those of Heterotheca. The brush hairs (fig. 9) are arranged as in 
Heterotheca. The papille (fig. 8) are arranged similarly, but are 
longer and more acuminate. 
Aplopappus (Fig. 10, 11). 
A. racemosus (Nutt.), Torr. Style branches longer and more 
tapering than in Solidago. Stigmatic papille (fig. 11) are about 
the same shape as in So/idago, and occupy one-third of the branch. 
The brush hairs (fig. 10) are of very different lengths, the largest 
being larger than any others in the tribe. 
Bigelovia (Fig. 12, 13). 
B. nudata(Michx.), DC. Style branches slightly broader than 
in Heteratheca. The stigmatic lines occupy hardly one-half of the 
branch. The papillz (fig. 13) about as in So/idago. Brush hairs 
(fig. 12) broad and obtuse. 
Brachycheta (Fig. 14, 15). 
B. cordata (Short), Torr. & Gray. Branches of the style short 
and obtusely pointed. Stigmatic lines occupy one-third of the 
branch. The papille (fig. 15) are smaller than in Solidago. 
Brush hairs (fig. 14) broader and shorter. 
‘Bellis (Fig. 16, 17). 
B. integrifolia, Michx. Style branches essentially as in So/z- 
dago. Stigmatic lines occupy a little more than one-third of the 
branch. The papillz (fig. 17) are smaller than in Solidago, while 
the brush hairs (fig. 16) are broader and shorter. 
Townsendia® (Fig. 18, 19). 
T. eximia, Gray. Style branches long and tapering. Stig- 
matic lines occupying one half of branch. The papillae (fig. 19) 
are smaller than in So/idago. Brush hairs (fig. 18) acuminate 
as in Chrysopsis. 
Sericocarpus® (Fig. 21, 21a). 
S. asteroides,(L.) B.S.P. Styles branches very long and slender, 
about twice the length of Solidago. Stigmatic lines occupy about 
one-fourth of the branch. See figure 21 for papilla. The brush 
hairs are shown at figure 21a.
