Habenaria Willd., Sp. Pl. 4: 44 (1805).
The name Habenaria is derived from, “habena” meaning whip or strap, referring to the thread like fringes of the lip in the flowers.
This is one of the biggest genera of terrestrial orchids inn the world represented by around 800 species distributed from Tropical and Subtropical regions to South Siberia. The genus is represented by 71 species in India distributed across the landscape.
Habenaria species have small to large underground root tubers and erect stems ~10 – 100 cm length. Leaves are lanceolate or ovate, and are borne either along the stem (cauline) or only at the base (basal).
This is considered as one of the problematic group due to its complex morphology and lots of synonyms. Just the genus has around 41 synonyms. Very common indian orchid genera like Peristylus, Pecteilis, Platanthera etc have emerged from Habenaria.
I would be adding few pics from my collection of Habenaria during my next posting… Will also try to recall old posting for this eflora to make a proper set, with due credits to the respective owners of particular pictures.
Just to add, many of these pics were taken during early stages of my research when I didnt have a good camera so, please bear with the bad pictures.
