General comments:

The place of publication given here differs from that stated in Fl. China 16: 316. 1995. The original authors published this name twice in 1979: the Fl. Yunnaica account appeared in March 1979; the Fl. Reip. Pop. Sin 64(1) account was only published in May 1979. Thus the later name is an isonym, to be discarded (K. Gandhi, pers. comm. 22 Sept. 2011).

General comments:

The taxonomy and nomenclature for this species has been greatly misunderstood and the name has been variously misapplied or reduced to synonymy. Literature relevant to the evolving taxonomic concepts over time and nomenclatural background includes C. B. Clarke (in J. D. Hooker, Fl. Brit. India 4: 211. 1885), Prain (Bengal Plts. 2: 735. 1903), Ooststroom (Blumea 3: 566. 1940; Fl. Males. Ser. I, 4: 485. 1953), Gunn (Brittonia 24: 169–176. 1972), Van Steenis (Fl. Males. Ser. I, emend. 9: 558. 1982), and Austin et al. (Brittonia 30: 195–198. 1978).

Chinese floras recognize an endemic white-flowered variety (under I. soluta). This endemic variety is known only from the type specimen; it needs careful comparison with material of bona fide I. campanulata from outside China to establish its identity. Given that the typical corolla color for I. campanulata is white on the limb and purplish inside the tube, the recognition of a variety based on corolla color seems dubious.
