446 SUPPLEMENT. 



17. CARPHEPHORUS, Cass. The section § 2. Ktjhnioides, and the 

 species under it to be suppressed. Vide 163 1 , Bebbia, p. 453. 



24. PENTACH^TA, Nutt. 



P. aiirea, Ntjtt., p. 120. Add syn. : P. paleacea, Greene, Bull. Calif. Acad. i. 189. The "tri- 

 angular palea at base " of the pappus-bristles is evident in most specimens, from Nuttall's 

 onward. 



P. Lyoni. Hirsute, at least the margins of the plane linear or spatulate-linear leaves, 4 to 7 

 inches high, with the sparing ascending branches leafy up to the head or short peduncle : 

 involucre hirsute ; its bracts linear-lanceolate and of nearly equal length, green, with narrow 

 scarious margins: pappus-bristles 9 to 11 or commonly 12! — S. California, at San Pedro, 

 Los Angeles Co., and Catalina Island, W. S. Lyon. An anomalous species, evidently allied 

 to P. aurea, notwithstanding the involucre and the more numerous pappus-bristles, which 

 are repugnant to the generic name. 



27. CHRYSOPSIS, Nutt. 



C. graminifolia, Nutt., p. 121. A probable synonym is Erigeron Carolinianum, Walt. 

 Car! 205. 



C. gOSSypina, Nutt., p. 122. Here may belong Erigeron squamosum, Walt. 1. c. But 

 C. gossypina, Nees, PI. Neuwied Trav. 1 4, must be C. villosa. 



C. "Wrightii. Ammodia, near C. Breweri, p. 124. Pubescent with fine soft hairs: bracts 

 of the involucre all partly herbaceous, and the inner nearly equalling the flowers : corollas 

 with limb slightly hairy outside : stigmatic 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. — S. California, on the San Bernardino Mountains, 

 at 11,500 feet, W. C. Wright. 



30. APLOFAPPUS, Cass. 



A. Orciittii, Gray, Proc. Am. Acad. xx. 297, an extraJimital species of Lower California,, 

 connects the rayless A. sguarrosus, p. 125, with the radiate Pyrrocomoid species. And the 

 following connects these with the Arnicella group. 



A. Howellii. Before A. uniflorus, p. 128. A span or two in height, branching from base 

 into ascending few-leaved monocephalous stems, sericeous-torn entose, glabrate in age : leaves 

 all narrowly lanceolate and acute, entire, or rarely a denticulatiou : head and involucre nearly 

 of A. uniflorus, the bracts of the latter of equal length and rather obtuse : style-appendage9 

 long and slender in the manner of A. carthamoides : akenes also elongated (oblong-linear) 

 but pubescent, nearly as long as the rigid pappus. — On Stein's Mountain, S. E. Oregon, 

 June, 1885, Howell, Cusick. 



A. spintllosus, DC, p. 130. Add syn. . Sideranihus spimtlosus, "Fraser ex Steud."; Nees, 

 PI. Neuwied Trav. 15 (515). 

 A. junceus, Greene, Bull. Acad. Calif, i. 190, S. W. border of California, is one of those 



forms intermediate between A. gracilis and the polymorphous A. spinulosus. 



34. LESSfNG-IA, Cham. P. 161, add : Pappus not rarely of awns rather 

 than capillary bristles (especially in depauperate heads), then correspondingly 

 fewer and sometimes irregularly concreted at base in pairs or phalanges. The 

 species are polymorphous and not readily limited. 



L. ramulosa, Gray, p. 162. Tack-shaped glands abound on the margins of the leaves 

 whenever these are rigid : pappus-bristles inclined to unite at base into five phalanges. 



Var. adenophora. Tack-shaped glands conspicuous, even on involucral bracts: 

 heads only about 8-flowered : pappus of few bristles in 5 paleaeeous-aristiform phalanges, or
