The new species Reineckea flava J. Z. Dong (Liliaceae) is described and illustrated from Guangxi, China. It differs from R. carnea (Andrews) Kunth in having slanting rhizomes with short oblate internodes (shorter axis 4–6 mm × longer axis 8–14 mm), with thick and short adventitious roots at nodes, narrowly lanceolate leaves (5–10 mm broad), and yellow-orange fruits.
