The botanical name of this weedy herb was indicated as Lindernia sessiliflora in the reference booklet "A Guide to the Wildflowers of Singapore" published by Singapore Science Centre back in 1985. However, Lindernia sessiliflora appeared to be the synonym of Lindernia nummulariifolia. When I checked the pictures of Lindernia nummulariifolia in the Internet, they seemed to show a different plant. Further search landed me on a creeper named Lindernia diffusa that looks similar to my pictures. | Reference |
