2 Muhlenbergia, Volume 6 



Almost thirty years ago I noted the striking differences of 

 habit and general aspect, between this low plant and E. Aberti- 

 anum; which latter is a tall plant, with stem simple below, pan- 

 iculate above, whereas E. cyclosepalum is invariably low, 

 branched from the very base, in no part paniculate, but with 

 every branch from base to apex leafy and floriferons, and the 

 leafage and flowering withal rather dense. The perianths are 

 larger in the species here proposed as new; but a better mark, 

 over and above the totally different habit, is the great length of 

 the oblong and leaf-like segments of the involucre. 



Excellent recent specimens of E. cyclosepalum are those of 

 E. O. Wooton, from the mesa west of the Organ Mountains, 

 New Mexico, May, 1905; also those of Wooton and Standley 

 from the same station, August, 1906. From the Black Range 

 in Sierra county, New Mexico, specimens were distributed by 

 O. B. Metcalf, under his number 1276, in I think 1904. It was 

 upon an examination of these that I decided to no longer defer 

 naming what I had for so many years seen to be an undescribed 

 member of this genus. 



Eriogoiiuiii lappulaceum sp. now 



Small annual ally of E. Abertianum about 6 inches high 

 and rather strict, the few and alternate branches in no degree 

 cymose or paniculate, ascending or suberect, the involucres race- 

 mosely or subspicately arranged: lower leaves of the undivided 

 stem rhombic-ovate to elliptic, short petioled, softly somewhat 

 villous but not hoar)': involucres few-flowered, the oblong seg- 

 ments longer than the body and often equalling the flowers: 

 outer sepals not orbicular, manifestly broader above the middle 

 than at the base, the summit almost truncately obtuse, the basal 

 lobes gradually rounded and obvious as such. 



Species of remarkable appearance as to habit; in fruit re- 

 calling some of the western forms of the genus Lappula % that is, 

 annual species like- L. occidentalism The only specimens are 

 from Camp Charlotte, Texas, by Nealley, collected in 1889. One 

 specimen of B. . Xbertianum is mounted with these on the type 

 sheet in the Y . S. Herbarium.
