98 Nelson — New Plants from Nevada. 



Lagophylla Hillmani sp. nov. 



Annual, about 2 dm. high: stems slender, erect, simple or with a few 

 slender ascending or erect branches, sometimes branched from the base, 

 obscurely granular-glandular pubescent with a few scattered long white 

 hairs; leaves linear, thinly strigose and minutely scabrous; heads termin- 

 ating naked peduncles, rather large for the genus, 6-8 mm. high; in- 

 volucre strigose-hispid, some of the hairs tipped with black glands as 

 are also some of those on the peduncles; rays 5-6, light-yellow (?), the 

 lingule broadly oblong, 5-7 mm. long, cleft nearly to the middle into ob- 

 long obtuse lobes; disk flowers about 25, apparently all sterile; akene 

 narrowly oblong-obovate, closely enwrapped by the scarious, ciliate-pu- 

 bescent inflexed base of the involucral bracts, the upper half of which 

 is iilane and narrowly lanceolate; bracts between the ray and disk not 

 numerous. 



Not very closely allied to any species known to the writer. In aspect 

 intermediate between Lagophylla and Layia but by reason of the rays, 

 the complete absence of pappus and the abortive disk achenes will have 

 to be considered a species of Lagophylla.. 



Collected by F. H. Hillman, between Truckee and Lake Tahoe, Sept.,
