BILTMORE BOTANICAL STUDIES 



W. Letterman and Mr Henry Eggert were instrumental in bringing specimens 

 to the attention of Dr. George Engelmann, who, proposing to publish it as a 

 new species, distributed specimens to his correspondents under the name Rud- 

 beckia mis sour iensis. Dr. Gray, considering the form identical with R. ful- 

 gida Ait., evidently discouraged Dr. Engelmann from publishing the manu- 

 script. Further notes, together with a colored plate, appeared in Meehan's 

 Monthly, December, 1896. 



The writers gratefully acknowledge material assistance from Dr. James 

 Britten, of the British Museum, in the form of a tracing of the type specimen 

 of Alton's Rudbeckia fulgida. 



Rudbeckia missouriensis differs from R. fulgida Ait. u in the narrower 

 entire leaves, which are never subcordate, shorter peduncles, fastigiate branches 

 (divergently branched in R. fulgida) and the greater degree of pubescence. 



The description is drawn from material collected by Mr. George W. Letter- 

 man, at Allenton, Missouri, and distributed as R. missouriensis by Dr. Engel- 

 mann. 



The following specimens are noted : Missouri : St. Louis county, Allenton, 

 G. W. Letterman, September, 1879 ; Jefferson county, Henry Eggert, August
