Dear Manu
Habenaria furcifera is a much taller plant, in vegetative condition,
leaves are slightly scattered and you will not find a prominent margin
on the leaf, whereas in Habenaria marginatta, leaves are clustered on
the ground with distinct white margin.
In flowers, obviously furcifera is much taller with totally green
flowers, labellum is three lobed with filiform lobes centre pointing
forward and side lobes pointing backwards. In H. marginata the flower
is perfect golden yellow much shorter than furcifera and bigger too.
The labellum is three lobed which are not filiform, and the tip of
side lobed curled inwards giving a spiral look or rounded
My net is slow here so please remind me, I will share the protologues
when I come back to Dehradun.
Regards
Pankaj
