COMPOSITE. 447 



some of these reduced to a rigid awn. — L. adenophora, Greene, Bull. Calif. Acad. i. 190. — 

 Colusa Co., California, Mrs. Lat/ne-Curran. 



L. leptoclada, Gkav, p. 162. Pappus of fewer and more rigid bristles in the reduced forms, 

 such as the 



Var. microcephala, Gray, the most attenuate form, with only 5-flowered or even 

 3-flowered small heads. — Troc. Am. Acad. vii. 351, & Bot. Calif, i. 308, with var. tenuis. 

 L. nemaclada, Greene, 1. c. 191. — Not uncommon. 



L. nana, Gray, var. caulescens, p. 163. Add syn. : L. Parryi, Greene, 1. c. Almost ex- 

 actly the typical plant (which also ticcurs in the same region), except that, in addition to the 

 subradical heads, some elevated 3-4-cephalous shoots have developed. 



48. Aster, p. 172, &c. The following omitted mimes to be added in 

 their places, chietly as synonyms. 



A. ixtybAceus, Kunth & Bouchc, Adn. Ind. Sem. Hort. Berol. 184.5, & Ann, Sci. Nat. 

 ser. 3, V. 3.58, according to an original sjjecimeu, is ^4. Tartaricus, L. f., wrongly taken for 

 North American. 



A. SALSUGINOSUS, Less. in Linn. vi. 124 (not Richards.), is A. Sibiriciis, L., fide Herder. 



A. GRAVEOLENS, Nutt. Traus. Am. Phil. Soc. ser. 2, vii. 294, is a syn. of A. oUongifoUus, 

 Nutt., on p. 178. 



A. PUBESCENS, Nees, Syn. Ast. 16 {A. heterop/ii/Uus, var. Nees, Ast. 55), is a form of A. sagitti- 

 folius, Willd., p. 182. 



A. pinif6lius, Nees, Syn. Ast. 29 (referred to ^4. Tradcscanti in Nees, Ast. 103), seems to 

 be A. polijphi/llus, Willd , p. 184. 



A. ANGlJsTUS, Nees, Syn. Ast. 26 (referred, along with A. rigididtis, Syn. Ast. 29, to A. belli- 

 dijiorus in Nees, Ast. 97, seems to be a cultivated form of A. paniculatus, Lam., p. 187. 



A. EMiNENS, Nees, Ast. 87, is a mixture. The leading form is either A. junceus, Ait. (cited 

 by Nees as a synonym), or A. paniculatus, to which some of the varieties seem to belong; the 

 var. Iccvigatus is our A. Novi-Belgii, var. heriijatus (to which his synonym points) ; other forms 

 are more obscure. 



A. LUxURiAxs (Spreng. Syst. iii. 538), Nees, Ast. 538, is a broad-leaved form of A. Novi- 

 Bclgii. 



A. umbellAtus, Mill., should have the syn. supplied : Dosllingeria umhellata, Nees, Ast. 178, 

 a broad-leaved form. 



A. virgAtus, Nees, Syn. Ast. 27 (not Ell.), is a form of A. Novi-Belgii, L., p. 189. 



The above determinations from Nees were derived from a set of cultivated Asters supplied 

 by Nees to Hohenacker (either directly or indirectly), thence to Dr. Klatt, who obligingly gave 

 them to the author. 



A. HAydeni, Porter in Ilayden, Geol. Rep. 1871 (published 1872), 485, is a syn. of A. pul- 

 chellus, Eaton, p. 201. 



49. ERiG-ERON, L. On p. 214, after K Bloomeri, add: — 



E. nudatus, Gray. Like E. Bloomeri, but quite glabrous and smooth : leaves thickish, 

 narrowly sj)atulate-linear, obtuse, much shorter than the simple (span high) monocephalous 

 scape : involucre of thickish and green lanceolate bracts somewhat in two series : akenes 

 obovate-ol)long, sparsely pubescent: pappus whitish, simple. — Proc. Am. Acad. xx. 297. — 

 Dry hillsides, Waldo, S. W. Oregon, Howell. 



E. glaUCUS, Ker, p. 208. Here probably belongs E. sqiiarrosits, Lindl. Bot. Reg. xxvii. 

 misc. 44. No specimen has been found in tiie herbarium of Lindley. 



E. piimilus, Nutt., p. 210. Add syn. : E. sulcatus, Nees, PI. Neuwicd Trav. 13, according 

 to the chiiracter. 



B. Chrysopsidis, Gray, p. 210. Rays vary from yellow to cream-color and even white, 

 according to Suksdorf.
