广东玉叶金花 guang dong yu ye jin hua
Climbing shrubs, 1-2.5 m tall; branches terete, brown, densely strigillose becoming glabrescent. Leaves opposite; petiole 3-5 mm, strigillose; blade drying thinly papery, lanceolate-elliptic to elliptic-oblong, 3-9 × 1-3 cm, adaxially sparsely strigillose to glabrescent, abaxially sparsely to densely strigose or strigillose with pubescence denser along principal veins, base acute to obtuse, apex acute to acuminate with tips to 1 cm; secondary veins 3-6 pairs, apparently without domatia, tertiary venation not visible; stipules caducous, 1.5-3 mm, densely strigillose, deeply 2-lobed, lobes linear, 1.5-2 mm. Inflorescence compact-cymose to subcapitate, ca. 1 × 1-1.5 cm, few to several flowered, densely strigillose, pedunculate; peduncles 2-10 mm; bracts linear, ca. 1 mm. Flowers subsessile, biology not noted. Calyx strigillose to glabrescent; hypanthium portion ellipsoid, 2-3 mm; lobes linear, 2.5-3.5 mm, with 1 lobe on 2-4 flowers per inflorescence sometimes expanded into calycophyll, blade oblong-ovate, elliptic, or elliptic-ovate, 3.5-5 × 1.5-2.5 cm, strigillose, base cuneate, stipe 12-15 mm, apex acute to obtuse. Corolla yellow, salverform, outside strigose to strigillose; tube (31-)39-42 mm; lobes ovate, 4.5-5 mm, adaxially densely yellow papillose, acuminate. Berry not seen. Fl. May-Sep.
