Inflorescence of C. argyrantha (L) and C.foenea (R). 
argyrantha or C. siccata from Oregon. Anumber of Oregon speci¬ 
mens formerly identified as C. siccata are discussed under that 
species. One collection originally labeled C. siccata was anno¬ 
tated to C. foenea in 1947, but is actually C. praegracilis (GH). 
These three taxa are readily separated. Carex siccata is rhi- 
zomatous, while the others are cespitose. Carex argyrantha has 
perigynia with an abrupt transition to a narrow beak, while C. 
foenea has no distinct beak, but a broad gradually tapered apex 
Carex foenea Willd. var. tuberculata F. J. Herm. was de¬ 
scribed by Hermann (1968) from five collections, in Washing¬ 
ton, Colorado, New Mexico, and Alberta. No mention was made 
of Oregon specimens, and Oregon was not discussed in the ar¬ 
ticle. When Hermann (1970) wrote his Rocky Mountain Carex 
treatment, he implied the habitat was "dry (occasionally moist) 
to sterile, open habitats (but also occurring in lodgepole pine, 
spruce, and aspen stands) at lower to middle elevations (but up 
to 13,000 ft. in Colorado)." Two years after the original de¬ 
scription of the taxon, Hermann (1970) revised his range state¬ 
ment to: "Alberta to Washington and Oregon, and southeast¬ 
ward to Colorado." Carex foenea var. tuberculata is synonymous 
with C. siccata, (Cronquist et al. 1977; A A Reznicek, pers. 
comm., Kartesz 1999), but we have not located a specimen to 
support Hermann's (1970) range statement. If found, the voucher 
would represent the first Oregon collection of C. siccata. 
Carex globosa Boott is endemic to western California and 
adjacent Mexico. Howell (1903) reported the species from: "Cali¬ 
fornia to Washington." Modem surveys found the plant as far 
north along the coast as Del Norte County, California (Zika et 
al. 1998). No specimens are yet known from Oregon or Wash¬ 
ington. We assume Howell confused the plant with more wide¬ 
spread species like C. rossii. Kuykendall et al. (1997) reviewed 
the situation, noting that most Oregon collections annotated to 
C. globosa were eventually recognized as a new species, C. 
serpenticola (ORE, OSC). The two are differentiated by large 
perigynia 3.9-5.1 mm long, with stipes 1.2-2.3 mm long in C. 
globosa ; vs. small perigynia 3.1-3.6 mm long, with stipes 0.4- 
0.8 mm long in C. serpenticola. 
Carex haydenii Dewey (sect. Acutae) is a wetland sedge 
from the eastern United States, found west to South Dakota 
and Missouri. Peck (1961) listed "C. haydenii 01ney...wet ground 
at high altitudes in the Wallowa Mountains." The source of this 
remarkable typographical error is quite a different alpine sedge, 
(not mentioned by Peck 1961), but with a similar name: Carex 
haydeniana Olney (sect. Ovales). Carex haydeniana grows in the 
Wallowa Mountains of Oregon and across the mountains of the 
western United States. We never found a collection of C. haydenii 
from Oregon. The inflorescences of the two differ; in C. 
haydeniana the spikes are in a head-like cluster, while C. 
haydeniana has an elongate array of spikes. 
Carex helleri Mack, is endemic to California and Nevada, 
where it is found near or above treeline. Carex Working Group 
(1993) tentatively placed C. helleri on a list of rare Oregon sedges, 
based on specimens from Steens Mountain, Harney Co. (OSC). 
However we later reidentified all collections as C. atrata var. 
erecta, and the recent flora of Steens Mountain does not include 
C. helleri (Mansfield 1995). Carex atrata var. erecta has loosely 
clustered spikes, and the lowest spike is often well separated 
from the terminal spikes; in contrast C. helleri has all spikes 
closely aggregated at the tip of the stem. 
Carex lanuginosa Michx. is mentioned here because it was 
the name used for many years for the common sedge we now 
call C. pellita Muhl. ex Willd. Carex lanuginosa no longer ap¬ 
pears on our checklist of Oregon Carex, because of nomencla- 
tural difficulties. Botanists probing the names and type collec¬ 
tions found that C. lanuginosa actually is synonymous with C. 
lasiocarpa var. americana (Gleason and Cronquist 1991). The 
latter is a rare plant in Oregon, and difficult to distinguish from 
C. pellita. The only reliable characters appear to be vegetative. 
The flattened leaves and lower inflorescence bracts of C. pellita 
are considerably wider than the inrolled leaves and bracts of C. 
lasiocarpa var. americana. (See range maps on page 22.)
