Information
Perennial or rarely annual (fide Milne-Redhead & Taylor 10707); stems several from a woody tuberous rootstock, yellow-brown, ridged, pilose to glabrous. Leaf-blade ovate-cordate, triangular, oblong-triangular or lanceolate, 1–12 cm. long, 1–9.3 cm. wide, ± acuminate or acute at the apex, truncate, sagittate, hastate or with rounded lobes at the base, glabrous save for the margins which are minutely puberulous; petiole 1–4 cm. long. Inflorescences few–many-flowered, rather dense; peduncle 1.5–12(–23) cm. long; pedicels 0.75–1.2 cm. long. Sepals elliptic-oblong or ovate, 4–8 mm. long, obtuse to acutish, glabrous, the outer ones sometimes verruculose. Corolla lilac-pink or almost white, sometimes with a purple or maroon centre, 2–6 cm. long; limb almost salver-shaped; tube narrow. Stamens and style included or very slightly exserted. Capsule globose, glabrous, (4–)6–7 mm. in diameter. Seeds subtrigonous, pale, about 3 mm. diameter, densely tomentose and also with some longer hairs.

Notes
Indian material of this species has a greater tendency to have entire rather than sagittate leaves but entire leaved forms are quite common in Africa e.g. I. homblei De Wild. If varietal names are necessary they are available. For a on the typifica-tion of Convolvulus maximus L.f. see Verdcourt in K.B. 15 : 7 (1961). This species was for long misidentified with I. sagittata Poir. (with a complicated synonymy) but it is quite distinct.
