A New Record of Capparis (Capparaceae) from Taiwan: Capparis sabiaefolia

People in Taiwan have identified Capparis sabiaefolia Hook. f. et Thoms. as Capparis acutifolia Sweet. In this paper we clarify the identity of C. sabiaefolia for the flora of Taiwan and further document C. acutifolia in Taiwan. C. sabiaefolia was characterized by branchlets without thorns; leaves thinly herbaceous leaves, 7.5-10 cm long, base rounded, veins obscure on both sides; and densely tomentose on inner surface petals. C. acutifolia was described as branchlets with thorns; leaves coriaceous or thinly coriaceous, 9-16 cm long, base acute, veins distinct on both sides; and petals glabrous but tomentose at the margin.
