438 COMPOSITE. Ti-oximon. 



§ 2. Akenes ohlovg or fusifm^m, mostly acute or narrowed at base, and somexvhat 

 obliquely inserted by a small distinct callus {outermost occasionally pubescent), 

 the apex produced into a long {usually very long) and filiform or cajnllary 

 nerveless beak: pappus fine and soft, tardily deciduous. — Macrorhynchus. 

 {Macrorhynchus, Less., DC.) 



% Root ijerennial : ahenes either gradually or abruptly tapering into the slender and 



filiform beak. 



3. T. apargioid.es, Less. A span to a foot or so high from a long and often 

 large fusiform root, hirsute or glabrous : leaves variously pinnatifid or laciniate : 

 scapes slender, ascending : head middle-sized or rather small : akenes linear-fusiform, 

 acutely or the inner ones lightly ribbed, nearly equalling or a little shorten than the 

 beak. — Linna^a, vi. 501. Barkhansia Lessingii & Macrorhynchus Lessingii, Hook. 

 & Arn. Bot. Beechey, 145, 361. M. humilis, Benth. PI. Hartw. 320. M. Har- 

 fordii, Kellogg. 



Sandy or marsh)' grounds ; common along the coast, from Monterey to Oregon. Tliis species 

 is well described in the remark that it resembles Apargia autumnalis (i. e. Lcontodon autumnale), 

 and also, in its smaller form, Krirjia Vircjinica. Like these the foliage is very variable. Involu- 

 cre from 6 to 9 lines high ; the outer scales sometimes more foliaceous. Akenes 2 lines and the 

 beak 2 or 3 lines long. 



4. T. Nuttallii, Gray. About a foot high : leaves glabrous, varying from ob- 

 long-spatulate and laciniate-pinnatifid to linear and entire : scapes rather stout and 

 head rather large : scales of the involucre narrow : akenes fusiform-linear, slender, 

 hnely and closely ribbed, equalling the beak in length. — Proc. Am. Acad. ix. 216. 

 Stylojmppus elatus, Nutt. 1. c. Macrorhynchus elatus, Torr. & Gray, 1. c. 



Meadows, from the Yosemite Valley {Bolandcr) to Oregon, Nuttall, Hall, Kevins, &;c. Head 

 about an inch high. Akenes 4 lines and the beak 3 or 4 lines long. 



5. T. grandiflorum, Gray. Hirsutely pubescent or almost glabrous ; leaves 

 lanceolate or oblanceolate, mostly laciniate-pinnatifid, the lobes ascending or spread- 

 ing : scape one to 2| feet high : head large (an inch high) : outer scales of the in- 

 volucre commonly loose and foliaceous, varying from ovate to lanceolate : akenes 

 sliort-fusiform or oblong, abruptly tapering into the capillary beak of several times 

 its length. — Proc. Am. Acad. ix. 216. Stylop)apxms grandiflorus, Nutt. 1. c. 

 Macrorhynchus grandiflorus, Torr. & Gray, 1. c. 



Var. tenuifolium, Gray. ]\Iore slender, and heads someAvhat smaller : leaves 

 pinnately ]iarted into narrow linear divisions. — Stylopappus laciniatus, var. longi- 

 folius, Kutt. 1. c. 



Var. laciniatum, Gray. More slender and heads much smaller : outer scales of 

 the involucre not dilated : leaves lanceolate or linear and variously laciniate. — 

 Stylojxipipus laciniatus, Nutt. 1. c.1 



I\Ieadows and hillsides, from INIonterey Co. along the coast range to Oregon. The var. tcnui- 

 fnliiim has been collected only in Oregon and Washington Territory. The species is well marked 

 "when in fruit by the short and small akenes (only 2 lines long), with very long and capillary 

 beak, 6 or 8 lines long. 



% >.v Root perennial : akenes abruptly beaked from a truncate apex. 



6. T. retrorsum, Gray, 1. c. Almost woolly when young with soft loose hairs, 

 or glabrate : leaves runcinately and deeply pinnatifid, the linear-lanceolate lobes all 

 turned downwards, the apex usually prolonged and entire, all tipped Avith a callous 

 gland : scapes about a foot high : head large (1| inches long in fruit) but narrow: 

 outer scales of the involucre short and lanceolate, the inner long and linear : akenes 

 short-linear, closely 10-ribbed, their callous or slightly broadened summit very obtuse 

 or truncate at maturity ; the capillary beak very long. — Macrorhynchus refrorsus, 

 Benth. PI. Hartw. 320 ; Gray in Bot. Wilkes Exp. 373. M. angustfolius, Kellogg 

 in Proc. Calif Acad. v. 47, a small form of the species.
