 ceiit : leaves some narrowly linear and entire, the otiiers palniately or pedately 3-5-parted 

 above into linear lobes: bracts of the broad involucre 10 to 12 : rays as many or fewer, with 

 oval ligules seldom surpassing the disk : pappus of about 4 slender awns and as many or

 diffuse, villous-tomentose when young, commonly glabrate : leaves linear or ligulate (the 

 larger 4 to 10 inches long), laciniate-pinuatifid and the linear segments sometimes again 

 cleft, or tlie upper occasionally entire; iuvolucral bi-acts and oblong exserted rays 10 to 13 : 

 pappus sometimes none, commonly of 2 or 3 stout cliaffy awns, and as many or twice as 

 many siiorter broad and trmicate laciniate-fimbriate palea;. — Dic/ucta idujinoMi, Nutt. Trans.

Var. tenera, Gray. Depauperate, on drier soil, 2 to G inches high: leaves linear, 

 entire, or some of the lowermost laciniate : rays oval or oblong, little or not at all exceeding 

 the disk : paleaj and awns each usually 2, the former very broad and quadrate, or splitting 

 into 2 or 3. — Proc. Am. Acad. xix. 22. Dichaia tenella, Nutt. 1. c ; Torr. & Gray, 1. c. — 

 With the ordinary form : also at Tulare Station, Parry. 



§ 0. Ptilomeris. Pappus wholly of awned or of muticous and commonly 

 erose palea?, or sometimes wanting : receptacle not muricate-roiighened, rather 

 scrobicnlate : involucral bracts in fruit c:u-iuate at centre outside, plicate-concave 

 within, and at length deciduous with the subtended akene, as in § Dichceta; heads 

 of the same : leaves all pinnately or lower ones bipinnately parted into linear 

 and attenuate divisions : not woolly, mostly somewhat glandular, diffuse. — Proc. 

 Am. Acad. xix. 23. Hymenoxys (Hook.), Torr. & Gray, Fl. ii. o80, not Cass.

* Rays 6 to 8, oblong, short-ex.serted : involucral bracts ovate-oval: receptacle either acutely or 

 obtusely conical, glabrous: heads small (barely 3 linos high): plants a span high, minutely 

 pubescent, obscurel^Mf at all glandular, with filiform-linear divisions to the leaves: the two 

 following perhaps forms of one species. 



B. affinis, Gray. Pappus of 8 or 10 oblong or lanceolate palccE with laciniate-setulose mar- 

 gins, fully ecjualling the corolla tube, some or most of them produced into an awn almost 

 equalling disk-corolla, or in the ray blunt and awnless. — Proc. Am. Acad. xix. 23. Ptilomeris

ill. # Raj's 10 to In, elongated-oblong, exserted: involucral bracts oblong-lanceolate: receptacle 

 acutely conical, minutely and sparsely pubescent : plants minutely glandular-pubescent, diffusely 

 branched, a span to near a foot high, perhaps all varieties of one, the difference being mainly in 

 the pappus. 



B. COronaria, Gray, 1. c. Pappus of 8 to 12 lanceolate or oblong denticulate palea;, all 

 tapering into awns, little shorter than disk-corollas, or some in the ray awnless : riiys nearly
