Abstract
Primulina adenopoda (Gesneriaceae) is described and illustrated here. This new species resembles P. yangshanensis W.B.Xu & B.Pan and P. depressa (Hook.f.) Mich.Möller & A.Weber in leaf blade shape, corolla tube shape, and corolla color; phylogenetic analysis shows it is closely related them too, but it is distinct from them by indumentum characters, bracts number, corolla tube size, and placenta type. The conservation status of P. adenopoda is assessed as "Near Threatened" (NT) according to IUCN Red List Categories and Criteria.

Primulina adenopoda G.L.Xu, sp. nov.
Diagnosis: Primulina adenopoda are similar to P. yangshanensis and P. depressa morphologically. However, it can be easily distinguished from P. yangshanensis by its corolla tube 3.7–4.1 cm long, with a yellowish-brown mark between two adaxial lobes inside (vs. 1.4–1.7 cm long, without mark in P. yangshanensis, following order same); bracts 3 (vs. 2); filaments sparsely glandular-puberulent (vs. glabrous). It differs from P. depressa (Hance, 1883; Wang et al., 1990, 1998; Li and Wang, 2005; Weber et al., 2011) by parietal placenta (vs. axile placenta in P. depressa, following order same); bracts 3 (vs. 2); filaments sparsely glandular-puberulent (vs. glabrous).
Etymology: The petiole of this new species covered with dense pubescence and intermixed with glandularpubescence, so the specific epithet is derived from the indumentum characters of petiole, namely "adenopoda".
