Var. Barclayi, Gray, Proc. Am. Acad. ix. 190, & Bot. Calif. 1. c. (excl. pi. Brewer), 

 from Monterey, Barclay, has more conspicuous laciniate pappus to disk-flowers. 



-)— -t— Kays 8 to 20, broadly cuneate or quadrate: disk-flowers more numerous, with well-formed 

 and often fertile ovary and a conspicuous pappus of coriuceous oblong obtuse palea?, which are 

 hirsute at summit and margins, and even on the back : stems erect, paniculately branched, 2 feet 

 or more high, very leafy. 



H. floribunda, Gray. Minutely glandular-pubescent and viscid, not hirsute : cauline leaves 

 all linear, small, entire : heads disposed to be racemose-paniculate on the branches : rays 

 about 20; their akenes in more than one series, somewhat tuberculate-rugose, obscure'lv 

 4-angled, with very short straight beak : disk-akenes numerous, with pappus of 5 to 8 broad- 

 ish paleas shorter than the proper tube of the corolla. — Proc. Am. Acad. xi. 79, & Bot. Calif. 

 i. 616. — California, southern part of San Diego Co., Palmer, Cleveland. 



H. paniculata, Grat. More diffusely branched, below commonly hirsute, the branchlets 

 and heads viscid-glandular • cauline leaves laciniate-pinnatifid ; those of the branches entire 

 or 2-3-dentate, linear, small; of the flowering branchlets mostly very small and bract-like, 

 erect : heads sparsely paniculate, barely 3 lines high : iuvolucral bracts minutely densely 

 glandular: rays about 8; their akenes coarsely rugose or pitted on the back: receptacular 

 bracts connate or distinct: disk-flowers about 11 ; their well-formed akenes with a pappus of 

 8 or 10 oblong paleae which exceed the proper tube of the corolla. — Proc. Am. Acad. xix. 

 17. — Santa Barbara Co. to San Diego Co., Brewer, Parish, Jared. Includes plant of coll.

-i — H — h — Kays 5 (rarely 3, 4, or 6), broadly cuneate or quadrate: disk-flowers not over 6, sur- 

 rounded by mostly 5 receptacular bracts, which are usually more or less connate ; their akenes 

 generally sterile, the paleas of their pappus not hirsute: stems paniculately branched, a foot or 

 two high, some taller : lower cauline leaves pinnatifid ; upper and rameal entire, small. 



H. Eelloggii, Greene. Hirsute, sparsely so above, bearing short-pedicelled loosely panicu- 

 late heads : cauline leaves mostly pinnately-parted or toothed : involucre quarter-inch high ; 

 the bracts hirsutely glandular on the back, broadly lanceolate : rays fully 3 liues long : 

 bracts of the receptacle rather broad, well united into a cup : ray-akenes tuberculate-rugose 

 (a line or more long), bearing a rather strongly lateral and slender curved (almost sigmoid) 

 beak : sterile disk-akenes with pappus about equalling the tube of their corolla, composed of 

 lacerately truncate paleae, which are mostly connate to near their summits. — Bull. Torr. 

 Club, x. 41. — Central California near Antioch (Kellogg), and along the San Joaquin Valley, 

 Greene. 



H. Wrightii, Gray. Hirsute below, 1 to 3 feet high, with widely-spreading branches, 

 when much branched decumbent ; the slender or filiform branchlets terminated by pedicellate 

 heads : lower cauline leaves laciniate-pinnatifid ; those of the branchlets mostly minute and 

 very viscid-glandular, as is the involucre ; its bracts ovate-lanceolate ; those of the receptacle 

 partly united : ray-akenes obscurely tuberculate-rugose, with short beak : sterile disk-akenes 

 with pappus of 8 or 9 oblong firm palese, their summit erose-laciniate. — Proc. Am. Acad. 

 xix. 17. — S. California, about San Bernardino, W. G. Wright, Parish, Parry. Found also 

 as a waif near San Francisco, Greene. Heads always scattered, and most of them on pedicels 

 of fully their own length. 



H. fasciculata, Torr. & Gray. More or less hirsute or hispid below, a span to 2 feet 

 high, commonly with rather rigid ascending glabrate or viscid-glandular branches, bearing 

 usually fasciculate-clustered sessile small heads : cauline leaves mostly pinnately parted or 

 laciniate; uppermost on the branches subulate-linear and rather crowded about the heads 

 or clusters : bracts of the involucre narrowly lanceolate, either glabrous or glandular-hispidu- 

 lous ; of the receptacle lightly united or nearly free : ray-akenes either smoothish or at length 

 transversely rugose, apiculate with a small very short beak ; disk-akenes chiefly sterile, with 

 conspicuous pappus of 8 or 10 narrowly oblong or linear lacerate-tipped palea?. — Fl. ii. 397;
