A fine species resembling B. nodosa in habit, but with 
much larger flowers, the sepals being more than two inches 
long. The lip is white, the other parts greenish. It is at 
once distinguished from B. nodosa and all the allied species 
by the firmness of the lip, which is more or less evidently 
lobed at the side, and has the veins distinctly elevated. The 
flowers are deliciously sweet at night. Messrs. Loddiges im- 
ported it from Honduras. 
The leaf is intermediate between that of Br. glauca and 
the common terete species ; and shews that in the latter the 
leaf owes its peculiar appearance in part to a general thicken- 
ing of its parenchyma, and in part to the edges turning 
inwards, meeting and growing together. And this is no 
doubt also the origin of the terete leaves found in Vanda, 
Luisia, and Dendrobium. 
It has been recommended to grow the plants of this genus
