1892.] Development of the Fiower. 357 
hairs are detected; these comprise stigmatic papilla and brush 
hairs. The former are usually short, being either acutely or 
obtusely tipped, and are confined to the inner faces of the 
style-branches. The latter are cylindrical, epidermal out- 
growths, having various arrangements both on the inner and 
outer faces of the style-branches. In the Asver the style- 
branches are flattened, and linear from their bases to the ends 
of the two lines of papilla which line each stigmatic surface. 
Above the termination of the stigmatic lines are seen brush 
hairs which cover both faces of the style branches. In the 
Solidago the style-branches very much resemble in outline 
those of the Aster. Two stigmatic lines are observed which 
extend from the base of the branch to a point about one-half 
the distance to its tip. The brush hairs usually cover the 
whole outer surface of the branch, and the edges and the tip 
of the inner face above the termination of the stigmatic lines.
