Ipomoea ochracea G.Don

Stems twining, thin, slender, glabrous or sparsely, shortly and patently pilose; old stems with yellow, lacerate bark. Leaves ovate to broadly ovate, 3.5-8 by 2.5-1 cm, cordate at the base, with rounded lobes, shortly to long-acuminate at the apex, with acute or obtusish mucronulate acumen; mostly glabrous on both sides, the margins sometimes shortly fimbriate; petiole thin, 1-4 cm. Inflorescences axillary, peduncles thin, ½-5(-6½) cm, glabrous or with very short patent hairs, cymosely one-to several-flowered. Pedicels much longer than the calyx, l.5—3(-4½) cm, smooth, glabrous, or hairy like the peduncle, thickened towards the apex in fruit. Bracts minute, oblong to triangular. Sepals equal in length or the outer ones a little shorter, 5-6.5 mm long, oblong to ovate-oblong, with acutish, obtusish, rounded or truncate and slightly emarginate, mucronulate apex, glabrous; outer sepals with thick centre and thin, pale margins, inner ones thinner. Corolla widely funnel-shaped, c. 4-5.5 cm long, yellow (orange-yellow, sulphur-yellow or cream-coloured), with a purple centre (always?), glabrous, the pubescent apical parts of the midpetaline bands excepted. Stamens and style included; filaments unequal in length, hairy at the base. Ovary glabrous. Capsules on reflexed pedicels, broadly ovoid, crowned by the style-base, 10-11 mm high, straw-coloured, 2-celled, 4-valved, at the base with the reflexed sepals. Seeds 4, black, shortly pubescent or farinose, c. 4-6 mm long.

In Timor on rocks near the sea; according to Mrs Walsh restricted to that habitat; in Borneo the species was collected in a fairly open situation on the bank of a small stream, at 20 feet altitude.
