26 PITTONIA. 
light-green : leaves narrowly linear, acuminate, rather strongly — 
punctate, l-nerved, glabrous on both faces, scarcely even the 
margins scabrous: heads as long as in Æ. leptocephala but nar- 
rower; bracts of the inyolucre firmer more obtuse and more 
glutinous: rays 10 to 12, long and narrow ; disk-flowers 4 to 6 — 
Sapulpa, Indian Territory, 6 Oct., 1894, B. F. Bush. Type 
in the herbarium of the writer. Very different from Æ. leptoce- — 
phala, and in aspect strongly recalling the Mexican genus Gym 
nosperma. Among the Futhamia sheets of the U. S. Herbarium, I 
find the following to be referred to Z. gymnospermoides : one from 4 
the “ Cherokee Nation ” by Blankinship, 15 Aug., 1895: another — 
collected very long ago, by Bigelow, this from the “ Antelope 
Hills of the Canadian.” It was listed in Whipple’s Report as 
Solidago tenuifolia. ; 
E. CHRYSOTHAMNOIDES. Near EZ. gymnospermoides but the i 
branching more fastigiate and inflorescence more corymbose; | 
leaves as narrow and as firm, similarly impressed-punctate, morë 
strongly and carinately 1-nerved beneath, the margin definitely _ 
scabrous-serrulate ; heads more elongated and more distinctly 
turbinate, their firm bracts more obtusely green-tipped, gla- 
brous, except that the inner are ciliate with a few long bristly — 
hairs. ; 
Species well enough marked, though known in but a single © 
sheet of specimens preserved in the U. S. Herbarium. They | 
are mere flowering branches, and were collected near Prescott, ‘ 
Arkansas, 25 Aug., 1882, by G. W. Letterman. 
E. CAROLINIANA, Greene, Mem. Torr. Club, v. 321. Hrigerot 
Carolinianus,Linn. Sp. 863. In so far as it is connected with a f 
low plant with a corymbose mode of branching that is commo — 
both at the North and the South, the above name is misapplied. a 
A critical enquiry into the originals of Erigeron Carolinanus; i 
Linn. reveals conclusively the fact that it is a plant exceedingly | 
unlike the Solidago tenuifolia of Pursh, with which all authors | 
for eighty years past have blindly agreed in confusing it f
