Notes: —De Kort & Thijsse (120: 1984) and Sanjappa (20: 1995), while revising the genus Indigofera for South-East Asia and India, wrongly gave the collection number of the lectotype specimen of I. astragalina as Perrottet 143 (G–DC). It is corrected here as 134.

Rajakumar et al. cited the type of I. karaiyarensis as follows: INDIA. Tamil Nadu. Thirunelveli district, Karaiyar , Thambaraparni upper dam, 450 m, 25 August 2010, Rajakumar et al. 2218 A, B & C (holotype JCH!; isotype MH, JCH). Even though 2218 A, B & C appear as different collection numbers, authors of the taxon personally communicated that 2218 A refers to the holotype and B & C are suffixes to the same collection number .
