and broader in Canbyi) ; fruit narrow to elliptical and with 

 wings not wider than body, mostly 2-3 lines long-, back more 

 convex, but wings thin, ribs prominent. This includes C. am- 

 higua (Nutt. Jour. Phil. Acad. 7 27 (1834) as Eulophus), 

 C. leptocarpa (Nutt. T. & G. Fl. 1 626 (1840) as Peucedanum 

 triternalum var.), C. bicolor (Watson Bot. King 129(1871) 

 as Peucedanum), C. orogenioides (Leibergia orogenioides, C. 

 & R.), C. circumdata (Watson Proc. A. Acad. 22 474 (1887) 

 as Peucedanum), C. Cous (Watson Proc. Am. Acad. 21 453 

 (1886) as Peucedanum), C. Watsoni (C. & R. Bot. Gaz. 13 209 

 (1888) as Peucedanum). All these have yellow flowers. The 

 white flowered forms are C. Canbyi (C. & R. Bot. Gaz. 13 78 



(1888) as Peucedanum), C. Hendersoni (C. & R. Bot. Gaz. 13 

 210 (1888) as Peucedanum), C. Piperi C. & R. Umb. 211 (1900) 

 as Lomatium), C. farinosa (Hooker Lond. Jour. Bot. 6 235

 14 293 (1879) as Peucedanum), C. Gormani (Howell Fl. 252 

 (1898) as Peucedanum). Plants of the Middle Temperate 

 Life Zone. 



The sixth section of Cogswellia is Campicola. This is 

 characterized by large and globose tubers at the ends of long 

 and erect roots or fusiform tubers nearer the surface; acau- 

 lescent or nearly so; leaves minutely pubescent, broad, pin- 

 nately or subtemateV dissected into rather coarse segments 

 which are inclined to be oblong or narrower, but not linear; 

 petioles thick, mostly flattened and short and rachis flattened, 

 leaves appearing as if glaucous ; fruit elliptical to oblong, in- 

 clined to be ovate, wings rarely as wide as body ; flowers white 

 or turning purplish. This includes C. Nevadensis (Watson 

 Free. Am. Acad. 11 143 (1876) as Peucedanum) and its varieties 

 cupulata (Tones Cont. 8 29 (1898) as Peucedanum), var. Par- 

 ishii (C. & R. Bot. Gaz. 13 209 (1888) as Peucedanum), and 

 var. pseudorientalis, C. Lemmoni (C. & R. Bot. Gaz. 14 277 



(1889) as Peucedanum) probably. All these have large and 

 deep-seated globose tubers rarely collected, most specimens 

 have only the elongated fleshy root above the tuber. The 

 other species with large oblong or fusiform tubers are C. ori- 

 entalis (C. & R. Umb. 220 (1900) as Lomatium), C. macro- 

 carpa (Nutt. T. & G. Fl. 1 627 (1840) as Peucedanum), C el- 

 Uptica (T. & G. Pac. R. R. Rep. 2 2 121 (1855) as Peucedanum 

 nudicaule var.) if this be a good species. This group grows 

 on the plains and table lands in the Lower and Middle Tern-
