 Selangor: loth mile Pahang Track (Ridley); Kedah : Gunong Jerai 

 (Ridley). Distrib. Nepal, Mergui, Borneo, Hongkong. 



A very delicate little plant occurring sporadically in dense forest. 

 If I am correct in considering all these plants as the same species 

 there is a considerable variety in the development of the wings of the 

 perianth which are somewhat large in some forms, (B. lutcscens) in 

 others almost suppressed. Miers I.e. describes the flowers as " pur- 

 purei." I have always found them white. 



6. B. OBLONGA, Ridl. Journ. Roy. As Soc. S. Br. Vol. 41, p. 33.

 i inch wide across the wings, tube narrow, wings oblong with straight 

 edges, angles rounded. Sepals and petals short blunt. Petals much 

 shorter than sepals. 



Penang on rocks at 1500 to 2000 feet alt. (King's Collector 2270) ;

This resembles B. coclestis in the form of the flower but is a 

 saprophyte. The very broad oblong wings are very distinctive.

 small not half as large. Stamens in the throat of the tube, connective 

 oblong with a tooth above and below. Style as long as the tube arms 

 short, stigmas reniform. Fruit i inch long elliptic. Seeds oval no- 

 dulose.
