Different specimens of this plant vary much in appearance, as the stems which 

 spring up after the annual tires are shorter, stouter and less leafy than the earlier and 

 more normal leafy growth. Pax describes the involucres of E. trichadenia as pilose, 

 but the pubescejice on the tyi)e specimen consists of miniite spreading hnirs, scarcely 

 visible to the naked eye. It varies considerably in different specimens, even in the 

 same gathering, and usually the involucres are glabrous. 



50. E. ledenuanniana, Pax d: Iloffm. in Emjl. Jahrb. xlv. 241. 

 Stems annual from a perennial rootstock, o-8 in. high, about 1 lin. 

 thick, herbaceouti_, usually forking into a 2-branched cyme at the apex, 

 simple or rarely branched below, glabrous. Leaves alternate on the 

 simple part of the stem, opposite at the base of the cyme and on its 

 branches, sessile or subsessile, \-''^>\ in. long, M-5 (or those at the flower- 

 ing nodes sometimes 6-7) lin. broad, linear-lanceolate, acute, coriaceous 

 or perhaps somewhat fleshy, with cartilaginous entire margins, not 

 keeled on the midrib beneath, often longitudinally folded, glabrous on 

 both sides. Sti})ules none. Cyme-branches J-3 in. long, each with 1 

 terminal involucre and sometimes one or two others scattered along 

 them and 1 in the fork between them at their base, glabrous. In- 

 volucres '.)\-^ lin. in diam., cup-shaped, glabrou.s, "yellowish-green'" 

 {Lederinanii), with 5 glands and 5 erect subquadrate minutely crenulate 

 lobes; glands erect in dried specimens, ]J- lin. in their greater diam., 

 transversely subrectangular, minutely crenulate on the outer margin, 

 rugulose on the flat inner surface, with a slightly raised ridge at the 

 lower or inner margin. Ovary subglobose, glabious, exserted on an 

 erect pedicel ; styles about 1 lin. long, shortly united at the base, then 

 spreading-recurved, 2-lobed at the apex.
