Baeria. COMPOSITE. 327 



B. Frem6nti, Gray, 1. c. Erect, slender, a span or two high, somewhat hirsnte-pubes- 

 cent : leaves some narrowly linear and entire, the others palmately 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 

 more numerous narrow small paleaj, or rarely none. — Dichceta Fremontii, Torr. in PI. Fendl. 

 102. Burrielia (Dichceta) Fremontii, Benth. PL Hartw. 317. — Lower valley of the Sacra- 

 mento to San Francisco Bay ; first coll. by Fremont. 



B. ujiginosa, Gray, 1. c. A span to a foot or more high, at length loosely branched and 

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

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

 cleft, or the upper occasionally entire; involucral bracts and oblong exserted rays 10 to 13 : 

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

 many shorter broad and truncate laciniate-fimbriate paleae. — Dichceta uliginosa, Nutt. Trans. 

 Am. Phil. Soc. 1. c. 383; Torr. & Gray, Fl. ii. 380. — Wet ground or in shallow water, San 

 Francisco Bay to Santa Barbara ; first coll. by Coulter. 



Var. tenera, Gray. Depauperate, on drier soil, 2 to 6 inches high : leaves linear, 

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

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

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

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



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

 erose paleae, or sometimes wanting: receptacle not muricate-roughened, rather 

 scrobiculate : involucral bracts in fruit carinate at centre outside, plicate-concave 

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

 of the same : leaves all pinhately or lower ones bipirinately parted into linear 

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

 Am. Acad. xix. 23. Hymenoxys (Hook.), Torr. & Gray, Fl. ii. 380, not Cass.

 Baeria § Ptilomeris, Gray, Proc. Am. Acad. xix. 21, 23. 



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

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

 pubescent, obscurely if at all glandular, with Aliform-linear divisions to the leaves : the two 

 following perhaps forms of one species. 



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

 gins, fully equalling 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 

 affinis, Nutt. PI. Gamb. 174. — S. California, from Los Angeles to San Bernardino, Gambel, 

 Nevin, Parish. 



B. tenella, Gray, 1. c. Pappus of 6 to 10 short and firm quadrate or broadly cuneate palea;, 

 with the truncate muticous summit denticulate or nearly entire, not surpassing the tube of 

 the corolla. — Ptilomeris tenella, Nutt. PI. Gamb. 173. Actinolepis tenella, Gray, Bot. Calif, 

 i. 378, mainly. — Los Angeles, California, Gambel, Parry. 



# # Eays 10 to 15, 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 pales, all 

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

 half-inch long. — Ptilomeris coronaria & P. aristata, Nutt. in Trans. Am. Phil. Soc. vii. 382.

 common in cultivation, especially in France.
