Abstract

Four ‘abnormal’monotypic sections were published by Hooker in Habenaria. Three of them, namely, Diphylax, Dipyla and Dithrix were upgraded subsequently as three independent genera, viz., Diphylax, Ponerorchis and Dithrix respectively. The fourth section, Plectoglossa, represented by endemic (Western Ghats) Habenaria perrottetiana, is collected and studied in detail and presented it now under a new genus, Plectoglossa. Its diagnostics, distribution and conservation status are presented. A key to all 4 related genera and a review on their current status is given.
