Ecology : Forest, shady forest in humid areas; rain-forest; sometimes in semi-deciduous forest; rather low down on tree trunks; 300-800 m alt.
  Spectacular species, distinguished by the very long slender column, as long as petals; for this reason it was first placed in the genus Barombia (monotypic). “…it is surprising that more collections have not been made. This could be an indication of it being rare throughout its range…” (Onana & Cheek, l.c.).
