B. nudata, DC. Glabrous : stems slender, a foot or two high from a small caudex, strict 

 and simple up to the componnd-fastigiate and corymbose cyme of numerous heads : leaves 

 not punctate nor obviously viscid, spatulate to nearly filiform, uppermost small and bract- 

 like : heads barely 3 lines high, subclavate : bracts of the involucre about 3 in eacli rather 

 indistinct vertical ranii, oblong-linear, obtuse and firm-chartaceous, or at least outermost 

 with short greenish tips. Leaves in tlie original of the species spatulate-linear, or uppermost 

 narrower, lowest and radical commonly broader (sometimes half-iucli wide) and rounded- 

 obtuse. — Prodr. V. 329, & Mem. Comp. t. 5 B. nudata, var. spathulcF folia, Torr. & Gray, Fl.

 inconspicuous: style-apjiendages hardly exserted out of the o-lobed limb of the 

 corolla, subulate-oblong to short-filiform, shorter or not longer than the stigmatic 

 portion : akenes mostly short and turbinate, sericeous-pubescent : shruliby, be- 

 coming more or less balsamic-viscid, and with entire punctate leaves : corollas of 

 outermost flowers sometimes deformed. — § Aplodiscus, Enthamioideoe, mainh-,

* Stems simple below and fastigiately branched above, 3 to 12 feet high, bearing numerous heads

B. Cooperi, Gray. Apparently low, with leaves half-inch or less long, balsamic-viscid : 

 heads few in a cluster at the end of the branchlets, 6-8-flowered : bracts of involucre nar- 

 rowly oblong, chartaceous, pale to the apex : style-appendages ovate-subulate. — Proc. Am. 

 Acad. viii. 640, & Bot. Calif, i. 315. — S. E. California, on eastern slope of Providence

B. brachylepis, Gray. Shrub 4 to 6 feet high : leaves inch or half-inch long, balsamic- 

 viscid, conspic-uously resinous-punctate : heads loosely paniculate or solitary terminating 

 paniculate branchlets, 8-12-flowered, 4 or .5 lines higli : bracts of the campanulate involucre
