 brous, and with some hispid hairs, above more or less glandular : leaves alternate, narrowly 

 linear, with revolute or involute margins when dry, entire : heads short-peduncled, terminat- 

 ing the paniculate branchlets, 3 to 5 lines high : both rays and disk-flowers white : anthers

• § 1. Madakia. Ligules exserted and conspicuous: disk-flowers sterile or 

 partly fertile : disk-corollas pubescent, except in the first species : herbage hir- 

 sute, the upper part minutely glandular. — Gray, Proc. Am. Acad. ix. 188, & 

 Bot. Calif, i. 358. 



* Annual, low and slender, with mostly alternate leaves and small heads : pappus both to ray and 

 disk-flowers ! 



M. Yosemitana, Parry. A span or more high : leaves linear, entire : heads slender- 

 pedunculate, 2 lines high : ray-flowers 5 to 10, with ligules a line or two long: disk-flowers 

 3 to 10, sterile : corollas nearly glabrons : bracts of the involucre with short and narrow tips ; 

 of the receptacle 4 to 8, more or less connate by their margins : ray-akenes semi-obovate or 

 slightly lunate, bearing an evident pappus in the form of a ciliolate crown : pappus of the 

 disk-flowers of about 5 sparsely barbellate awns, nearly equalling the corolla. — Gray, Proc. 

 Am. Acad. xvii. 219. — California ; near Fresno, Eisen ; at' the foot of the upper YoSemite 

 Fall, Parry (few-flowered form) ; near Auburn, Marcus E. Jones, a larger form, with 8 to 10 

 rays and about as many disk-flowers. 



# # Perennial, taller, with larger heads and some or most of the leaves opposite, occasionally 

 dentate: a manifest pappus to the disk-flowers, of plumose-lacerate or fimbriate palese. — Anuo-
