The white colored flowers of this sympodial orchid usually bloom in the months of January-May.This bushy leafless epiphyte with its inflorescence having innumerable flowers sitting high on trees being the highlight helping in identification of this species. 
The typical size of the flower is less than a centimeter in width and when observed closely the greenish lip or labellum is seen.
Usually the flowering lasts several weeks. Normally once the flowering season is complete and rains set in, the same plant can be seen full of new leaves and shoots. Typical habitat to find this species is mid to lower elevations of the Southern Western Ghats. Its also observed in other parts of India as well.
Even though this species flowers profusely, flowers being very small may be the reason behind this species being not very popular in cultivation. This hardy species once established will start flowering regularly every year or so. When it is not in bloom, with its numerous attractive canes and leaves it is wonderful orchid to grow and conserve.
