ERIGERON IN NORTH DAKOTA 255 
watered by the James River, a tributary to the Missouri. 
A hundred miles further northward there is an ally of this 
daisy, modified as follows: 
2. Erigeron multicolor sp. nov. 
Caules 1-3, simplices, floribus 1-5 ornati, graciles, 5-30 cm. 
alti, una cum foliis tenuiter vel modice pilis mollibus repandis 
appressis vestiti. Folia radicalia spatulato-lanceolata, in petiolos 
longos alatos sensim attenuata, integra vel dentata. Folia caulina 
angusta, lanceolato-acuta, integra, inferiora saepe 10 cm. longa 
vel longiora, usque similitudinem bractearum sensim reducta, 
vel folia caulina omnia ad bracteas accedentia. Flores semi- 
sphaerei, diametro inter extremitates radiorum peripherales 2—2.5 
em., bracteis exterioribus obscuris hispidis, radiis numerosis albis 
vel rubicundis vel lavandulaceis. 
Stems 1-3, simple, 1-5-flowered, slender, 5-30 cm. high, in 
common with the leaves scantily or moderately covered with soft 
hairs, turned upwards and appressed. Radical leaves spatulate.- 
lanceolate, gradually tapering to long, winged petioles, entire 
or Gcentate. Stem leaves narrow, lanceolate-acute, entire, the 
lower often 10 cm. long or more, gradually reduced in size until 
bract-like, or all the stem leaves resembling bracts. Flowers 
hemispherical, 2-2.5 cm. in diameter between the distant ends 
of the rays, with dark, hispid outer bracts and numerous white 
to pink or lavender colored rays, often of as many different shades 
as the plant has flowers. < 
Common in moderately damp pasture land and in similar local- 
ities where the grass is scanty. I have one typical sheet of fully 
developed plants collected as early as June 8, 1901, and my second 
type sheet is dated June 24, 1906, both from Leeds, Benson County. 
I have several specimens collected within a narrow radius 
of Leeds showing a wide difference in indument, size cf plants, 
and size and color of flowers. Whatever possibilities these offer 
as new matter, they have to be corroborated by a close study of 
additional specimens to be collected during the coming season. 
The next species to be taken into consideration is 
3. Enrigeron glabellus Nutt.
