can judge from an experience of a few weeks it seems to 
require a sunny station, but not a dry atmosphere. 
Mr. Bentham has pointed out its near affinity to the 
Ilhexia inaequilateralis of Schlechtendahl, afterwards called 
Plagiophyllum by him, and Centradenia by Don. Upon 
turning, however, to an authentic specimen of that plant, we 
find it different in some respects : its leaves are much larger 
and thinner, its flowers appear to he smaller, and are arranged 
in little terminal racemes much shorter than the leaves. 
Neither can this be the Plagiophyllum grandifolium of 
Schlechtendahl, which is described with leaves as much as 
six inches long. 
One of the most curious circumstances connected with this 
plant is the constant abortion, and frequent loss, of one of its two 
opposite leaves. This tendency to abortion always alternates 
along the branches, so that if the first imperfect leaf happens 
to be on the right of the branch, the next is on the left, and 
so on. The smaller leaves readily fall off, and thus the others 
appear to be alternate, as is in fact shewn by the artist who 
prepared the accompanying drawing.
