Trochomeria sagittata (Harv.) Cogn.

Tuber subglobose, attaining the size of an apple, covered with a brownish bark. Stems several from the base, prostrate, occasionally climbing, almost invariably unbranched, slender to filiform, striate, glabrous, rarely over 50 cm long. Leaves rather rigidly herbaceous, 4-7 cm long and 1-4 cm wide at the base, only in exceptional cases reaching 13 x 8 cm (with the basal lobes 6-8 cm long), varying from triangular with a subsagittate base to narrowly sagittate with long basal lobes, or occasionally 5-lobed with two longitudinal parallel basal lobes and two perpendicularly sideways spreading lateral lobes; margin entire, finely scabrid-setulose, the lobes acute, scabrid to glabrous or shortly setulose-hairy; petioles slender to filiform, usually glabrous, 1-2 cm long, ebracteate. Tendrils filiform, glabrous or nearly so. Male flowers usually fasciculate, 1-3, rarely more, per axil, occasionally in a few-flowered subumbellate raceme; peduncles nodding, capillary, usually shortly hairy, 1-4 cm long; pedicels of racemose flowers short; receptacle funnel-shaped to narrowly campanulate, 3-5 mm long and 3-4 mm wide at the throat, usually with a few short appressed stiff hairs; sepals ovate-triangular, up to about 0.5 mm long; petals white to cream or greenish-white, somewhat fleshy, triangular-ovate, obtuse to subacute, 4-6 mm long, densely and finely papillose; filaments short, connective broadened and papillose at the apex; rudiment of ovary represented by a depressed gland-like structure at the base of the receptacle. Female flowers solitary; pedicels and perianth as in the male; staminodes 3, short, thick and fleshy, oblong or somewhat obconical; ovary narrowly ovoid or fusiform-oblong, glabrous and smooth, narrowly apiculate; disc none; style shorter than the laterally flattened, sub-bilobed and more or less flabelliform stigma. Fruit on a peduncle up to 4 cm long, ovoid, acute or shortly acuminate, glabrous, faintly marked with a few fine longitudinal ridges, 16-21 mm long and 11-14 mm in diam. Seeds in the fruits examined 3-4, subglobose-ellipsoid, smooth, 5-6 mm long, 4-5 mm wide and nearly 4 mm thick.
