This plant grows thickly on branches and trunks of trees, 
especially on the borders of mangrove swamps. The leaves 
lie flat on the rhizome, and the flowers are crowded into small 
pendulous bunches. It is quite unlike any other species from 
this region, but the flowers somewhat resemble in structure 
those of another species from Madagascar.
