cent. Proc. Am. Acad. xi. "4, & Bot. Calif, i. 613. S. California, on hills, Los Angeles 

 to the Mexican border (Pulimr, Xn-in, LI/OH, and mountains of San Bernardino Co. to the 

 desert on the Colorado River, Parr;/, Lemmon, Parish, Primjle. Heads of the plant in the 

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

 and ramnosely disposed along the elongated and intricate branches. 

 H. .H. Involucre larger, campanulate, 15-30-flowercd, subtended by several loose outer bracts 



having elongated-subulate herbaceous tips: leaves longer. 



A. pinifolius, GIIAY. 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, mucrouate ; those 

 of the fascicles and brauchlets 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 branchlet, or in a vernal state (with solitary larger 

 heads) developed into an involucriform rosette of acerose-nliform leaves : rays commonly 

 6 to 10, short: akenes almost glabrous. Proc. Am. Acad. viii. 636, & Bot. Calif, i. 312, 

 there described from the abnormal venial 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, Bulunder, Purnj, Nerin, Pariah, &c. 



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

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

 cidulous: at least the outer involueral bracts acute or acutely herbaceous-tipped: akeues pubes- 

 cent to glabrate. 



H Glabrous throughout : leaves narrow. 



A. Bloomeri, GRAY. A foot or two high, with erect and rigid usually virgate branches, some- 

 times lower, very leafy : leaves frum narrowly spatulate-linear to filiform-linear, an iuch or 

 two long: beads showv, half to three-fourths iuch high, in dwarf plants solitary terminating 

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

 snid-pauiculate : involucre oblong ; its inner bracts oblong-lanceolate or linear, chartaceous 

 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 Hues long, sparsely pubescent. Proc. Am. 

 Acad. vi. 541, vii. 354, viii. 350, & Bot. Calif, i. 313, with var. uiiijtmtatus, the narrower-

A. nanus, K\n\. A span to a foot high, in depressed tufts, fastigiately branched, disposed 

 to be balsamic-glutinous : leaves from narrowly linear. to narrowlv spatulate (the largest less 

 than inch long) : beads 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, wilh <//>/!/ '>-</,// nini/lii : style setaceous-subulate and hispid : akenes either pubes-
