Resource Type Reference Sources
Range Merremia kentrocaulos occurs in Africa south of the Sahara southwards to Botswana and the Northern Province and Mpumalanga. It is also found in India. It grows in bushveld and savanna on sandy or rocky soils from 200-1 300 m altitude. Map 32.
Information Large, glabrous, twining perennial. Stems becoming woody and up to 15 m long, younger ones slender, herbaceous but firm, terete, usual­ly distinctly muriculate with reddish papillae (as are petioles, peduncles and pedicels). Leaves pentagonal in outline, 40-150 mm long and wide, palmately dissected nearly to base; base cordate with a narrow sinus; lobes 5-7, oblong to lanceolate in outline, obtuse to subacute, entire to irregularly and jaggedly pinnatilobed or pinnatifid; petiole 20-60 mm long. Inflores­cence cymose, 1- to few-flowered. Peduncles patent to suberect, 30-90 mm long; bracteoles ovate, acute, concave, 3-5 mm long, early deciduous, occasionally larger and dissected like leaves; pedicels up to 30 mm long, at first deflexed, patent to suberect when flowers open and ultimately cernuous in fruit. Sepals ovate-oblong or elliptic, coriaceous with thinner sub-membranous edges, glabrous, concave, some­what unequal, obtuse or rounded and minutely mucronate, up to 30 mm long (inner ones longer than outer ones) and ± 12 mm wide. Corolla funnel-shaped, white to dull pale yellow or buff with dark purple centre, glabrous, 40-60 mm long, 60-80 mm wide; limb faintly 5-angled, plicate: midpetaline areas not sharply defined. Capsule narrowly ellipsoid, 12-15 mm wide, pale brown, dehiscing by 4 valves and circum-scissile at base, at first enclosed in accrescent, brown calyx, but ultimately exposed just before dehiscence when sepals spread out. Seeds brown to black, minutely hairy, 8-9 mm long, ± 6 mm broad. Flowering time July to April, mostly in February and March.

Stems becoming woody, the younger ones slender, herbaceous, terete, usually distinctly muricate with reddish papillae (as are the petioles, the peduncles and the pedicels). Leaf lamina, pentagonal in outline, 4–13 cm., as long and as wide, palmately dissected nearly to the base (base cordate with a narrow-sinus); lobes 5–7, elliptic, lanceolate or oblong-lanceolate, up to 6·5 × 2 cm.; acute, entire or minutely crenulate in var. kentrocaulos or deeply pinnatifid in var. pinnatifida; petiole 3–7 cm. long, often muriculate. Inflorescence cymose, few-flowered or reduced to a single flower. Peduncle patent to suberect, 3–8 cm. long, often muricate; bracteoles ovate, acute, early deciduous, occasionally larger and dissected like the leaves in var. pinnatifida; pedicels up to 3 cm. long at first deflexed, patent to suberect when the flowers open and ultimately cernuous in fruit. Sepals ovate-oblong, up to 3 cm. long, obtuse edges, glabrous, concave, somewhat unequal, enlarging in fruit. Corolla funnel-shaped, yellow or white dark purple centre, glabrous, 3·5–5·5 cm. long; limb faintly petagonal, plicate, lobes bluntly triangular.
