with white spots.
