A new species of Solanum from the Western Ghat region of Kerala, India is described and illustrated as Solanum exarmatum sp. nov. The species is dissimilar from its allied species Solanum capsicoides in terms of shape of the leaf, non spiny nature of stem and calyx in contrast to the thick armour of sharp spines in Solanum capsicoides. Spines are present occasionally on the petiole and the lower surface of the leaves but they are slender. Detailed description including distribution with relevant taxonomic notes along with colour photographs is provided.
