Inflorescence solitary, axillary or in short fascicled racemes. Perianth zygomorphic or actinomorphic, coloured, tubular, tube inflated below, hairy inside, limb oblique, (1-)2 (-3)-lipped. Stamens (5-) 6 or multiples of these with sessile anthers. Ovary 5-6-celled; placentation parietal or axile; ovules many, anatropous, biseriate; style divided into 3,5 or 6 linear or obtuse lobes. Seeds ± compressed, usually winged all around.

A large genus with about 400 species, chiefly distributed in tropics, represented in Pakistan by 2 native and 1 cultivated species.


Aristolochia indica 960.1753.

Hasnain & Rahman (Pl. Karachi & Sind 1:69.1957) reported Aristolochia indica L. from canal areas of Sind. This is a South-Eastern Indian species and probably their record is based on misidentification.
