Geranium sect. Lucida

Mericarps were 1.9–2.1 × 1.0– 1.2 mm and brown in color. The surface was rugose and gemmate-micro-echinate with 3 longitudinal ribs in the dorsal surface and 2 apical stiff ridges. Mericarps have a row of hooked non-glandular hairs on the margin, despite glabrous surface of other parts ( Fig. 7, I 1–I 2).
