Description
These epiphytic herbs form distiched, hard, deeply grooved, arching leaves that are up to 17 cm long and 2 cm wide. The branched stems can grow up to 10-25 cm tall. The 20 to 50 fragrant, white, pink or blue flowers, 2.2 cm wide, are in dense, upright racemes. The spur is flat but the distal half is curved forward. [2] The chromosome count of Rhynchostylis coelestis is 2n=38.[3]
Taxonomy
The placement of this species within Rhynchostylis is further disputed,[2] although it is currently an accepted species of the genus.[1] One study identifies this species as the sister group to all other Rhynchostylis species on the basis of Amplified Fragment Length Polymorphism.[4]
Pollination
Pollination occurs during daytime through bees.[5]
