Habenaria x

[A. thom Aberdares]

I have what I belief is a Habenaria, but I don't know which specie. Sure somebody can help me out! The plants grow in a rather cool and moist climate, and even when they are submerged in the water, it doesn't seem to harm them.
The inflorescence is around 60 cm with I guess >100 flowers, which are rather green. I can image that some people find them beautiful. The first member who comes up with the right full name can collect a specimen, depending on the time of the year with seed pods. NB: I cannot see a picture of it in Orchids of Kenya, this specie mostly differs from the ones depicted that the flowers are much closer together.
