Various New Species. 
PETASITES VITIFOLIA. Leaves large, broadly cordate ovate, 
6 inches broad across the deeply cordate base, 8 inches long, sub- 
incisely and deeply 5-lobed, the one terminal and two basal lobes 
with coarse triangular teeth or secondary lobes, the others suben- 
tire, lower face of leaf thinly and only hoarily flocculent: fruit- 
ing raceme 4 inches long, rather dense, the large heads on slender 
pedicels : flowers and young foliage not seen. 
Emerson, Manitoba, 10 June, 1880, Mr. John Macoun; type 
specimens in U. S. Herb., the label without specific name; the 
cut of the large leaf intermediate between that of P. palmata 
and P. sagittata in configuration like that of the grape leaf in 
general. 
PETASITES TRIGONOPHYLLA. Leaves not large, about 4 inches 
long, nearly or quite as wide in the middle, of a peculiar trian- 
gular outline and consisting of a terminal part not larger, even 
smaller now and then, than either of the two subhastate or sub- 
sagittate-basal lobes, all three primary subdivisions deeply and 
incisely cut into triangular secondary lobes and these entire or 
toothed, upper face of leaf deep green and whitish-veiny, the 
lower thinly white-tomentose: scapes stout, covered with imbri- 
cated lanceolate bracts usually ending in a small trifid blade: 
heads many, small, subcorymbose. 
Wet meadows, Carlton Co., Minnesota, May and June, 1891, 
J. H. Sandberg, as in U. S. Herb. 
EUTHAMIA HIRTELLA. Growing in colonies; stems a yard 
high from rootstocks, striate-angled, hispidly hirtellous: leaves 
ascending, lance-linear, 3 to 4 inches long, faintly strigulose 
above, beneath almost hispidulous along the veins, the margins 
serrulate-scabrous: branches of corymbose summit fastigiate, 
strongly hispid-hirtellous: heads subsessile in glomerules of 3 
or more, the whole formed into a nearly flat-topped dense corymb: 
involucres turbinate, their bracts hardly acute, the short outer 
ones green-tipped. 
At present known only from northern Indiana, as collected by 
myself at Lakeville, 29 Sept., 1903, and by Mr. C. C. Deam in
