It was claimed as a new species with a published photograph of an inflorescence (with three flowers) and brief information on its habit, habitat and phenology in a leaflet during a seminar organized by Department of Botany, Nagaland University on 20 th April, 2009. The leaflet is also available online at «http://www.nagauniv.org.in/menu/ events/SAP_SEMINAR_ 20April2009.pdf» and a photo-plate of <i>C. mohanramii</i> has also been deposited in CAL. However, the name <i>C. mohanramii</i> does not fulfill the conditions of an effective and valid publication as it lacks Latin diagnosis or description and type (s). After the study of dissected floral parts (photographs) of ‘ <i>C. mohanramii</i> ’ sent by Dr. C. Sathish Kumar, it is found identical to <i>C. griffithii</i>. In this circumstances <i>C. mohanramii</i> does not require to be validly published.</p>Published as part of <i>Bhattacharjee, Avishek, 2012, On the status of some species of Cheirostylis Blume (Orchidaceae) from India, pp. 31-35 in Candollea 67 (1)</i> on page 34, DOI: 10.15553/c2012v671a3, <a href="http://zenodo.org/record/5708655">http://zenodo.org/record/5708655</a&gt

Two Frequently Confused Species of 'Jewel Orchid' (Orchidaceae - Goodyerinae) from India

Zeuxine goodyeroides and Zeuxine nervosa are two distinct species of terrestrial orchids but confused and misreported in some recent Indian literature. The present communication emphasizes the need of study of type specimens for fixing identity of species. A mistake repeated several times will have a chance to obscure the correct identity of a species
