Description from Flora of China

Didymocarpus demissus Hance, J. Bot. 21: 166. 1883; Roettlera demissa (Hance) Kuntze.

Perennials, stemless. Rhizome internodes inconspicuous. Leaves basal, opposite; petiole 0.5-3 cm X 1-3 mm; leaf blade elliptic to narrowly ovate or narrowly obovate, 2.5-5(-7) X 1-2 cm, papery, adaxially densely puberulent and villous, eglandular, abaxially grayish velutinous to densely pubescent, base cuneate to broadly cuneate, margin entire, apex acute to rounded; lateral veins ca. 3 on each side of midrib, inconspicuous. Cymes 1-3-flowered; peduncle ca. 6 cm, densely pubescent to villous; bracts 2, free, triangular-linear, ca. 2 X 0.3 mm, pilose, margin entire, apex obtuse. Pedicel ca. 5 mm, densely spreading pilose. Calyx 5-sect from base; segments equal, lanceolate-linear, 4-5 X 0.8-1 mm, outside densely pilose, inside above sparsely pubescent, margin entire, apex acute. Corolla white, ca. 2.3 cm, outside sparsely puberulent, inside glandular puberulent near mouth; tube narrowly funnelform, 1.5-1.8 X ca. 0.5 cm; adaxial lip ca. 4 mm; abaxial lip 8-9 mm. Filaments ca. 6.5 mm, pilose basally, pubescent above; anthers fused by entire adaxial surfaces, ca. 3.2 mm, abaxially pilose; staminodes absent. Pistil ca. 1.5 cm, puberulent; ovary ca. 5.5 mm. Stigma narrowly oblong, ca. 1 mm, undivided. Capsule erect, ca. 5 cm. Fl. Oct.

This species was previously placed in Didymocarpus. It is currently included in Chirita because its stigma is abaxial and oblong. In Didymocarpus, the stigma is terminal and capitate or discoid in shape, probably formed by fusion of the adaxial and abaxial stigmas.

After publication of the family treatment for the Flora of China, this was treated as Primulina demissa (Hance) Mich. Möller & A. Weber (Taxon 60: 781. 2011).
