86 Rhodora [ APRIL 
bidentate,” and Æ. serotina, a plant now referred to Æ. purpurea, was 
described with * rays 2-3-dentate, spreading not dependent, shorter 
than in the preceding [ E. purpurea]? Immediately following Æ. 
serotina he characterized Æ. angustifolia, from 'Texas,with “ stem hispid, 
leaves all linear-lanceolate, hispid, entire, the radical subpetiolate, the 
cauline sessile... rays shorter than in the preceding, spreading." 
Now in view of the double comparison given by De Candolle, the rays 
of Æ. serotina shorter than in Æ. purpurea, and again those of Æ. 
angustifolia still shorter and spreading, we are hardly justified in plac- 
ing with the latter species the tall plant (Rudbeckia pallida, Nutt.) 
with long drooping rays.” 
Yet in the “ Botanical Club Check List” Dr. Britton, following 
earlier precedents of uniting as one species De Candolle's /chinacea 
angustifolia and Nuttall's Æ. pallida, took up for the two plants the 
earlier specific name fa//ida and made a new combination for them, 
D rauneria pallida, Britton. Later, in discussing his B. tennesseensis, 
Mr. Beadle interprets as true P. palida the tall plant with long droop- 
ing rays. If by Brauneria pallida is meant Rudbeckia (Echinacea) 
pallida, Nutt., this interpretation seems justified. But it is not readily 
seen upon what grounds Mr. Beadle separates his Brauneria tennes- 
seensis from the Echinacea angustifolia of De Candolle. The original 
description of the latter species agrees perfectly with the low hispid 
short-rayed plant already referred to as growing from Tennessee west- 
ward. The type of Æ. angustifolia came from near Austin, Texas, and 
we may take as representing that species in American herbaria, Mr. 
Heller’s no. 1735 from Kerrville, about eighty miles southwest of 
Austin, a plant which perfectly matches De Candolle’s description. A 
careful comparison fails to show any appreciable differences between 
this plant of Mr. Heller's and material of Brauneria tennesseensis col- 
lected by Mr. Beadle, and formerly by Dr. Gattinger at the origina] 
station near La Vergne, Tenn.
