An identification key to all the reported species of Hedyotis-Oldenlandia group (Hedyotis, Oldenlandia, Exallage, Leptopetalum, Scleromitrion and Debia) in Andaman & Nicobar Islands is presented with one new species, Oldenlandia smita-crishnae, described from Saddle Peak forests of North Andaman, India. It shares some characters with Oldenlandia herbacea, O. corymbosa and O. pseudocorymbosa. However, it is remarkable for its abaxially puberulous leaves, divaricate stipules, ellipsoid to obovoid hypanthium, pink-striped corolla lobes and 20–30-seeded, inserted capsule. Furthermore, a new combination in Exallage is proposed and lectotypes for Spermacoce cristata, S. costata, Hedyotis vestita and Oldenlandia stocksii are designated.
