Arunachal Pradesh in northeastern India hosts a diverse array of Strobilanthes Blume species. The occurrence of two previously unreported species, Strobilanthes pubiflora J.R.I.Wood and S. paniculiformis J.R.I.Wood, is documented. Strobilanthes siangensis J.R.I.Wood, Gammi & D.Borah is described as new and discussed in detail. A key to similar species is provided for identification purposes. The paper is illustrated with a map and photographs.

Strobilanthes siangensis J.R.I.Wood, Gammi & D.Borah, sp. nov.
This species belongs to the group placed by Bremekamp (1944) in his segregate genus Semnostachya Bremek., which is characterised by the spicate inflorescences in which the bracts, bracteoles and calyx lobes are all similarly linear-oblong, the bracts persistent, the stamens included and the corolla usually glabrous on the exterior. In India this group is poorly represented with only five recognised species all occurring in the northeast region (see key below). The new species is possibly most similar to Strobilanthes elongata Clarke in facies (Figs 1E, 1F) but can be immediately distinguished from this and other species in the group by its white corolla which is pubescent on the exterior.
