ADDITIONS. 



24. PENTACH^TA, p. 120, after P. aurea, add: 



P. L^oni. Hirsute, at least the margins of the plane liuear or spatulate-linear leaves, 4 to 7 

 inches liigh, with the sparing ascending branches leafy up to the head or sliort peduncle : 

 involucre liirsute ; its bracts liuear-lanceolate and of nearly equal length, green, witli narrow 

 Gcarious margins: pappus-bristles 9 to II or commonly 12! — San Pedro, Los ^Vngeles Co., 

 California, in clayey soil near Palos Verdes Jlountain, II'. .?. Liioii. An anomalous species, 

 evidently allied to P. aurea, notwithstanding the involucre and the more numerous pappus- 

 bristles so repugnant to the generic name. 



27. CHBYSOPSIS, § Ammodia, p. 124, add- 



C. ^^riglltii. Pubescent with fine soft hairs : bracts of the involucre all partly herbaceous, 

 and the inner nearly ci|ualling the flowers: corollas with limb slightly hairy outside : stig- 

 matic portion of the style-branches not much longer than broad, several times shorter than 

 the subulate-linear appendage : outer pappus scanty and obscure; inner extremely copious : 

 otherwise like C. Brewcri. — !?. California, on the ISun Bernardino Jlountains, at 11,500 feet, 

 Tl'. C. Wright. 



82. FRANSERIA, p. 2.31, after F. deltoidea, add: 



F. COrdifolia. Cinereous-puberulent, woody at base, branching above into a narrow and 

 loose panicle : leaves all long-petioled, cordate, obscurely 3-5-lobed, erenately serrate, an 

 inch or two long, thin : fertile involucres granulose-puberulent, the few subulate spines 

 rather shorter than the small body. — Arizona, in the mountains near Tucson, Pringle, Par- 

 ish. (Adj. Mcx., Pringle.) 



I'S?'. CROCKERIA, (h-eene, Nov. Gen. ined., next to Eatonella, p. 72, 

 323. (Dedicated by the (liseo\erer to Cliarles Crocker, Esq., of San Francisco, 

 one of the most liberal and enlightened promoters of botanical investigation m 

 C.alifornia and adjacent regions.) — Habit, involucre, flowers, and receptacle essen- 

 tially of Lasthenia § Hologymne. Akenes oval-obovate, very flat, the plane sides 

 nerveless, o-lubrous ; margins witli a distinct filiform nerve, and ^-ery densely 

 ciliate with short and pyriform or clavate ratlier rigid more or less glandular 

 hairs ; apex truncate. Pappus none. 



C. chrysantha, Greene, in Bull. Calif. Acad. ined. A span or two high from a slender 

 annual root, nearly glabrous, not at all woolly : leaves all opposite, linear, entire : heads a 

 quarter-inch hit;h: involucre nearly hemispherical, shorter than the disk; the 12 to 14 ovate 

 bracts cnpulate^connate to the middle : ray- and numerous disk-flowers golden yellow, and 

 quite like those of Lasthenia glahrata. To refer the plant to that genus seems impractica-
