Identity of Lindernia parviflora

The name Lindernia parviflora was established by Haines (1922: 635) based on Gratiola parviflora described by Roxburgh (1819: 3) in his ‘ Plants of the Coast of Coromandel’. Before Haines (1922) two more new combinations were made by Bentham (1831 & 1846) as Bonnaya parviflora (Roxb.) Bentham (1831 : no. 3867) and Ilysanthes parviflora (Roxb.) Bentham (1846: 419) . During the present study we critically analysed the characters of L. parviflora based on the fresh specimens along with relevant literature sources. As a result, it is concluded that the morphological characters as stated in its protologue shows close similarities and falls within the range of variation seen in the widely distributed taxon, Lindernia dubia ( Linnaeus, 1753: 17) Pennell (1935: 141) . A comparison of morphological characters ( Table 2) and type specimens urges us to merge both the species. Thus we treat L. parviflora (Roxb.) Haines as a new synonym of L. dubia (L.) Pennell.
