Petiole 1.5-2.5 cm long. Stipules rather persistent, linear, 14-17 by 2 mm, with 2-3 narrow lobes, hairy outside. Inflorescence a leafy thyrse, c. 15 cm long, with c. 8 di-chasial to monochasial laterals of c. 4 cm long, with up to 5 flowers. Bracts c. 10 mm long, deeply incised, bracteoles 2, on the pedicel, persistent as are the bracts. Pedicels up to 1.5 cm long, densely hairy as are the other axes. Flowers bisexual, flower buds ovoid. Hypanthium cup-shaped, 7 mm across, short-woolly and with longer hairs outside. Sepals triangular, 6.5-8 by 2.5-4 mm, outer ones usually with up to 3 pairs of teeth (up to 1 mm long), inner ones entire, indumentum outside as hypanthium.
