iiupsis, are often out of all proportion to the number and strengtli 

 of the leaves. The species succeeds under the same treatment 

 as Burlingtoniaa or the more delicate kinds of Onddivm, and 

 should be placed either on a block of wood, or, what is far better, 

 on one of those earthenware imitations of a block of wood to 

 which the name of " branch-orchid pots " is now applied. 



Descr. Leaves thick and channeled, two or three clustered to- 

 gether, linear-lanceolate, keeled, about six inches long. Scape 

 panicled and spreading a foot or more long, loaded with almost 

 innumerable flowers of delicate and beautiful texture. Sepals 

 sharp-pointed, scarcely more than the eighth of an inch long. 

 Petals rather wider than the sepals, but otherwise conformable to 

 them, white. Lip very large, pubescent at its base, and with 

 two-lobed, rounded, apiculate limb, almost entirely white in some 

 varieties, while in others it bears on its disk either a patch of 

 yellow or of purple, or of both combined. Here it has two thin 

 rounded auricles within the edge of the lip, and two much more 

 fleshy calii within the auricles themselves. Column upright, 

 short, wingless. — /. B.
