the good of other members of creation, or even for the future of 
its own race, beyond its own immediate individual interest. 
Our Rudbeckia fulgida has the general aspect of some of its 
neighbors, and especially of A. Azvta, from which however its 
smooth chaff is a good distinction. The chaff of A. Azr¢a is hairy 
at the summit. 
In his “School Botany,’’ Dr. Gray gives a list of “the com- 
monest species,” and as ours is omitted, we may regard it as 
rare. It is indeed much more limited in its geographical range 
than some of its kindred, yet one who has seen it so abundantly 
as it is found in the meadows of Eastern Pennsylvania may well 
wonder why it has not spread more elsewhere. 
Pennsylvania seems its northern limit. It extends to Central 
Ohio, and then southwesterly to Arkansas, which is its western 
line. From this it extends southeasterly to Florida, keeping, 
Professor Wood says, chiefly to the more elevated districts.
