Baeria. COMPOSITE. 327 



B. Fremonti, GRAY, 1. c. Erect, slender, a span or two high, somewhat hirsute-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 : ravs 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 paleae, or rarely none. Dichceta Franontii, Torr. in PI. Fendl.

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



B. uliginosa, GRAY, I.e. 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. Dichicta nllijinosn, 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 : paleae and awns each usually 2, the former very broad and quadrate, or splitting 

 into 2 or 3. Proc. Am. Acad. xix. 22. Dtrluttu imclla, Nutt. 1. c j Torr. & Gray, I.e. 

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



3. PTILO.MERIS. Pappus wholly of awned or of muticous and commonly 

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

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

 within, and at length deciduous with the subtended akene, as in Dicliccta : 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. 380, not Cass.

* Rays 6 to 8, oblong, shovt-exsertecl : 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 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 paleae with laciuiate-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 cuncate paleae, 

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

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

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



* * Rays 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 paleae, all 

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

 half-inch long. Ptilomcns coronuria & P. ariftnta, Nutt. in Trans. Am. Phil. Soc. vii. 382.
