Impatiens sahyadrica (Balsaminaceae), a new scapigerous balsam from Silent Valley National Park, southern Western Ghats is described and illustrated. The new species is phenotypically similar to I. lawsonii. However, it differs from the latter in its smaller flowers; oblong, free upwardly curved basal lobes of the lateral united petals; smaller dorsal auricle and curved spur. A detailed description, notes on distribution, biotic association and relevant taxonomic notes are provided along with colour photographs and illustrations.

2014), this genus remained unknown from the mainland India. During floristic exploration in the Idukki district of Kerala, which falls under the Anamalai phytogeographical region of the Western Ghats, we have collected a mycoheterotrophic species in the humus-rich soil in a patch of evergreen forest at medium elevation. After critical examination, it turned out to be an undescribed species of Thismia. We therefore report this finding as the first record of the genus from India and describe it as a new species here. Morphologically, the genus Thismia is characterized a reduced habit with scale-like leaves, and actinomorphic or rarely zygomorphic, urceolate to campanulate flowers. There are six perianth lobes, usually free or sometimes three inner lobes connivent at the apex forming an erect mitre with three openings (Jonker 1948).Uniquely for the genus, the new species has a mitre with only one opening, which is the major distinguishing character of the new species from other known species.
