This is a monotypic genus possibly endemic to Tanzania and it grows
warm and humid on cliff faces and sloping rock faces either
lithophyhtically or terrestrial. The plants have a grasslike look with a
long reedy stem and many leaves that give rise to a terminal
inflorescence at 3 feet or more high, which are induced by giving
brighter light during the early summer. If you wish to propagate this
plant leave the inflorescence on after the flowers die and keikis will
form at the nodes of the old flowers.

I copied what Jay Phal had to say about this plant as I know very little about it. Follow the stem from flower to pot in the last photo to get an idea how much gangling, rambling plant I put up with the get to appreciate that beautiful flower.
