This member of the Orchidaceae family was given this name by William Griffith in 1848. It is found in the foothills of the Himalayas, growing mainly as an epiphyte with lots of water and some sun. The pseudobulbs can grow to six centimetres, the plant up to 30 centimetres. The flowers are white and maroon.
The genera name is derived from the Ancient Greek words κοῖλος (koîlos); 'hollow' and γῠνή (gunḗ); 'woman', referring to the concave stigma. The species name means 'bearded, having tufts of long weak hairs'.
