Rounded-Lip Zeuxine is a terrestrial herb, upto 16 cm
tall, rhizome forming. Flowers are borne in a laxly 2-5
flowered raceme at the top. It shows close resemblance with
Zeuxine longilabris but
can be easily distinguished mainly in having ovate-lanceshaped lateral
sepals; broadly elliptic petals with rounded tip and lip lobes with
entire margins as compared to ovate-oblong to awl-shaped lateral
sepals; oblong-sickle shaped petals with almost pointed to blunt tip
and sawtoothed epichile margins of the latter. Although the degree of
serration of lip margin varies in Zeuxine longilabris, but it
is never entire. Further, the color of sepals of Zeuxine
chowdherii is pinkish-red whereas in Zeuxine longilabris it
varies from greenish-white to greenish-brown. Rounded-Lip Zeuxine is
found in Southern Western Ghats, at about 1200 m altitude.
