Abstract
Aeschynanthus wangii Y.H.Tan & H.B.Ding, a new species of Gesneriaceae from Yunnan Province, China, is described and illustrated here. The new species morphologically resembles A. angustioblongus W.T.Wang and A. stenosepalus J.Anthony, but is significantly different from them by having lanceolate leaves with long caudate apex, brownish yellow corolla with five dark red lines from the middle of corolla tube to the top of the lobes, and calyx lobes slightly fused into calyx tube (2–4 mm) at the base.

Diagnosis: Aeschynanthus wangii resembles A.
angustioblongus W.T.Wang (in Wang 1975: 64) (Fig. 2B)
in having lanceolate leaves and solitary flower in leaf
axils, and also shares similar characteristics with A.
stenosepalus J.Anthony (in Anthony 1934: 191) (Fig. 2C)
in having lanceolate leaves with long caudate apex.
However, the new species can easily distinguished from
others by its leaves with long caudate apex (vs. obtuse in
A. angustioblongus), absence of peduncle (vs. 2.2–5(–7) cm long in A. stenosepalus), corolla brownish yellow
with five dark red lines from the middle of corolla tube to
the top of the lobes (vs. red, in A. angustioblongus and A.
stenosepalus) and calyx lobes slightly fused into calyx
tube (2–4 mm) at the base (vs. free to bottom, in A.
angustioblongus and A. stenosepalus).
Etymology: The specific epithet wangii honors Prof. Wen Tsai Wang (W.T. Wang, 1926–2022), who made significant contributions to the Flora of China.
