Henckelia khasiana Nampy & Akhil, sp. nov.
It is similar to Henckelia oblongifolia (Roxb.) D.J.Middleton & Mich.Möller because of its general appearance, flower colour and yellow lines on the corolla throat, but differs in the shape of the calyx lobes (lanceolate vs. deltoid), the corolla tube (two prominent longitudinal flaps on the in-ner side vs. without longitudinal flaps), the stigma (bilobed vs. obdeltoid) and capsules (tomentose vs. pubescent).
Etymology. -The specific epithet is derived from the floristically rich Khasi hills in Meghalaya, where the type locality Mawsynram is situated.
