Trigonotis Stev. (Boraginaceae-Eritrichieae), occurring in Asia and temperate Melanesia has about 35 species. The area taken up for revision is India, including Sikkim and Bhutan. C.B. Clarke (1883) described 5 species from this area. Since then one species and a variety have been added to the list of Indian Trigonotis, by nomenclatural transfers (Johnston, 1925), and T. gracilipes Johnst, a Chinese plant, has also been reported from Sikkim (Johnston, 1937). The author now adds two more species, T. caespitosa Banerjee, T. smithii Banerjee and one variety, T. multicaulis Benth. ex Clarke var. cavei Banerjee, which are new to science. These new taxa are described here.

Efforts have been made to give full descriptions and synonymy of the other taxa taken up for revision, along with a workable key. Nomenclature has been checked and revised wherever necessary.
