STUDIES IN THE COMPOSITA. 298 
lines broad, the biserial bracts equal, merely pubescent, not 
hispid; rays about 40, white, rather broad, 4 or 5 lines 
ong. 
In open pine woods of Modoc Co., California, collected by 
Mrs. R. M. Austin, Mr. M. S. Baker and others. Remark- 
able for the comparatively large and strongly 3-nerved 
leaves, which suggest those of Plantago lanceolata. 
E. Ropertranus. Roots as in the last, and general mode ; 
of growth the same; but stems only 4 to 6 inches high, 
strictly monocephalous; herbage subcinereous with a denser 
less appressed pubescence: leaves oblanceolate, obtuse, ob- 
scurely 3-nerved, the cauline linear, sessile: heads on naked 
peduncles of an inch or more; involucres broad-campan- 
ulate, their few and equal bracts slenderly acuminate, rather 
densely almost villous: rays 25 or 30, rather broad, white. 
Known only from Roberts’ Ranch, southeastern Oregon, 
Where it was collected by Mrs. R. M. Austin, in 1893. 
E.wrcRoLowcnus. Slenderly fusiform perennial root bear- 
ing at the crown a central tuft of leaves encircled by several 
slender decumbent flowering stems 6 to 10 inches high; 
herbage subcinereous with a fine appressed pubescence of 
straight hairs: basal leaves 3 to 5 inches long including the 
short petiole, linear-lanceolate, acute at both ends, entire, 
3-nerved: stems with few and rather remote sessile linear- 
lanceolate leaves: heads commonly solitary, rarely 2 or 3, 
on slender naked peduncles; bracts of the rather small in- 
voluere subequal, hispid at the very base: rays 30 or more, 
rather narrow, purplish : achenes sparsely strigose-hispid ; 
bristles of the pappus fine and fragile, subtended by an ob- 
scure short setiform outer series. 
Common on grassy plains and hills of southern Wyoming ; 
collected by the writer plentifully in meadows of Dale Creek 
in June, 1896, and in various places by Prof. A. Nelson, and 
catalogued by him as E. corymbosus, being his n. 234 from
