Aristolochia hainanensis subsp. yingjiangensis X.X.Zhu & J.S.Ma View in CoL , subsp. nov. ( Figs. 4 A–E View FIGURE 4 & 5 View FIGURE 5 )
The new subspecies differs from A. hainanensis Merrill (1922: 341) by its suborbicular lamina (base shallowly cordate to cordate), and bigger fruit (15–20 × 4–5 cm). It is also similar to A. kwangsiensis Chun et How ex C.F. Liang (1975: 12) in the leaf shape, but it differs from the latter in the shape of calyx limb. Detailed morphological comparison is shown in Table 2 and Fig. 4 View FIGURE 4 .
