D. HILDEBRANDII (Rolfe, in Kew. Bull., 1894, p. 198) is a nearly allied 
species, which was discovered in the Shan States by H. H. Hildebrand, 
Esq., who sent plants to the establishment of Messrs. Hugh Low & Co., of 
Clapton, wherethey flowered in the spring of 1894. It has much the habit 
of D. nobile, but the flowers are light yellow, and the twisted sepals and 
petals indicate a marked affinity with D. tortile. It is a very free-growing

and floriferous plant, and as many as 1,500 flowers have been counted on a 
single clump in a wild state. In the variety oculatum there are a pair of 
maroon blotches on the yellow disc of the lip. It has yielded several 
interesting hybrids. The.first was D. Elwesii, of-which D. aureum was the 
second parent, this flowering in 1900. D. Ellisii, from D. nobile, came a 
year later, afterwards being exhibited under the name of D. Wiganianum. 
Then came D. Haywoodia, in 1902, of which D. Wardianum was the 
second parent; D. Rallianum, from D. Ainsworthii, in 1905; and D. 
Boundii, from D. Findlayanum, two years later.
