EXPLANATION OF PLATES. 
All of the illustrations are from herbarium specimens un- 
less otherwise noted; herbarium sheets are uniformly reduced 
to one-third natural size; details are of natural size. For 
the habit figures I am under great obligation to the gentle- 
men whose names are mentioned in connection with the ex- 
planation of them. On the distribution map, the localities 
at which collections have been made are marked by circles 
accompanied by indicative letters that are referred to in the
