1924] Fernald,—Some Senecios of Eastern Quebec 115 
while others are inseparable in foliage, involucre and disk-corollas 
from material collected by Charles Wright on Arakamtchetchene 
Island in Bering Straits or by Blaisdell at Cape Nome; while taller 
and looser-growing individuals are almost identical with Weinmann’s 
specimens from the Kuskokwim Valley in Alaska. The only difference 
I can make out is that the material from about Bering Sea usually 
has well developed rays; the Newfoundland plant is usually discoid, 
though occasionally with short ligules; but the ligules of the Chamisso 
material are nearly as short as in the radiate plants from Newfound- 
land, while S. resedifolius, var. columbiensis Gray is a lax and luxu- 
riant shade-form separated because of its rayless heads. I am, 
therefore, unable to find any stable characters by which S. Fernaldii 
can be maintained as specifically distinct from S. resedifolius. 
During the summer of 1923, the party! exploring the schistose 
mountains centering on Mt. Logan in Matane County, Quebec, found 
a very handsome Senecio with large commonly solitary and radiate 
heads. This plant (figs. 1', 1? and la), which abounds in turfy 
chimneys and upon cliffs and talus at altitudes of 850-1150 m. on 
Mts. Fortin, Logan and Pembroke, and which in its well developed 
green leaves (basal leaves up to 3 cm. broad, cauline leaves in luxuriant 
plants up to 8 em. long and 3.5 em. broad), tall stature (often 2-3 
dm.) and showy elongate ligules, did not suggest in the field the little 
purplish plant of the dry barrens of western Newfoundland already 
discussed; but at one station, the dry upper talus and cliffs at the 
head of Hanging Valley on Mt. Pembroke, plants clearly conspecific 
with the large-leaved specimens of the moister chimneys had the low 
stature, reduced foliage and occasionally the discoid heads of the 
Newfoundland plant. Altogether the plant of the Shickshock Mts. 
shows almost every conceivable variation, even for so protean a group 
as Senecio, and in this series collected at three closely adjacent stations 
all the recorded variations of S. resedifolius can be matched. 
The variation of S. resedifolius which was described by Ledebour 
from the Altai as Cineraria lyrata is so much taller and has so much 
better-developed basal leaves than Chamisso's plant that it has been 
treated by DeCandolle, Herder and others as a distinct variety, var. 
lyratus (Ledeb.) DC., supposed to be confined to the Altai and Baikal 
region; but some of the individuals from the Shickshock Mts. are 
! J. F. Collins, C. W. Dodge, M. L. Fernald, Ludlow Griscom, K. K. Mackenzie, 
A. S. Pease and L. B. Smith.
