D. crystallinum was discovered by Col. Benson, F.L.S. in 
Birma, and introduced by Messrs. Yeitch, wlio first flowered 
it. The Royal Gardens are indebted to Messrs. Low for a 
fine specimen of it, which flowered freely, and the drawing 
was made from a plant in Mr. Bull’s nursery in June, 1874. 
Descr. Stems tufted, terete, slightly flexuous, grooved, 
one third of an inch and upwards in diameter, a foot or more 
long, internodes about an inch long ; clothed with closely 
appressed membranous striate pellucid sheaths, the rounded 
tops of which project about one quarter of an inch beyond 
the nodes. Leaves on flowerless stems, distichous, four to 
six inches long, linear-lanceolate, acuminate, membranous, 
bright pale-green. Flowers in pairs on very short peduncles 
from all the upper nodes, two inches in diameter ; bracts one 
quarter of an inch long, lanceolate ; pedicels slender, nearly 
an inch long; ovary small. Sepals and Petals spreading 
widely, white, with pale rose blotches at the tip, margins 
somewhat waved and recurved ; sepals linear-oblong, acute ; 
petals broader, more obovate, and obtuser. Lip with a short 
convolute claw and circular expanded limb, which is in- 
flexed at the base forming two auricles, margin ciliolate, sur-
