SoLIDAGO HUMILIS Pursh. In 1908 the writer! pointed out that 
the type of S. humilis Pursh ? is a Newfoundland plant in the Banksian 
Herbarium, which is quite unlike the species (S. racemosa Greene) 
with which it was long identified. In the discussion of S. humilis 
seven years ago the exact identity of Pursh’s species was left unsettled, 
but the statement made that it was either S. uliginosa Nutt. or S. 
uniligulata (DC.) Porter. At the same time it was pointed out that, 
as soon as its exact application should be determined, the name S. 
humilis Pursh must be taken up for one or the other of the two later 
species; and that those authors who had set aside the name S. humilis 
Pursh (1814) on account of a supposed earlier “S. humilis” of Miller 
(1768) could not have verified their references, for Miller had pub- 
lished, not “S. humilis” but S. humilius,3 a name in the comparative 
degree (neuter) and certainly not the same name as S. humilts. 
The recent collections from Newfoundland, Gaspé and the Labrador 
Peninsula have brought in a large number of sheets of Solidago uligi- 
nosa Nutt. Journ. Acad. Philad. vii. 101 (1834) and there is no question 
that the type of S. humilis Pursh is a small northern specimen of this 
species. It is perfectly matched in stature, habit, foliage, and even 
in the elongate leafy bract at the base of the slender interrupted 
thyrsus by such specimens as Spreadborough’s no. 14324 from the 
Ungava River, Robinson & Schrenk’s no. 210 from the Exploits River 
in Newfoundland, Fernald & Wiegand’s no. 4098 from the shores of 
Ingornachoix Bay in Newfoundland, and Fernald & Collins’s no. 768 © 
from Table-top Mountain, Quebec. There is, then, no question that 
S. humilis Pursh (1814) is S. uliginosa Nutt. (1834). Although vary- 
ing greatly in stature and in the size of the inflorescence S. humilis 
has the cauline leaves bluntly acuminate or at most acute, the rhachis 
and branches of the thyrsus at most short-hirtellous and the bracts of 
the involucre obtuse. About the ponds of the East Branch of the 
Humber in Newfoundland occurs a plant like S. humilis in habit and 
inflorescence but so far departing from it in details as to merit separa- 
tion as 
S. numris Pursh, var. peracuta, n. var., foliis caulinis serratis apice 
subulato-attenuatis; ramis hirsutis, pilis 0.5-1 mm. longis; involucri 
bracteis attenuatis. 
Cauline leaves serrate, the apex subulate-attenuate; branches
