Abstract

A species new to science, belonging to Strobilanthes from Thailand is described. Strobilanthes sirindhorniae Kladwong & Chantar., sp. nov. is found on limestone in northern Thailand. It is morphologically similar to S. maxwellii J.R.I.Wood and S. rosea Nees. A comparison table with similar and closely related species and a distribution map, and an illustration of S. sirindhorniae sp. nov. are provided.
