82 DENDR0B1UM. 



A beautiful species, abundant in many of the valleys of the 

 lower Himalayan zone. It was discovered by Dr. Wallich in the 

 early part of the present century, but not introduced to European 

 gardens till 1852, in which year Thomas Lobb collected it on 

 the Garrow Hills, at a place called Myrone, 5,000 feet above 

 sea-level, and sent it to the Exeter firm. It was shortly after- 

 wards sent to Kew from Assam, by Simons. It usually flowers 

 in March.

A curious Dendrobe, one of the very few cultivated species 



included in the section Sarcopodium, a group that imitates the 



Bulbophyls in having creeping rhizomes, two-leaved pseudo-bulbs, 



and flowers usually with narrow segments. It is a native of Borneo, 



whence it was introduced by Messrs. Low and Co., in 1881, and 



named in compliment to Mr. W. H. Treacher, the Colonial Secretary 



at Labuan.
