Perennial herbs with woody rootstock. Stems slender, spreading, much branched, up to 1 m long, brownish pubescent. Leaves oblong to ellipticovate, 2–3 × 1.5–2 cm, oblong to emarginate at apex, entire, cordate to truncate at base, densely pubescent on both surfaces, sparsely pubescent at maturity; petioles 1–2 cm long, densely pubescent. Inflorescences cymose; peduncles c. 0.8 cm long, hairy; bracts ovate, 0.5–0.6 × 0.4–0.5 cm, acuminate, hairy out, glabrous in, pink. Flowers sessile or sub-sessile. Sepals 5, unequal, outer 2 ovate, 1.5–1.7 × 0.6–0.7 cm, middle 1 lanceolate, 1.5–1.6 × 0.5–0.6 cm, inner 2 linear, 1.5–1.6 × 0.2–0.4 cm, bristly hairy out, glabrous in. Corolla funnel–shaped, 3–3.5 cm long, pink; tube 2–2.5 cm long, pubescent out, glabrous in; lobes 1.2–1.5 cm

long, pink. Stamens sub-equal; filaments included, 1.7–2 cm long, attached to the base of corolla tube, hairy at base; anthers 2-celled, dehiscing longitudinally; pollen grains globular, pantoporate, echinate. Carpels 2, fused; ovary ovoid, glabrous, c. 0.2 × 0.1 cm; style 2.8–3 cm long; stigma bi-lobed, slightly exserted, pink. Capsules globose, 0.8–1.2 × 0.5–0.9 cm, glabrous, brown. Seeds ovoid, 0.5–0.7 × 0.4–0.5 cm, brown pubescent, hairy at margins.

Flowering & fruiting: January–March.

Habitat: In rocky crevices at elevation of 1380 to 1420 m, mostly associated with Cymbopogon martini (Roxb.) Watson , Crotalaria albida B.Heyne ex Roth var. kangrensis Ansari , Shorea roxburghii Don , Indigofera mysorensis Rottler ex DC and Aristida setacea Retz.

Distribution: East Tropical Africa, Botswana, Ethiopia, Malawi, Mozambique, Zambia, Zimbabwe ( Hilliard, 1983) and now in India.

Specimens examined: INDIA, Karnataka, Chikkaballapur district, Nandi Hills , 13 o 21′32.796″N, 77 o 40′35.22″E, 03.03.2019, Kattee, Shimpale & Dalavi AVK14 ( SUK!) GoogleMaps . Tamil Nadu, Tirunelveli district, Kalkkad (Kalakkad), 16.02.1913, D. Hooper & M. S . Ramaswami 311430 (CAL!).

Notes: The species is rare, c. 50 individuals were located in the Nandi hills. It was also collected previously by Hooper and Ramaswami in 1913 from Kalakkad, Tirunelveli district of Tamil Nadu state but misidentified as Ipomoea barlerioides (Choisy) Benth. ex C.B. Clarke. The population from Nandi Hills shows some variations from the protologue like short peduncle, ovate bracts and tubular funnel–shaped corolla but these variations may be due to the change in the habitat.
