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

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



■i— -i— Rays 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 palea', wliich are 

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

 or more high, very leafy. 



H. fioribuilda, Gray. Minutely g]andular-])ubesccnt 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 tuherculate-rugose, obscurely 

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

 ish palea; slujrter than the proper tube of the corolla. — Proc. Am. Acad. xi. 79, & Bot. Calif, 

 i. 016. — California, southern part of San Diego Co., Palmer, Cleveland. 



H. paniculata, Gray. More diffusely branched, below commonly hirsute, the liranchlets 

 aud heads viscid-glandular • cauline leaves laciuiatc-pinnatifld ; tliose of the branches entire 

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

 erect : heads sparsely ])aniculate, barely 3 liues 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 11 ; their well-formed akeues with a pappus of 

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

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

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

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

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



H. Kelloggii, Greene. Hirsute, sparsely so above, bearing sliort-pedicelled loosely panicu- 

 late heads : cauline leaves mostly ])innately-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 : raj'-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 ecpialling the tube of their corolla, com])osed of 

 lacerately truncate ])ale;c, which are mostly connate to near their summits. — Bull. Torr.

H. W^rightii, Gray. Hirsute below, I to 3 feet high, with widely-spreading branches, 

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

 heads : lower cauline leaves laciniate-pinuatifid ; tliose 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 paleas, their summit erose-laciniate. — Proc. Am. Acad. 

 xix. 17. — S. California, about San Beruardiuo, W. G. WrUjld, Parish, Parry. Found also 

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

 of fully their own length. 



H. fasciculata, Torr. & Gray. More or less hirsute or his])id 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 piuuately jjarted 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 glaudular-hispidu- 

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

 transver.sely rugose, apiculate with a small very short beak; disk-akenes chiefly sterile, with 

 conspicuous paj)pus of 8 or 10 narrowly oblong or linc^ar lacerate-tipj)ed palea;. — Fl. ii. 397;
