Head few - manydiowered, heterogamous, with 1 to 20 pistillate rays, or rarely 

 the rays entirely wanting ; the diskdlowers hermaphrodite, either fertile or sterile. 

 Involucre a single series of herbaceous scales, which are carinate and conduplicate, 

 enclosing as many akenes, their free tips erect or involute. Receptacle flat or 

 convex, with somewhat herbaceous chad between the ray- and diskdlowers, usually 

 more or less united into a cup, otherwise naked or lindnillate hirsute. Kays more 

 or less cuneiform, 3dobed at summit. Akenes linear-oblong or clavate-oblong, 

 incurved or nearly straight, laterally compressed, minutely many-striate, glabrous 

 (those of the ray with Hat sides), wholly destitute of pappus, or in one section a 

 chall'y-plumose pappus to mostly sterile diskdlowers. — Glandular and more or less 

 viscid heavy-scented annuals ; with linear or lanceolate entire or slightly toothed 

 leaves, at least the upper alternate ; and oitlier peduncled corymbose, or pauicled, or 

 clustered heads of yellow llowers, opening at evening, early morning, or in cloudy

* Disk-flowers with a pappus composed of fimbriate or jdumose-lacerate and slender 

 chaffy scales. {Anisocarpiis, Wutt.) 



1. M. Nuttallii, Gray. Hirsute: stem slender, a foot or two high: all the 

 lower leaves opposite, denticulate or occasionally beset with slender salient teeth : 

 heads rather .small and paniculate, tenuinating slender glandular peduncles : scales 

 of the involucre with short inconspicuous tip.s, rather large for the size of the head : 

 fertile akenes obovated'alcate, the many-striate sides nerveless ; those of the disk all 

 abortive: pappus very much shorter than the corolla. — Gray, Proc. Am. Acad. viii.
