 3-nerved, with prominent upturned beak : disk-pappus minute and squamellate or nearly 

 wanting. Prodr. v. 692 ; Torr. & Gray, Fl. ii. 398 ; Gray, Bot. Calif, i. 362. //. multi'caulis,

Var. Barclay!, GRAY, Proc. Am. A cad. ix. 190, & Bot. Calif. 1. c. (excl. pi. Brewer), 

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



-i -i Hays 8 to 20, broadly cuneate or quadrate: disk-flowers more numerous, with well-formed 

 and often fertile ovary and a conspicuous pappus of coriaceous oblong obtuse paleaj, 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 iu more than one series, somewhat tuberculate-rugose, obscurely 

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

 ish palea 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, GRAY. More diffusely branched, below commonly hirsute, the branchlets 

 and heads viscid-glandular cauliue leaves laciniate-pinuatifid ; those of the branches entire 

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

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

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

 bracts connate or distinct : disk-flowers about 1 1 ; their well-formed akenes with a pappus of 

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

-f -i -i Rays 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 paleae of their pappus not hirsute: stems paniculately branched, a foot or 

 two high, some taller: lower cauline leaves pinnatilid; upper and rame;il entire, small. 



H. Kelloggii, GREENE. Hirsute, sparsely so above, bearing short-pedieelled loosely panicu- 

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

 the bracts hirsutely glandular on the back, broadly lanceolate : rays fully 3 lines 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 paleaj, which are mostly connate to near their summits. Bull. Torr. 

 Club, x. 41. Central California near Autioch (Kelloyy), and along the San Joaquiu Valley,

H. "Wriglltii, 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-pinuatifid ; 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 palete, 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 giabrate or viscid-glandular branches, bearing 

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

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

 or clusters : bracts of the involucre narrowly lanceolate, either glabrous or gland ular-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 paleae. Fl. ii. 397 ;
