COULTER AND ROSE—NORTH AMERICAN UMBELLIFERAE, 69 
The Cahto specimens cited above, and in the Botany of California referred by 
Watson to W. ambigua, are clearly to be associated with W. bolanderi. They are 
less puberulent than the type specimens of that species, and the fruit is considerably 
smaller (14 to 16 mm. long). 
12. Washingtonia ambigua ((rray) C. & R. 
Glycosma ambiquum Gray, Proce. Am. Acad. 8: 386. 1872. 
Osmorhiza ambigua C. & R. Rey. N. Am. Umbell. 119. 1888. 
Glabrous, or hairy near the nodes; leaves 2 to 3-ternate; leaflets 
broadly ovate, thin, 2.5 to 6.5 cm. long, acute, serrate, and more 
incised than in W. veerdentalis; umbel 4 to 8-rayed, naked; fruiting 
rays 3 to 6 cm. long, widely spreading; pedicels*2 to 10 mm. long: 
fruit 12 to 18 mm. long, acutish at hase, glabrous, and distinctly beaked: 
stylopodium slightly conical, style 1 mm. long; seed face slightly 
concave. 
Type locality, ** foot of Cascade Mountains, Oregon;” collected by 
fall, no. 217, in ATL; type in Herb. Gray. 
Mountains of Oregon and Washington. 
Specimens examined: 
OrEGOoN: Type specimen as cited under type locality; Oakland, Howell 178, April, 
1881; Wolf Creek, Josephine County, fowell 124, May 23, 1884. 
WASHINGTON: Faleon Valley, Suksdorf 382, July, L880; Mount Paddo (Adams), 
Suksdorf 1197, August 10, 1882; same station, Henderson, in 1882; same sta- 
tion, Suksdorf 1196, September 18, 1884; same station, altitude 1,800 to 2,100 
meters, Suksdors, June-August, 1885; Goat Mountains, altitude 1,350 meters, 
Allen 256, August 8-September 19, 1896. 
In examining the type specimen we find that the character ‘“‘ ribs toward the base 
more or less setose’’ is based upon a single detached fruit, which proves to belong to 
W. purpurea, All the other fruits on the type sheet are completely glabrous, 
Specimens collected by (dowel! at Grant’s Pass, Josephine County, Oreg. (no. 123, 
May 25and June 21,1884), 
and at Oakland, Oreg. 
(no. 178, April, 1881), 
seem to belong to W. 
ambigua, but they are 
quite pubescent.
