Quamoclit phoenicea (Roxb.) Choisy
Annual climbers, glabrous to sparsely pubescent. Leaves ovate to suborbicular, 2-15 cm long, entire, dentate, trilobate or with 5-7 lobes, basally cordate, acute to acuminate apically, mostly glabrous. Flowers in few-to several-flowered cymes or solitary. Sepals oblong to elliptic, 1.5-3 mm long, apically obtuse to tru ncate, the outer with a 1.6-6 mm long subterminal fleshy arista, glabrous. Corolla red to red-yellow, 2.5-4.5 cm long, salverform. Fruit capsular, subglobose, 6-8 mm long. Seeds dark brown or black, pyriform.
Fl. Per.: November to September, perhaps all the year in some areas.
Type: West Indies. Based on Plumier, Pl. Amer. 81, t. 93.f.2.1756 (lecto.by O’Donell in Lilloa 29: 48.1959).
Distribution: An American species, now cultivated or naturalized in many countries of the Old World tropics.
This is the tropical counterpart of the temperate Ipomoea coccinea Linn. I have assumed that this is the species in Pakistan because the true Ipomoea coccinea Linn. is rarely found in Asia and Ipomoea hederifolia Linn. is reasonably frequent.
