BULBOPHYLLUM LEYSIANUM, Burbidge. 



Mr. Burbidge, in his paper on " Botanical Exploration in 

 Borneo," mentioned this remarkable Bulbophyllum (p. 55), 

 which we could not trace as being described in any botanical or 

 horticultural work at our disposal. He has now kindly supplied 

 the following additional information, in addition to the drawing, 

 which is reproduced in the accompanying woodcut : — 



Bulbophyllum Leysianum, Burbidge, sp. nov. — Plant 

 epiphytal, 7 or 8 inches high ; pseudobulbs ovoid, tetragonal, 

 1-1 1 inch long., Leaves coriaceous, lanceolate, glossy, 4-8 inches 

 long. Flowers solitary, on scapes 5-7 inches long, and 

 furnished with three or four bracts. Dorsal sepal soft yellow 

 with purple veins, broadly ovate, arching or hooded, with 

 chequered venation. Lateral sepals pinkish, united or connate, 

 with purple lines near the base. Petals whitish with green 

 veins, ovate 3-nerved, prolonged into a thread-like point, tipped 

 with a hairy or pilose glandular apex. Column white, anther 

 green. Lip entire, fleshy, curved, yellow or amber-coloured, 

 densely covered with a velvety pile of a purple-red colour. 



Habitat on trees overhanging the river near the ford at 

 Sinaroup village, N.W. Borneo. 



This is a very distinct species, the great dorsal sepal being- 

 hooded and translucent in a manner reminding one of the 

 hooded pitchers of a Darlingtonia or Sarracenia. At the first 

 glance there is something suggestive of some South American 

 Masdevallias in the general aspect of the plant. The specific 

 name is given in compliment to the Hon. P. Leys, M.B., late 

 Col. -Surgeon of Labuan. — F. W. B.
