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

1. MADA"RIA. Ligules exserted and conspicuous: disk-Howers 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, will) mostly alternate leaves and small heads: pappus both to ray and 

 disk-flowers ! 



M. Yosemitana, PARRY. A span or more high r 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 glabrous : bracts of the involucre with short and narrow tips ; 

 of the receptacle -1 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 palea?. Aniso- 

 carpus, Nutt. Trans. Am. Phil. Soc. vii. 388. 



M. Nuttallil, GRAY. Stem slender, a foot or two high: leaves linear-lanceolate: heads 

 sparsely paniculate, 4 lines high, usually slender-peduncled : involucral bracts 8 to 12, with

 obovate-falcate, much compressed, with sides many-striate and nearly nerveless : pappus of 

 sterile disk-flowers of small oblong pale*. Proc. Am. Acad. 1. c. viii. 391, ix. 188, Bot.
