206 I^HAFLETS. 



ucre subequal but in several series, their tips tapering, but 

 not attenuate nor much recurved, dark-colored and glandular 

 above the middle, but toward the base rather densely viscous- 



+ 



hirsute. 



Such a peculiar member of the group is before me, from 

 some not definitely indicated station in the mountains of 

 middle California, at 10,000 feet, by George B. Grant, collected 

 in July, 1902 ; type sheet of four specimens in U. S. Herb. 



Krigeron controversUvS. Evidently an alpine and sub- 

 acaulescent perennial, each tuft of ample upright leaves and 

 monocephalous scapiform stem arising from the branch of a 

 stout multicipitous crown, the height only iK to 3 

 leaves 1 to 1^ inches high, spatulate oblong, very obtuse, 

 entire, glabrous except as to an obscurely ciliolate margin, the 

 texture not firm ; stem with 1 to 3 linear bracts and a solitary 

 head large for the plant ; involucre between turbinate and 

 hemispherical, of not very numerous bracts and these notably 

 unequal, rather firm, linear, acute, the tips neither erect nor 

 yet definitely spreading, the whole dark-colored, glandular- 

 puberulent, with also some strigose hairs: rays broad, well 

 elongated, purple, about 25 in number. 



An ambiguous species, known to me in a half-dozen 

 specimens mounted on U. S. Herb, sheet 221514, collected by 

 Mr. Marcus Jones in Aug., 1879, at Alta, Utah. Mr. Jones 

 distributed this for an Erigeron, without any specific name. 

 It is not easy to see why in 1879, before Asa Gray had trans- 

 ferred such things from Aster to Erigeron, he should not have 

 received and distributed this plant for an aster. Perhaps the 

 only slight inequality of the involucral bracts, and their 

 glandular character, may have indicated erigeron, or, it may 

 be that the labelling and distribution of the specimens was 

 made after 1881, when Gray began to call such things erigerons 

 and therefore in the light of that author's teaching. This 

 dwarf is an erigeron only because E, salsuginosus and calhan- 

 themus are to be erigerons. If they are aster, so is this, and
