30 THE GENUS CAREX IN CALIFORNIA 



of W. Boott arose from two plants being distributed under Bolander 1568, as explained under Carex 

 Cusickii, and is really intended to refer to part of Bolander's collection rather than to W. Boott's 

 description. Boott's pi. 402 is from the Bigelow collection, and it, part of Bolander 1568 and the Brewer 

 and Kellogg & Harford material, represent the same plant. Palmer 389 as represented at the Gray 

 Herbarium is Carex subfusca W. Boott, although it is cited by W. Boott in Bot. Cal. 2: 232 as "C. f&tida 

 All." (C. vernacula Bailey). It is to be noted in this connection that Palmer 389 is the first number 

 cited by Bailey under Carex J "estiva var. stricta Bailey, Mem. Torr. Club 1:51. Under the circumstances 

 I take Bigelow's specimens as the type of the species. 



15. C. vicaria Bailey. Culms 3-6 dm. high, sharply triangular (exceeding 

 the leaves), strongly roughened on angles above; leaves with blades 3-4.5 mm. wide, 

 the sheaths tight, not conspicuously septate dorsally, thin hyaline and more or less 

 cross-rugulose ventrally, short-prolonged and convex at mouth; head 1.5-3 cm. long, 

 about 12 mm. wide, decompound, the clusters closely aggregated, or the lower 

 slightly separate, the individual spikes hardly recognizable, the perigynia in each 

 few, spreading at maturity; bracts inconspicuous except 1 or 2 lower ones; scales 

 ovate, acute to cuspidate, shorter than perigynia, reddish-brown tinged with green 

 midvein; perigynia 3-3.5 mm. long, 1.5 mm. wide, plano-convex, smooth, ovate 

 from a rounded base, substipitate, reddish tinged with green margin, few nerved 

 dorsally, nerveless ventrally, the body sparingly serrulate above, contracted into 

 the serrulate bidentate beak Y% length of body. 



Type Locality: Oregon (E. Hall). 



Marshes and swales, Washington to northern California. 



Locs.: Round Valley, Mendocino Co., Chestnut 108, 285; "California," Kellogg & Harford 1068.

 Bailey, Proc. Am. Acad. 22: 137 (1886). C. vulpinoidea Michx. var. vicaria Kiik., in Engler, Pflzr.

Carex vicaria Bailey is based on "Carex glomerata" Boeckl. in part, Linnaa 39: 59 and W. 

 Boott in Bot. Cal. 2: 232 (1880), and on "C. Brongniartii" Bailey, and the range is given "Oregon 

 and California," but no specimens are cited. Under Bailey's description of Carex Brongniartii, reference 

 is made to C. hypoxanthus Steud. and " C. glomerata authors not Thunb." and specimens are cited: 

 "Arizona; California, Kellogg & Harford 1068; wet meadows, Mendocino City, Bolander 4808; Oak- 

 land Slough, Bolander 6204; Oregon, Hall; Chili." Disregarding C. hypoxanthus Steud. and the Arizona 

 and Chili plants, as having been eliminated by Prof. Bailey, I am taking the Oregon plant collected 

 by Hall as the type of Carex vicaria. It is indirectly the first specimen cited and best answers the 

 rather general description given. The California specimens cited, except Kellogg & Harford 1068, seem 

 to me better referable to Carex densa Bailey. 



16. C. Dudleyi Mackenzie n. sp. Culms 3-6 dm. high, roughened on the 

 angles and sharply triangular beneath the head, exceeding leaves ; leaves with blades 

 4-7 mm. wide, flat, little roughened above, the sheaths tight, inconspicuously septate 

 dorsally, white hyaline and scarcely if at all cross-rugulose ventrally, short-pro- 

 longed and convex at mouth; head 2-3.5 cm. long, 9-12 mm. wide, decompound, the 

 spikes all very closely aggregated and hardly recognizable, the perigynia in each 

 few, spreading at maturity; bracts setaceous, at least the lower conspicuous; scales 

 ovate-lanceolate, mostly shorter than perigynia, yellowish-green, strongly cuspidate 

 or awned; perigynia 2.5-3 mm. long, 1.25-1.5 mm. wide, plano-convex, smooth, 

 narrowly ovate from a rounded base, substipitate, brownish-yellow with green 

 margin, few nerved dorsally, obscurely nerved ventrally, the body not serrulate, 

 contracted into the serrulate bidentulate beak of its own length. 



Type Locality: Tassajara Hot Spgs., Monterey Co., California (Elmer 2132). 

 Coast Ranges from Monterey Co. to Lake Co. Apparently local.

Named for the late Prof. W. R. Dudley, who had left notes with the type specimen in the 

 herbarium of Stanford University, showing that he recognized this as an undescribed species. Prof. 

 Dudley's large collections of Carex in California have very materially extended our knowledge of the 

 genus, and it is highly fitting that his labors and studies should be remembered.
