There are apparently two distinct races in Aeschynanthus bracteatus which have been called varieties. We do not consider the distinctions strong enough to recognize taxonomically; however, in SE Yunnan there is a race which can usually be distinguished from typical A. bracteatus. This race usually has leaf blades broader (elliptic to oblong or obovate) and thicker (leathery), and which dry flat adaxially and frequently abaxially cinnamon reddish. In contrast typical A. bracteatus specimens have leaf blades lanceolate to narrowly ovate and thin leathery to papery which dry rugose adaxially and abaxially usually yellowish green.
