84 DENDROBIUM. 



the Botanical Magazine. This was named D. Wardianum, in com- 

 pliment to the owner, by Mr. Warner, who figured and described 

 the species for the first time, as such, in his Select Orchidaceous 

 Plants, not from Dr. Ward's plant, but from another in the collec- 

 tion of the late Mr. Day, at Tottenham, who had cultivated it under 

 the name of D. Falconeri obtusum* The long-stemmed form was 

 first introduced from Burmah, in 1875, by Messrs. Low and Co., 

 and on account of its robust growth and magnificent flowers, became 

 at once the popular I). Wardianum, which the thousands of plants 

 of the same form since imported have tended to confirm. By 

 the strict law of botanical nomenclature, the Assam form, as 

 figured by Warner, should be the typical D. Wardianum, and the 

 robust Burmese form should rank only as a variety, but the 

 exigencies of horticulture have reversed this order, especially as 

 the Assam form is more difficult to cultivate successfully. The 

 sub- variety, candidum, was introduced by Messrs. Low and Co. 

 amongst their first Burmese importations. 



D. xanthophlebium. 



Eudendrobium — Formosce, Stems tufted, 12 or more inches long, as 



thick as an ordinary writing pencil. Leaves near the summit only, 



linear-lanceolate, 2 — 3 inches long, obliquely emarginate. FloAvers in 



pairs or solitary, 1J — 2 inches in diameter; sepals and petals white, 



the former lanceolate, the latter broader, ovate ; lip three-lobed ; the 



side lobes nearly triangular, white spotted with orange ; the intermediate 



lobe sub-rotund, wavy, with an orange disc and white margin. 



Dendrobium xanthophlebium, Lindl. in Gard. Chron. 1857, p. 268. D. marginatum, 

 Batem. in Bot. Mag. t. 5454 (1864). 



Introduced by us, through Thomas Lobb (date uncertain), from 



Moulmein, whence it was subsequently sent to Messrs. Low and Co., 



by the Rev. C. Parish. It is now rarely seen in orchid collections. 



HYBRID DLNDROBIUMS. 



Hybrid Orchids, whether brought into existence by the agency of 

 Nature or by the hand of Man, have become so familiar an 

 element in almost every collection of note, that when we contem- 

 plate the great genus Dendrobium in all its aspects, it becomes 

 a matter of some surprise that so few natural hybrids, or forms 

 that would be recognised as such, have as yet made their appear-
