Botanical Description

I. platypetala is a perennial herb that can grow up to 30-100 cm tall and it is erect or decumbent. [2]

The leaves are arranged 3-whorled but sometimes opposite, ovate to ovate-elliptical, measure 6-11.5 cm x 1-3.5 cm, attenuate at base, acute to acuminate at apex, with shallowly serrate margins and petiole 0.7-2.8 cm long . [2]

The flowers are solitary, with slender pedicel and 4-6.5 cm long. The lat­eral sepals are lance-shaped to ovate, 7-12 mm long and acuminate. The lower sepal is shallowly navicular, 8-12 mm long, abruptly constricted into a curved, with slender spur 20-40 mm long, and whitish or greenish. The petals are flat and obcordate. The dorsal petal measures 11-14 mm x 7-9 mm while the lateral petals are 19-21 mm long and they are shallow­ly emarginated. The upper pair is slightly smaller than the lower pair. The petal is pink, rose, purple, violet, white, or white with a coloured eye. [2]
