D. THE PEARL," Hort. Lawrance. — A hybrid, of unknown parentage, raised 

 by Sir Trevor Lawrence, Bart. The sepals and petals are pure white with rosy 

 tips ; lip white tipped also with rose, and the throat of the deepest magenta- 

 purple. — Garden hybrid. 



^- THYRSIFLORUM, Hort. — A fine showy species, in habit like D. densiflorum, 

 but stronger, with the apex of the stems yellowish, and producing splendid 

 clusters of white flowers with a golden orange lip. There have been some large 

 importations of late, and in many cases very fine varieties have been obtained, 

 varying both in the colour of the flowers and the size of spike. This is one of the 

 handsomest of Dendroies, and is most suitable for exhibition purposes, its fine 

 drooping racemes producing a charming effect when placed beside other Orchids. 

 — Moulmein.
