PLANTS OF UNDETERMINED STATUS 



ELEOCHARIS BELLA (Piper) Sven. (Cyperaaceae) This species is very similar to the more common E^ acicularis, and 

 many specimens identified as the latter may be the former. Further work on identifications is needed. 



ERIGERON BELLIDIASTRUM Nutt. (Asteraceae) Reported for Yellowstone County by Dorn (198^), but we have been unable 

 to locate any specimens to verify this report. 



ERIOGONUM CAESPITOSUM Nutt. (Polygonaceae) The identification of two collections at MONT ( Ryerson and Vogel 554. 

 W.E. Booth s.n. ) is uncertain. Dorn (1984) reports this species from southern Montana, but J. Reveal (pens. comm. ) 

 states that it does not occur in Montana. 



ERIOGONUM CHRYSOCEPHALUM Gray (Polygonaceae) Reported for southwestern and southcentral Montana by Dorn (1984). 

 Taxonomic problems are involved. 



ERIOGONUM UMBELLATUH var. AUREUM (in ed. ?) (Polygonaceae) This is currently an undescribed and unpublished taxon 

 reported to us by James Reveal. 



ELEOCHARIS FLAVESCENS (Poir.) Urban (Cyperaceae) Reported for Montana by Dorn (1984) and Hitchcock and Cronquist 

 (1973), but we have been unable to locate any specimens to verify these reports. 



ERIOPHORUM SCHEUCHZERI Hoppe (Cyperaceae) This species is reported for Montana by Hitchcock and Cronquist (1973) 

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



GEUM CANADENSE Jacq. (Rosaceae) More information on distribution and abundance is needed to determine the status of 

 this species in Montana. Reported for north-central and northeastern Montana by Dorn (1984). 



GEUM ROSSII (R.) Br. var. ROSSII (Rosaceae) Reported from the Mission Range in Lake County by Hitchcock and 

 Cronquist (1973). Further information on distribution and abundance is needed to determine the status of this 

 variety in Montana. 



GNAPHALIUM PURPUREUM L. (Asteraceae) There is one collection of this species from Missoula Co. in 1917 (Hawkins 

 s.n. MONT). It has not been collected in Montana in the past 70 years. Cronquist (1955) reports that this is a 

 weedy American species; thus, it may be adventive in Montana. 



GRIMDELIA NANA Nutt. (Asteraceae) There are collections and reports of this species from northwest Montana; 

 however, specimens are difficult to distinguish from the more common G^ squarrosa . Further information on the 

 taxonomy and distribution of this plant in Montana is needed. 



HALIHOLOeos VIRGATA (Nutt.) Schulz (Brassicaceae) This species has been recently collected in Liberty and Sheridan 

 counties, but additional information on distribution and abundance is needed to determine its status. 



HEHICARPHA DRUMMONDII Nees (Cyperaceae) Reported from Carbon County by Dorn (1984). A single collection by Booth 

 ( s.n. , 1941; MONT) was taken near Fromberg, but additional information on distribution and abundance is needed to 

 determine the current status in Montana. 



HIEROCHLOE ALPINA (Sw. ex UiUd.) R. & S. (Poaceae) Reported for northern Montana by Hitchcock and Cronquist 

 (1973), but we have been unable to locate any specimens to verify this report. 



HYMENOPAPPUS FILIFOLIUS Hook. var. IDAHOENSIS Turner (Asteraceae) The identification of many of our specimens is 

 uncertain. 



HYMENOPAPPUS FILIFOLIUS Hook. var. LUTEUS (Nutt.) Turner (Asteraceae) The identification of many of our specimens 

 is uncertain. 



LEPIDIUM NONTANUM Nutt. (Brassicaceae) In Montana, this species is known only from roadside habitats in Beaverhead 

 Co. Although native further south, this species may be adventive in Montana. 



LIGUSTKUM PORTERI Coult. & Rose (Apiaceae) Reported for Carbon Co., but we have been unable to locate vouchers. 



HUHLENBERGIA NINUTISSIHA (Steud.) Swallen (Poaceae) Reported for Gallatin County by Dorn (1984), based on a 

 collection by Booth ( s.n. . 1941; MONT). This specimen was taken from a roadside near Belgrade, where it may have 

 been adventive. 



HUHLENBERGIA MONTANA (Nutt.) Hitchc. (Poaceae) The location of a collection by Payne (collection number unknown; 

 MONT) is unknown. 



NAVARRETIA DIVARICATA (Terr.) Greene (Polemoniaceae) This plant is reported for Montana by Hitchcock and Cronquist 

 (1973) and Dorn (1984), but we have not seen any specimens to verify these reports. 



OENOTHERA ELATA H.B.K. ssp. HIRSUTISSINA Gray (Onagraceae) A specimen from Valley Co. appears to be this species, 

 but it would be greatly disjunct from the currently known range of the species. Determination of this specimen is 

 necessary. 



OENOTHERA PALLIDA Lindl. var. PALLIDA (Onagraceae) A recent taxonomic revision indicates that our specimens may be 

 composed of two taxa, 0^ pallida and 0^ latifolia (Rydb.) Munz. Further taxonomic clarification is needed.
