gently spineseent-tipped: involucral bracts narrow, acute, glandular- 

 puberulent : corollas yellow. 



Species known only from Monterey, California, where it has been 

 collected in recent times by Parry, Pringle, Tidestrom and others, 

 but earlier, as shown in the herbarium at Kew, by Hartweg. In 

 the American herbaria it is found mixed sometimes with L. germano- 

 rum, sometimes with L. glandulifera.. 



Pyrrocoma eriopoda. 



Caudex ligneous, covered with a dense white wool connected with the 

 bases of the petioles of the oblong lanceolate obtuse coarsely toothed 

 coriaceous glabrous or minutely scabrous leaves ; stem erect, rigid, 

 1 to 2 feet high, with a few ascending or suberect branches; cauline 

 leaves spatulate, the rameal ovate, acute, remotely serrate, less 

 than 1 inch long: heads solitary on the ends of the branches and in 

 the axils of the leaves; involucres turbinate-campanulate, about $ 

 inch high; bracts very rigid, oblong linear, green throughout, but 

 more herbaceous at the erect pungently acute apex: rays 15 to 20, 

 not showy. 



Collected at the Soda Springs, Esmeralda County, Nevada, July, 

 1888, by Mr. Shockley. 



Pyrrocoma solidaginea. 



Stems rather stout, decumbent, 12 to 18 inches high, lanuginous- 

 tomentose throughout, but the leaves, and often all but the base of 

 the stem ^labrate at maturity: radical leaves lanceolate, on rather 

 slender petioles, 2 to 5 inches long, entire or irregularly serrate, 

 abruptly acute; cauline spatulate, sessile by an auricu late-clasping 

 base: stem parted at the middle or toward the base into numerous 

 slender suberect branches bearing numerous raoemosely disposed, 

 small heads : involucres campanulate, 1 inch high ; bracts imbri- 

 cated loosely in about 3 series, linear, or oblong- linear, the green- 

 herbaceous erect tips pungently acute: rays 12 to 18, small, light 

 yellow. 



Along the Humboldt River, at Palisade, Nevada, 24th of July, 

 1893. Species much resembling a Solidago; the small heads not 

 rarely numbering as many as seventy-five on a single stem. 



Pyrrocoma subviscosa. 



Steins not rigid, 14 to 20 inches high, only slightly decumbent: 

 leaves, upper part of stem, and the inflorescence glandular-puberu-
