In M.W. (fig. 57) the leaf-blades are invariably three-lobed. The 
length may in very large leaves be 7} in., and the breadth from tip to 
tip of the side lobes 10} in.; an average length, however, is 5} in., and 
breadth 75 in. Notches with glands occur between the lobes, } to 5 in. 
from their base. In younger leaves the veins on the under side are 
often dingy purple. In older leaves the purple or red colour is 
variable in distribution and intensity, the variability depending on 
cultural conditions. 
ELOWERS. 
The flowers of B. are commonly borne singly in the axils of consecu- 
tive leaves on the young branches, and they tend to hang vertically.

FrLowerr-Bups (nat. size). 
The peduncle is triquetrous, 1 in. to 1} in. long. The odour is strong, 
and not unpleasant. . 
In C. the flowers turn upwards to the light by the bending of the 
long cylindrical peduncle (the longest 3} in.). They are produced 
singly as in B. ‘The odour is comparatively faint and decidedly 
unpleasant. 
In M.W. the face of the flowers is directed downwards at an angle 
of about 45° with the horizon. The peduncle is 1} in. to 24 in. long, 
and slightly curved outwards, cylindrical at the base and obscurely three- 
cornered distally. The odour is fairly strong and very pleasant, recalling 
that of certain Irises. The flowers are borne singly, and continue to be 
produced for several months.
