Very young plants begin with their first two to four leaves having two or three lobes, but then have narrow elliptic leaves with entire margins,measuring 6.5 to 18 cm long and 1.3 to 2.2 cm wide. These are then succeeded by pinnate juvenile leaves that have two to nine lobes arising at 30 to 40 degrees forwards, and reach 50 cm long. They have prominent midveins along the mid line of the main leaf and the lobes. The elliptic or obovate adult leaves are 8 to 25 cm long and up to 4.5 cm wide, petiole 1.5 to 2.5 cm long. New branchlets and leaves are hairy.

Inflorescence.— Terminal tubular flowers, 10 to 52 individuals arranged in a corymb; orange–red. The pedicel and the outer surface of the perianth are pubescent.
