A NEW VARIETY OF RUDBECKIA SUBTOMENTOSA. 
Eanr E. SHerrr. 
In the summer of 1910, while collecting in the immediate neighbor- 
hood of St. Louis, Missouri, the writer chanced to find a peculiar 
form of Rudbeckia. In general aspect, anise-scented involucre, etc., 
it closely resembled R. subtomentosa Pursh, a species very abundant 
in that vicinity; but in its light, greenish-yellow chaff-scales and yel- 
lowish disk-corollas, it was entirely distinct. Furthermore, extended 
observation showed that its flowers opened about two weeks later than 
did those of the species proper. 
A careful search in literature and herbaria has failed to reveal 
previous mention of this plant. But in the summer of 1911, the same 
form was found growing south of Allenton, Missouri, by Dr. G. W. 
Letterman. And during the same year, further material was collected 
in the original locality by Professor Moses Craig, of the Missouri 
Botanical Gardens. The evident constancy manifested by the form 
in its distinctive characters appears to warrant its treatment as a 
formal variety.
