Study on the Genus Drymaria (Caryophyllaceae)—A New Species from North-East India

Abstract

A new species of Drymaria from the Kohima District (Nagaland of North-East India) is described and illustrated based on both molecular data (the ITS region of nuclear DNA) and morphometric analyses (clustering, PCA, DA, and MANOVA). The new species resembles D. cordata but differs with respect to the shape of the sepal (oblong, incurved at the margin vs. lanceolate, not incurved at the margin), petals (oblong or linear vs. ovate–lanceolate), and bract (foliaceous, glabrous, non-prominent vs. non-foliaceous, pubescent, and prominent). For nomenclatural purposes, the typification of Drymaria villosa by Duke (in 1961) was corrected according to Art. 9.10 of the Shenzhen Code.
