Flowers in 1- to few-flowered cymes, the cymes usually silky white-pubescent; sepals lanceolate to ovate to broadly-ovate, 10- 20 mm long, apically acuminate to long-acuminate, appressed pubescent to glabrate; corolla blue or purple, rarely white, 5-7 cm long, the limb 6-8 cm broad.

Note The name I. indica (Burm.) Merrill (Int. Rumph. Herb. Amb. 445. 1917) based on Convolvulus indicus Burm. (Ind. Univ. Herb. Amb. 7. 1755) has priority over the name used here, but does not clearly refer to the same species.
