Notes. J.D. Hooker (Rec. Bot. Surv. India 4: 48. 1906) separated I. omissa from I. parvifolia based on presence of "filiform dorsal auricle of wing" in the former which is reduced to a minute appendage in the latter. But there is no consistency in that character. However, there is difference in chromosome numbers, 2n = 28 in the fonner and 20 in the latter (Virendra Kumar& Subramanian. Chr. Atlas Fl. Pl. Ind. Subc. l: 86. 1986).
