minute flowers, as I have never found them contain more than three seeds, 
and, as a rule, one or two only. The capsules of the small flowers yield 
three and four. The minute and closed flowers of these species have a 
reddish-tinged corolla about a line lon ng, and nearly equally divided be- 
tween the tube and the limb, the latter consisting of four nearly equal concave 
lobes, bilabiate in the ud; he stigma rests between the anthers, and 
as these have dehisced before the corolla opens or falls off, self-fertili-
