03C7B117FFB6E74EFF621118FE87FD80.taxon	description	However, we collected one species of Aristolochia at Cikai Town (Gongshan County, Yunnan), about 30 km as the crow flies from Bingzhongluo (named Yi district in the past) where is the type locality. Except for the limb, all other characters of the collected species at Cikai Town are similar to the corresponding characters in the protologue and the type specimen of Aristolochia obliqua; limb of the collected species at Cikai Town is the same as the limb in the type specimen of A. obliqua. Hence, we conclude that character of the limb in the past publications (including protologue) was wrongly described and illustrated. Then, it is revised here as below: limb deeply 3 - lobed, slightly asymmetric, lobes triangular-ovate, straight. Detailed morphological comparison between A. obliqua and A. cucurbitoides is shown in Table 3 and Fig. 6. We also provide with the sketches mentioned above and color photos taken by us in Fig. 7. A. obliqua is also similar to A. utriformis S. M. Hwang (1981: 228) in the leaf shape, but it differs from the latter in the shape of calyx limb, which is also compared in Table 3. Specimens of A. obliqua examined: — CHINA. Yunnan: Gongshan County, 6 June 1960, N. W. Yunnan Exped. 9267 (isotype PEM), 8 May 1979, Nujiang Exped. 79 - 0054 (KUN), 8 May 2014, Z. H. Wang et al.
