PLANTS OF UNDETERMINED STATUS 



AGOSERIS AURANTIACA (Hook.) Greene var. PURPUREA (Gray) Cronq. (Asteraceae) The identity of collections at MONT is 

 uncertain; several of them may be Agoseris lackschewitzi i . These collections need to be verified before the status 

 of this variety can be determined. 



AMARANTHUS ULIFtKNICUS (Moq.) Wats. (Anaranthaceae) <nown from a single 90 year-old collection from Gallatin 

 County. Additional information on distribution and abundance is needed to determine the current status in Montana. 



ANTENNARIA PULCHERRIMA (Hook.) Greene (Asteraceae) This species is very similar to A^ anaphaloides . and it is not 

 clear how to unambiguously separate the two. Further information on this group is required to determine the status 

 of Montana collections. 



ARTEMISIA LONGILOBA (Osterh.) Beetle (Asteraceae) Reported for Beaverhead, Madison, and Deer Lodge cos. by Morris 

 et al. (1976); however, we have been unable to locate any specimens to verify this report. 



ARTEMISIA TILESII Ledeb. var. UNALASKENSIS Bess. (Asteraceae) Cronquist (1955) reports this species for western 

 Montana; however, it is difficult to distinguish from A^ ludoviciana var. lati loba . More information on the 

 taxonomy and distribution of this plant in Montana is needed. 



ASTER SIMPLEX Uilld. var. RAHOSISSIMUS (T. & G.) Cronq. (Asteraceae) Reported for Montana by Great Plains Flora 

 Association (1977); however, we have been unable to locate any specimens. 



ASTRAGALUS MISER Dougl. var. CRISPATUS (Jones) Cronq. (Fabaceae) Reported for Beaverhead County by Barneby (1964), 

 and known from two collections from Madison County ( Hitchcock and Muhlick 12532 . Hitchcock 15825 . both at WTU). 

 Additional information on distribution and abundance is needed to determine the current status in Montana. 



BULBOSTYLIS CAPILLARIS (L.) Clarke (Cyperaceae) Reported for Carbon County by Dorn (1984). A collection by Booth 

 ( s.n. . 1941; MONT) was taken near Fromberg, on a "sandy bench in a valley." This species is weedy in the eastern 

 U.S., and may be adventive in Montana (J. Rumely, pers. comm.). 



CALAMAGROSTIS KOELERIOIDES Vasey (Poaceae) Collected once in Montana by Booth (1942; GNP Herbarium), from a "sandy 

 roadside" near Lake McDonald, where it may have been adventive. Also reported from the Little Rocky Mountains by 

 Ramsden (UESTECH, Helena), but we have been unable to locate any specimens to verify this report. 



CALAMAGROSTIS SCOPULORUM Jones (Poaceae) Described as "doubtfully in Montana as reported" by Hitchcock and 

 Cronquist (1973). The identity of a collection from Ravalli County ( P.F. Stickney 2207 . MONT) is uncertain. 



CAMISSONIA TAHACETIFOLIA (T. & G.) Raven This species is reported by Hitchcock and Cronquist (1973) (as Oenothera 

 tanacetifol ia T. & G.) for Montana, but we have been unable to locate any specimens to verify this report. 



CAREX AENEA Fern. (Cyperaceae) Reported by Standley (1921), Hitchccock and Cronquist (1973), and Dorn (1984) for 

 Montana, but we have been unable to locate any specimens to verify these reports. 



UREX EBENEA Rydb. (Cyperaceae) The identity of two collections at MONTU (Ravalli ( K.H. Lackschewitz & T. Fageraas 

 827 ) and Glacier ( L.H. Harvey 6664 ) counties) is disputed. Both specimens were identified as C. EBENEA by F. J. 

 Hermann; M. Colson confirmed the plant from Ravalli County, but was uncertain about the Glacier County collection. 

 A. Cronquist does not recognize the occurrence of the species in Montana, and referred both collections to C. 

 haydeniana Olney. Clarification of these taxonomic problems is needed. 



CAREX EBURNEA Boott (Cyperaceae) This inconspicuous species is known from three widely separated areas in Montana. 

 It may be more common than these records indicate. More information on the distribution of this species is needed. 



CAREX JONESII Bailey (Cyperaceae) Reported for Montana by Hermann (1970). The identity of a collection by K. 

 Lackschewitz (MONTU?) is apparently disputed. 



CAREX MICROGLOCHIN Uahl. (Cyperaceae) This plant is reported for western Montana by Hermann (1970); however, we 

 have been unable to locate specimens to verify this report. 



CAREX STRAMINIFORMIS Bailey (Cyperaceae) Reported for Montana by Hermann (1970), Hitchcock and Cronquist (1973), 

 and Dorn (1984), but we have not been able to locate any specimens to verify these reports. 



CAREX TINCTA (Fern.) Fern. (Cyperaceae) Known only from a roadside collection near Yellow Bay, Flathead Lake, in 

 Lake County (Hermann 1970), where it has not been relocated; the status of this species in Montana is currently 

 unknown. 



CLAYTONIA LANCEOLATA Pursh var. FLAVA Nels. (Portulacaceae). Recent taxonomic studies indicate that this plant may 

 be more common in Montana than previously thought. 



CORDYLANTHUS CAPITATUS Mutt. (Scrophulariaceae) Reported for southwest Montana by Dorn (1984); however, we have 

 been unable to locate specimens to verify this report. 



CRYPTANTHA KUMILIS (Gray) Pays. (Boraginaceae) Reported for Beaverhead and Park cos. by Dorn (1984), but we have 

 been unable to locate vouchers. 



CYPERUS ERYTHRORHIZOS Muhl. (Cyperaceae) Reported for Missoula Co. by Dorn (1984), but we have been unable to 

 locate vouchers.
