Harvard Pap. Bot. 7: 38. 1995. Type. China: Hainan, Mt. Jianfeng, P.-J. Lin 3938 (holotype IBSC; isotype FH).
Plants often appear coarser and more stiff-looking than the other two varieties. Stems are about 2–3 cm long and 4 mm wide with the leaves. Because of the thick and stout leaf borders, which are ca. 50 µm wide, leaves of var. pseudosinense are stiff or less crisped than those of var. collenchymatosum when dry; the cell walls of the leaf border are thick and pitted; laminal cell walls are equally thick and firm, making the cell outlines more regularly hexagonal; the leaf apical mucros of the present variety are stout and large, ca. 270 µm long.
