Bauhinia ferruginea ferruginea

Bauhinia ferruginea Roxb. var. ferruginea

Stipules on flowering shoots early caducous; indumentum of inflorescence axis and buds usually ferrugineous; bracts pubescent, lanceolate, 5-10 mm; bracteoles smaller.

This seems to be the rarer variety, known only from S Thailand, Penang I., Perak, Trengganu, and Selangor, i. e. the northern part of the distribution area only.
