further complexity by Dr. Gray, 6 who, abandoning the first name 

 applied to the Rudbeckia, adopted the earlier name of Nuttall. 

 Thus the Brauneria was lost sight of and the Rudbeckia made to 

 assume a false name. Supplementing Nuttall's description of the 

 purple cone-flower, the writers notice, besides all of the characters 

 pointed out by him, a fusiform blackened root similar to those of 

 B. pallida 1 and distinct from the horizontal or horizontally-inclined 

 rootstock of B. purpurea, 1. c. The label accompanying the type 

 specimen would indicate that the original was collected in Arkan- 

 sas ; indeed, Nuttall so describes it, and a supplementary note 

 accredits the same form from North Carolina.

The notes printed above under Brauneria atrorubens expose 

 the necessity for changing the name of this southern Rudbeckia, 

 and having a number of specimens at hand collected in Florida 

 by Dr. Chapman, we venture to add to the descriptions of Torrey 

 & Gray, 1. c, Dr. Gray, 1. c, and Dr. Chapman, 1. c, as follows: 



Perennial, 6-8. 5 dm tall : stem simple, rigid, slender, striate, 

 glabrate or strigose-pubescent, prolonged into a long, naked 

 peduncle : radical leaves narrowly linear, elongated, i-3 dm long, 

 4 mm -i cm broad, rigid, 3-nerved, the lateral nerves at the extreme 

 borders of the blades, acute at the apices, narrowed below and 

 passing insensibly into apparent petioles, glabrous and glossy or 

 strigose-pubescent : cauline leaves few, similar to the radical, 

 gradually diminished in size towards the summit, where they are 

 but 2~4 cm long, the uppermost not conspicuously narrowed at 

 the base : involucres imbricated in 2-3 rows, the bracts 6-o, mm 

 long, acuminate from a broad base, smooth or nearly so above, 

 hairy below : rays 8-10, oblong, 8-1 2 mm long, deep crimson, 

 pubescent on the lower surface : disks at first hemispherical, 

 eventually oblong-ovoid, dark purple : chaff of the receptacle
