454 SUPPLEMENT. 



ger often laciniate and petioled ; upper small and linear, or reduced to subulate minute 

 scales: flowers golden yellow, sweet-scented (somewhat as in those of Acacia Farnesiana). 

 Carphephores junceus, Beuth. & p. 113. B. utriplicifolia (Carphephorus atriplicifolius, Gray, 

 1. c.) of Lower California is probably the same, and var. aspera, Greene, 1. c., is a commo'n 

 hispidulous state. Rocky places, in canons, &c. in the arid regions of Arizona and S. E. 

 California (Lower Calif., first coll. by Hinds). Evidently an outlying representative of the 

 subtribe Liabece. 



192. SENECIO, Tourn. 



S. aureus, Var. Balsamitae, p. 391. Add syn. : S. ceratopkyllus, Nees, PI. Neuwied 

 Trav. 12. 



S. Neo-Mexicanus, GRAY, p. 392. S. Austins, Greene, Bull. Calif. Acad. i. 93, is 

 probably a form of this, from the northeastern borders of California, in Modoc Co., J)/?-s. 

 Austin. 



S. Lyoni. (Next after 5. eremopliilus, p. 393.) Obscurely stiff rutescent, and somewhat 

 succulent, early glabrate except the persistent dense tufts of wool in the axils : leaves once 

 or twice prinnately parted into linear obtuse segments and lobes, glabrous above, minutely 

 woolly-pubescent beneath : peduncle bearing a few pedicellate heads (these 4 to 6 lines 

 high and radiate): pedicels and involucre sparingly subulate-bracteolate. Island of San 

 Clemeute, off S. California, on cliffs by the sea, Nevin & Lyon, April, 1885. 



S. Calif ornicus, DC. Growing in sand along the sea-shore (San Diego and southward) it 

 becomes succulent and dwarf, when it is S. amnmpltilus, Greene, Bull. Calif. Acad. i. 193. 



At the end of the genus, p. 394, add : 

 * * * * Indigenous winter-annual : heads with few and minute ray-flowers, or none. 



S. Mohavensis. Glabrous, branching from the base, leafy up to the loose corymbiform 

 panicle: leaves soft and thickish, ovate or oblong, sinuate-dentate or sparingly incised, cau- 

 linewith auriculate or cordate-clasping base: heads slender-pednncled, 4 lines high: involucre 

 narrow-campanulate, 18-20-flowered; calyculate bracts few and inconspicuous: ray-flowers 

 when present mostly difformed and biligulate, not surpassing the disk: akeues canesceut. 

 S. E. California in the Mohave region, near the Colorado, Lemmon. (Also within the bor- 

 ders of Sonora, Mex., Pr ingle.) 



213. STEPHANOMERIA, Nutt. 



S- COronaria, Greene, Bull. Calif. Acad. i. 194, Santa Lucia Mountains, Brandegee, by the 

 character seems too like S. exirjua, Nutt , p. 414. 



219. MICR6SEBIS, SCORZONELLA. At end, p. 418, add: - 



M. Howellii, GRAY. A foot or more high from a fusiform root, slender, bearing solitary 

 or 2 or 3 heads: leaves (only 2 or 3 lines wide) elongated-linear and attenuate, some bearing 

 a few attenuate refracted lobes ; involucre half-inch high, narrow, 1 5-20-flowered ; its bracts 

 all acuminate ; inner oblong-lanceolate and all nearly equal; outer much shorter and mostly 

 ovate: akenes 3 lines long, narrower at base : pappus of 8 or 10 conspicuous and firm lance- 

 olate palese, which nearly equal the length of the akene and bear a denticulate-scabrous awn 

 of hardly greater length ! Proc. Am. Acad. xx. 300, where by some mistake the pappus 

 is quite wrongly described. Waldo, S. \V. Oregon, June, 1884, Ilowell. Ambiguous be- 

 tween the sections Scorzonella and Calais, with pappus-palere of the latter, except in number, 

 but perennial or biennial from a fusiform root, and the habit of a slender M. leptosepala. 



223. MALAC6THBIX, DC. 



M. Coiilteri, GRAY, p. 421. Anthesis vespertine or matutinal, the heads closed at 



midday. 

 M. insularis, GREENE. Intermediate between Mcdacolepis and Malacothrix subsection 



Malacomeris, annual, glabrous, a foot or two high : leaves oblong-lanceolate, laciniate-pinna-
