 the suniiait : scalt-s of the pappus naked or }ninutely scabrous externally, varying' 

 from ovaLe-lancoolato to oblung-lunceolate, and tailoring gradually into a blenilor 

 longer awn. — Cdlain Jii(/etoi>u, (Iray in Pucif. II. Kep. iv. 113, t. 17. 0. Doiig-

 Akenus '2 or at niotst 2^ lines long, rather turbinate : pajjpus 3 to 5 lines long. 



9. M. Douglasii, Oray, 1. c. Between the last and the next : akenes more 

 slender, fusit'orui, tapering toward the summit almost as much as toward the base : 

 scales of the pappus silky-villous externally, of firmer texture, ovate-oblong and more 

 or less tapering into a rather stout long awn. — Calais DoiKjlasii, DC. Prodr. vii.

California, probably near Monterey, Douglas. As yet known only from his s^ieciinens. Akenes 

 3 to 3.^ lines long, in shape most like thos(! of the seetion Calocalais. Pappus including the awn 

 fully 5 lines long ; its st:alcs resembling those of the next s|iecies in texture, but narrower and 

 acute : the akene.s very dilfcrent from those of the next or of the preceding si)ceie8. Hut the 

 plant is too little known. 



4- +- Pappus-sades orbicular or vtrij broadly ovate, and obtuse or retuse at the apex, 

 abruptly awned : akenes thick; slightly or not at all constricted under the broad 

 apex. 



10. M. cyclocai'pha, Cray, 1. c. Like laigor forma of ^f. Biyehvii: awns of 

 the pappus slender, twice or thrice the length of the ample and (in the typical form) 

 mostly glabrous and smooth scales. — Calais cyclocarpha. Gray in Pacif. K. Pep. iv. 

 115, t. 18. 



Var. eriocarpha, Cray, 1. c. Awns of the pappus rather shorter, and its 

 scales consi)icuously silky-villous externally. — C. eriocarpha. Gray, Proc. Am. 

 Acad. vi. 552. 



Giussy plains and hillsides, Napa Valley (Bifjelow), and Humboldt Co. {Kellogg) ; the latter 

 showing a few long loose hairs on the back of the papi)us-scales, which suggest the union of tho 

 var. criocnrpha : this collected at Nipoma {Brewer) and on Monte Diablo, Bloomer. The larger 

 heads three (piarters of an inch high. Akenes 2\ to 3 lines long ; and the pai)pus-scales some- 

 times nearly 2 lines in length, sligiiliy erose-denticulate at the broad summit, more or less invo- 

 lute when dry. 



11. M. platycarpha, Gray, 1. c. Resembles the jireceding : awns of the pap- 

 pus only about one third of the length of the broail round scale : young akenes not 

 contracted under the smnmit. — Calais platycarpha, Gray, 1. c. 



San Luis liey, on clay hills, Ptirnj. Known only in a single specimen, without full-grown 

 akenes. Scales of the pajipus nearly smooth, almost 3 lines long and fully 2 lines broad. 



§ i. Pappus not plumose, of 5 or rarely more atoned chaffy scales : akenes long and 

 slender, fusi/orm, tapering gradually upivards into a narrow neck or even 

 beak : involucre cylindraceous or campanulate, of lanceolate scales, the few 

 exte)-ior ones unequal and less distinctly calyculate : stem very short, branching 

 and leafy at the base, and sending up simple scape-like peduncles : corollas 

 very short, apparently transiently expanded, at evening or morning (I). — 

 Calocalais, Cray. {Calais § Calocalais, DC.) 



* Scales of the papjms only 5, lanceolate or oblong, abruptly awned from a notch 

 caused by the early sj>litting of the apex of the scale : leaves linear, mostly narrow, 

 either laciniate-pnnnatifid or entire: root annual, slender. 



12. M. Lindleyi, Gray, 1. c. A span or two high : pappus rusty-brownish ; its 

 scales about the length of the beakless but somewhat contracted akene, scabrous- 

 puberulent externally, oblong-lanceolate, their midrib continued beyond the (at first 

 .shallow) notch into a rather stout scabrous awn of nearly its own length. — Calais 

 Lindleyi, DC, 1. c.
