At first sight this plant and the type seem very unlike, but close examination reveals 
so many points of agreement that I refrain from making two species of them. The 
specimens which have served for the description of the type are small pieces hastily 
gathered, on our way up to Cuyaba, at one of the log-cutting settlements; hence they 
probably do not do full justice to the species—an additional reason, this, for the course 
here taken. The difference in time of flowering of type and variety is noteworthy. 
In the description of the length of the staminal tube (in species of Pavonia) I have 
measured only the distance between its bottom and the point whence the first batch of 
stamens is given off. [ Bras. Or.]
