ever, impossible, as the inflorescence often stands in such a 
position that the stigma is directly in line with the falling 
pollen. The large size of the cymes and their great abundance 
render the bush very conspicuous. The odor is faint but agree- 
able. Honey is secreted in a thin adherent layer by the ovary, 
but may be observed more readily in the angle formed with 
the corolla, where it is sought by insects.

Honey is secreted by the lower part of the ovary, and there 
is a faint, rather peculiar fragrance. The stamens are 5 mm. 
in length and much surpass the stigmas. The flowers are not 
so frequently visited by insects as V. /entago. In addition 
to the list given below, two butterflies were seen at a distance 
upon the inflorescence.
