Epiphyte as well as lithophyte. Always in clusters with pseudo-bulbs crowded together forming dense turfs. Bulbs very small, ovoid less than 1 cm long. Leaf solitary, linear-lanceolate, acute, the base narrowed to the petiole 5 to 8 cm long and less than 2 cm in width. Scape much shorter than the leaves, slender, erect, minutely bracteate, bearing at its apex 3 to 7 flowers in an umbel. Flowers bright yellow throughout with slight ocherous tinge here and there. Dorsal sepal free at its base from the lateral pair, very concave, vaulted over the column, ovate, shortly acuminate. The lateral pair much longer than the dorsal, linear lanceolate, partly coherent, the bases and apices free. Petals broadly ovate, acute. The margins of petals and sepals are teethed. Lip oblong, sub-acute, entire, fleshy, very concave near the base.
A very small plant, found specially on rocks attracts attention with its cluster growing nature. Found few clusters on rocks and on trees around a sub-tropical habitat. Identified as Cirrhopetalum caespitosum, Wall. ex Lindl (Bulbophyllum scabratum Rchb.f.) with its cluster growing property. Waited till the summer months to document it in bloom. The route through its habitat was used frequently by me for other surveys in the region, so at least visited the plant twice a week during the summer months. After seeing them in buds, the anxiety level to shoot them in bloom made my visiting frequency go up. However, I never took more tension on this particular species as there were a few clusters around that region. If I miss one in bloom I can zero on another one. It started blooming by the mid Summer and initially it seems the flowers are very small, so waited for a full grown cluster to bear healthy flowers and got this wonderful photograph.
