Nomenclatural conspectus of California Sedges

Dean Wm. Taylor

The purpose of this conspectus is to present nomenclatural information about California sedges and to identify UC holdings of type materials. Many North American sedge species were established wholly or in part on material collected by the Geologic Survey of California by William H. Brewer and Henry N. Bolander. The Geological Survey specimens not only served to found the University of California Herbarium, but provided much type material of western plants to Asa Gray and Sereno Watson. Prior to this review, many of the early Carex types in the University Herbarium had not been not identified as type material.

In the era when many sedges were first described, the type concept was not yet fixed. Many species were described from syntypes. Mackenzie, in reviewing protologues of species authored by either Olney or Liberty Hyde Bailey, designated lectotypes using the phrase "is taken as the type." Some workers might consider Mackenzie's choices to be mechanical and thus not in conformance to Article 9A.2, but it should be noted that most recent treatments of Carex (Reznicek and Ball (1980, Standley 1985 etc.) accept Mackenzie's choices, as do I (after all, how can mere botanists counter the choice of a New York lawyer!). I know of no case with respect to California sedges where the mechanical method of selection has resulted in a conflict between the protologue and the historical application of the name.

For ease of reference, numbers used in this conspectus are the Section or Species numbers as they appear in Mackenzie (1935).  The sectional nomenclature used by Mackenzie is now quite antiquated.  Egorova's monograph [The sedges (Carex L.) 1999) of Russia and adjacent states.  Mo. Bot. Garden Press. 1999] provides needed typification of many supraspecific taxa used in this list (antiquated names are in RED] .  In a few instances, the protologue was not seen by me (indicated by Protologue Not Seen).  Distributional Notes that correct or supplement distribution maps based on the Jepson Manual are indicated.


A. Subgenus Psyllophora (Degl.) Peterm.
Deutsch. Fl. 602. 1849
( = Primocarex Kuk., Das Pflanzenreich 4, 20 (Heft 38). 1909.)
Spike single, typically androgynous.  About 25 Sections comprising about 75 species of largely extratropical, typically alpine or arctic, distribution.  LECTOTYPE: Carex pulcharis L.

2. Sect. Capituligerae Kuk.  Bot. Jahrb. 27:495. 1899.
( Capitatae Christ. Bull. Soc. Bot. Belgium 24(2):20. 1885.)
SYNOPSIS: 4 species, C. capitata is arctic-alpine of northern Eurasia and North America, extending southward on high mountains to northern Mexico (populations requiring study as subspecifically distinct?); C. rhuiensis Kurtz is from Argentina, the other species, C. oreophila C.A. Mey., is in the mountains of western Asia; C. antarctogena Roivainen of Tierra de Fuego is sometimes separated from C. arctogena. TYPE: Carex capitata L
3. Carex capitata L. ssp. arctogena (H. Smith) Boecher
Arctic. Alp. Res. 3, 2:144. 1971. |Jepson Manual Distribution |Specimens|
TYPE: based on C. arctogena H. Smith
NOTE: a special status plant in Oregon.
Carex arctogena H. Smith
Acta Phytogeogr. Suec. 13:193. 1940.
TYPE: Swedish Lapland, H. Smith s.n. (S, DAO)
3. Sect. Inflatae Kuk.
Das Pflanzenreich 4, 20 (Heft 38):96. 1909.
SYNOPSIS: two to perhaps four dry site alpine taxa of western North America, o in the Sierra Nevada
5. Carex breweri F. Boott var. breweri
Illus. Carex. p. 142 & pl. 455. 1867. | Jepson Manual Distribution |Specimens|
TYPE: California, Siskiyou Co., Mt. Shasta W.H. Brewer 1422 in 1863 (isotype GH27152). No type material at UC.  The relationships of Carex breweri var. paddoensis (Suksd.) Cronq. (a rare plant in Idaho, isotype NY11263) and Carex engelmanii L.H. Bailey warrant study.

5a. Carex subnigricans Stacey
Leaf. Western Bot. 2:167. 1939. |Jepson Manual Distribution |Specimens|
TYPE: California, Tuolumne Co., Mt. Dana, J.T. Howell 14519 (holotype CAS259816, isotypes, GH27450, US1765699, UC618535). Paratypes cited in the protologue include F.W. Peirson 10828, 11400, 12280 (CAS, RSA), McCraken s.n. July 25, 1936 (CAS), C. Sharsmith 102 (CAS), 2356 (CAS, isoparatype UC714264), D.D. Keck 4657, 4914 (CAS, DAO) J.T. Howell 14136, 14154 (CAS); H.S. Yates 6012 (VTM, not at UC). The UC duplicates of the paratypes were not cited in the protologue, and are therefore isoparatypes (paratypes are not listed in the online CAS type catalog).
NOTE: a special status plant in Oregon.

Carex rachillis B. Maguire
Brittonia 5:199. 1941
TYPE: Utah, Summit County, Gilbert Peak, B. Maguire et al. 14668

25. Sect. Callistachys (Heuffel) Mack.

Krecz in southern Europe, C. micropoda of boreal Europe and Asia, and Alaska, and Carex cephalotes F. Muell. is found in New Zealand.
9. Carex nigricans C.A. Mey. |Jepson Manual Distribution |Specimens|
Mem. Acad. Imp. Sci. St.-Petersburg. Ser. 6, Sci. Math. 1:211 & pl. 7. 1831.
TYPE: from Unalaska, Alaska, Ludolf Adelbert von Chamisso (isotype GH27346). Two specimens in the NY catalog that are listed as types (NY11234 & NY11224) are likely not such.  Egorova (1999) lists the type as Unalaschka, Mertens (Holotype LE, isotypes LE), casting into doubt the citation of a Chamisso specimen as the type.
22. Sect. Polytrichoideae Tuck.
Enum. Caric. 8. 1843.
SYNOPSIS: Monotypic, Sphagnum bogs in North America (very rare in California, known from NCo bogs).
198. Carex leptalea Wahl. - | Jepson Manual Distribution |Specimens|
Kongl. Vetensk, Acad. Nya Handl. 24:139. 1803.
TYPE: "in America borealis, secundum herbarium Cl. Torneri".
NOTE: A special status plant in California (CNPS List 2, vouchered from Del Norte, Humboldt, Marin [extirpated] and Trinity counties), Idaho, and Oregon.
24. Sect. Filifoliae Tuck.
Enum. Caric. 8. 1843.
SYNOPSIS: 6 dry ground, montane species of western North America, with C. arsenii Kuk. in the Michoacan subalpine;

TYPE: Th. Nuttall, on the dry plains and gravely hills of the Missouri, in 1813.
DISTRIBUTIONAL NOTE: the UC-JEPS specimen records are not yet updated.  An additional CA station is: Shasta Co., Burney Spring, DWT 9839.

207. Carex exserta Mack.
Bull. Torrey Bot. Club. 42: 620. 1915. | Jepson Manual Distribution |Specimens|
TYPE: based on C. filifolia var. erostrata Kuk.

Carex filifolia var. erostrata Kuk. in Engler
Das Pflanzenreich 4, 20 (Heft 38):86. 1909.
LECTOTYPE: Ezra Brainerd 111. Lectotype designated by Mackenzie (Erythea 8:52. 1922); in North Am. Flora 18:180. 1931, this specimen is cited as Brainerd, July 11, 1897 (lectotype GH27229, isolectotype UC864).
SYNTYPES: Hall et Chandler 616 (UC865), M.E. Jones 2908 (UC825102)
28. Sect. Scripinae Tuck.
Enum. Caric. 8. 1843.
SYNOPSIS: 7 species in a polymorphic, circumboreal complex, often of calcareous dry soils: in North America, one into Eurasia.  Starr et al. (AJB 86:563-577. 1999) found this Section was misplaced within Subg. Psyllophora [Primocarex].  Note that Mackenzie, although he did not treat subgenera, placed the Scripinae next to Sect. Digitatae, which is Subg. Carex.  Following Mackenzie's placement has the utility of making Subg. Psyllophora [Primocarex] monophylletic.
240. Carex pseudoscirpoidea Rydb.
Mem. N.Y. Bot. Gard. 1:78. 1900. | Jepson Manual Distribution |Specimens|
LECTOTYPE: Wyoming, Spanish Peak, Yellowstone Park, Rydberg 3064 (NY11290)  Lectotype designated by Mackenzie N.Amer. Flora 18:209. 1935, and accepted by Dunlop (Novon 7:355-356, 1997).
SYNTYPE: Rydberg 3412 (NY214536)
NOTE: a special status plant in California (CNPS List 2, vouchered from Alpine, Inyo and Mono counties)
Carex scirpoidea Michx. var. pseudoscirpoidea (Rydb.) Cronq.
Univ. Wash. Publ. Biol. Sci. 17(1):325. 1969.

Carex scirpoidea Michx. ssp. pseudoscirpoidea (Rydb.) D.A. Dunlop
Novon 7:355. 1997.

242. Carex scabriscula Mack.
Bull. Torrey Bot. Club 35:268. 1908.
TYPE: Oregon, Cascade Mountains, Cusick 2849 June 30, 1902 (holotype NY11317, distributed as C. feta, isotypes DS490735, CU, ORE17812, OSC153663, POM, US528631, WS).
241. Carex gigas (Holm) Mack.
Bull. Torrey Bot. Club. 35:268. 1908. | Jepson Manual Distribution |Specimens
TYPE: based on C. scirpoidea var. gigas Holm
NOTE: a special status plant in Oregon.

Carex scirpoidea var. gigas Holm
Am. Jour. Sci. Series 4, 18:20 & f. 8. 1904.
TYPE: Dunlop (1997) states that Holm failed to designate a type, and that Mackenzie's reference to a type from Siskiyou County, California, C.G. Pringle s.n., August 18, 1881 (NY11321) did not constitute a lectotypification.  She, however, did not select an alternate lectotype.  The disjunct distribution and ecological differences may indeed warrant recognition of C. gigas as a valid taxon.

31. Sect. Triquetrae Carey ex Olney
Proc. Am. Acad. 7:395. 1868.
SYNOPSIS: 5 dry ground species in temperate North America.

 TYPE: "found in Arctic regions"  NY11336 is a possible type
Carex invisa L.H. Bailey
Proc. Amer. Acad. 22:82. 1886.
TYPE: "Summit Camp, California, Kellogg, the type growing ‘in exceedingly tough and
matted clumps".  Holotype presumably at BH.
TYPIFICATION: Bailey’s exact wording of the protologue suggests by implication that he took the Kellogg collection as the holotype, and the other specimens cited were representative material (paratypes).  Throughout Bailey’s Carex synopsis, he did not make specific reference to herbaria in which type material was seen.  He did note "if I have seen and examined critical or historic specimens, the collector’s name is printed in Italics", as is the case in this instance. PARATYPES: Ebbett’s Pass, W.H.Brewer 2084 (UC993) and 2076 (UC994); Big Trees, Hillebrand; Lassen’s Peak above snow, W.H.Brewer 2186 (UC992) ["a globular spiked form"]; Carson Pass, W.H. Brewer 2126 (UC999); Selkirk Range, British Columbia, Macoun."  The following specimen listed as a syntype: California, Mariposa County, Yosemite Valley, H.N. Bolander 6198 (US30161), but this number at other herbaria also serves as type material of C. whitneyi and C. paucicostata, and was not mentioned in the protologue.

Carex jepsonii Mackenzie ined (not Carex jepsonii mackenzii as in the NY database?)
an ined. name attributed to NY11184 as a type in their database, W.L. Jepson 4577, 31 July 1911.  The specimen label is in Jepson's handwriting, and the specimen appears (from my inspection of the image) to be Carex spectabilis Dewey.

61.  Sect.  Phacocystis Durmot.  Fl. Belg. 146.
(Sect. Acutae (Fries) H. Christ, Fl. Scan. 191. 1835)
SYNOPSIS: a group of ca. 80 species of swamps of the Holoarctic; probably best developed in Asia.  Mackenzie recognized 42 species in North America.  Several species in southern South America and Australasia.  Barely reaching North Africa.  Mackenzie notes "the fundamental distinguishing characters are found in the underground parts; these are unfortunately usually not gathered by collectors (Egorova 1999 also laments incomplete specimens).  The scales and spikes vary much in size and shape in the same species, and distinctions based upon them need an unusual amount of verification by a study of abundant material".   Partially fertile hybrids complicate identification.  TYPE: Carex cespitosa L. (Europe).  Egorova (1999) places this Section in Subg. Kreczetoviczia Egor, along with Sect. Temnemis (below)and 6 other sections [Abditispicae Wheeler, Graciles (Tuck. ex  Kuk.) Ohwi;  Forficulae Franch. ex Raymond; Praelongae (Kuk.) Nelmes and Tuminescens Y.I. Chang & Y.L. Yang)]

The CAS type catalogue lists an isotype in their collection (DS54663), but this specimen in a syntype.  UC1049 is a sheet of Bolander 6198 that is Carex lenticularis var. impressa, and is therefore not a syntype of C. whitneyi, but is rather a paratype of C. paucicostata.
Carex flaccifolia Mack.
Erythea 8:92. 1922.
TYPE: 'southwestern California', George B. Grant, 1 May 1902 (US468192).  Howell (Leaf. W. Bot. 8: 221-224. 1958) concluded that the specimen was actually collected in Yosemite Valley.

(Sect. Sylvaticae F. Boott in Tuck. Enum. Caric. 12. 1843. of Mackenzie 1935)
SYNOPSIS: a polyphylletic group of meadow and wetland species, with about 40 species.  Work by Waterway & Olmstead (unpub.) suggests our species formerly placed in Sect. Sylvaticae and a core group of Sect. Gracillimae Carey form a monophylletic group related to Sect. Hymenochlaneae Drej. ex L.H. Bailey.  There are perhaps two undescribed California taxa in this section (cf. L. Janeway 1992.  Cyperaceae of Butte County, Cont. Herb. Chico State Univ.), both in the Sierra Nevada, requiring study.
