134 COMPOSITE. Aplopappus. 



cent. — Proc. Am. Acad. xi. 74, & Bot. Calif, i. 613. — S. California, on hills, Los Angeles 

 to the Mexican border {Palmer, Nevin, Lijon, and mountains of San Bernardino Co. to the 

 desert on the Colorado Kiver, Parry, Lemmon, Parish, Primjie. Heads of the plant in the 

 interior districts very numerous in ample and rather naked panicles, at Los Angeles sparse 

 and racemosely disposed along the elongated and intricate branches. 



++ ++ Involucre larger, campanulate, 15-30-flowered, subtended by several loose outer bracts 

 having elongated-subulate lierbaceous tips : leaves longer. 



A. pinifolius, Gray. Shrub 2 to 5 feet high, rather stout, with rigid erect branches : 

 cauline leaves from very narrowly linear to filiform, an inch or more long, mucronate ; those 

 of the fascicles and branchlets much shorter : heads not very numerous in a contracted 

 panicle, or scattered : proper bracts of the involucre broadly lanceolate and with a greenish 

 keel or midrib ; loose outer ones normally subulate, shorter than the innermost, and passing 

 into the small leaves of the flower-bearing brauchlet, or in a vernal state (with solitary larger 

 heads) developed into an iuvolncriform rosette of acerose-filiform leaves : rays commonly 

 6 to 10, short: akenes almost glabrous. — Proc. Am. Acad. viii. 6.36, & Bot. Calif, i. 312, 

 there described from the abnormal vernal state, in which the large and many-flowered head, 

 terminating a very leafy branch, seems to consist of two or three confluent ones. In autumn 

 the normal paniculate and naked heads are developed. — S. California, from Los Angeles 

 Co. to the foot-hills of the San Bernardino, Bolunder, Parry, Nevin, Parislt, &c. 

 * * * Leaves from narrowly linear to lanceolate-spatulate, not rigid nor punctate, mostly plane, 

 seldom with axillary fascicles: low and suffruticose, not at all or very slightly balsamic or vis- 

 cidulous : at least the outer involucral bracts acute or acutely herbaceous-tipped: akenes pubes- 

 cent to glabrate. 



-)^ Glabrous throughout: leaves narrow. 



A. Bloom eri, Gray. A foot or two high, with erect and rigid usually virgate branches, some- 

 times lower, very leafy : leaves from narrowly spatnlate-linear to filiform-linear, an inch or 

 two long : heads showy, half to three-fourths inch high, in dwarf plants solitary terminating 

 fastigiate branches, commonly several and racemosely clustered, or more numerous and thyr- 

 soid-paniculate : involucre oblong ; its inner bracts oblong-lanceolate or linear, chai-taceous 

 with thin-scarious and erose-ciliate margins, some obtuse, some acute or tipped with a soft 

 cusp, most of the outer bearing a filiform foliaceous tip : rays 2 to 4, rarely solitary, oblong, 

 deep yellow, half-inch or less long : disk-flowers 8 to 20 : their style-appendages long and 

 much exserted, setaceous-subulate : akenes 3 or 4 lines long, sparsely pubescent. — Proc. Am. 

 Acad. vi. 541, vii. 354, viii. 356, & Bot. Calif, i. 313, with var. amjustatus, the narrower- 

 leaved form, passing freely into the broader, and to this belongs A. resinosus, Gray in 

 Wilkes Ex. Exp. xvii. 346, t. 10. Ericameria erecta, Klatt in Abh. Naturf. Gesel. Halle, 

 XV. 6, from the char. & habitat. — California and adjacent Nevada, along the Sierra Nevada 

 from Kern Co. northward to Washington Terr. ; first coll. by Picl-eriruj and Brackenridije, 

 next by Bloomer and Anderson. 



A. nanus, Eaton, a span to a foot high, in depressed tufts, fastigiately branched, disposed 

 to be Ijalsamic-glutinous : leaves from narrowly linear to narrowly spatulate (the largest less 

 than inch long) : heads solitary or fastigiate-clustered at summit of branchlets, 3 or 4 lines 

 high, narrow : bracts of the involucre lanceolate, acute or acuminate, pale, wholly destitute 

 of green tip or midrib, except one or two looser and subulate outermost : flowers all pale or 

 ochroleucous, or even " white " : rays small, 3 to 6 or in some heads wanting ; disk-flowers 

 8 to 12, with deeply 5-cleft corolla : style setaceous-subulate and hispid : akenes either pubes- 

 cent or glabrous. — Bot. King Exp. 150. A. resinosus, Gray, Bot. Calif. 313. Ericameria 

 nana & E. resinosa, Nutt. Trans. Am. Phil. Soc. 1. c. 318; Torr. & Gray, Fl. ii. 236.— 

 Eocky hills and cliffs, eastern borders of Washington Terr., and Oregon, adjacent Idaho, 

 and W. Nevada; first coll. by Nuttnll. Flowers said by Cusick and Brandecjee to be white; 

 by Nuttall, in his E. resinosa, ochroleucous. 



Var. cervinus. Leaves broader ; lower ones from oblanceolate to obovate-spatulate : 

 heads more scattered. — A. cervinus, Watson, Am. Nat. vii. 30; Rothrock in Wheeler Kep.

 •i— -i— Minutelj' viscidulous-pubescent. 



A. TVatsoni, Gray. A span or two high, like the broader-leaved variety of the foregoing, 

 but coarser and manifestly pubescent : leaves from lanceolate with narrowed base to obovate- 

 spatulate, thinnish : heads half-inch or less higli, loosely fastigiate-clustered : involucral
