PLANTS OF UNDETERMINED STATUS 



OXYTROPIS CAMPESTRIS (L.) DC. var. COLUMBIANA (St. John) Barneby (Fabaceae) Rupert Barneby (personal 

 communication) believes that this taxon should be considered synonymous with the more common 0^ campestris var. 

 graci I is . Further taxonomic work is required to determine the correct status for this plant. 



PHYSALIS HETEROPHYLLA Nees (Solanaceae) This species is reported for Powder River County by Great Plains Flora 

 Association (1977), but we have not located any specimens. 



PHYSALIS PUMILA Nutt. [= P^ hispida (Waterf.) Cronq.] (Solanaceae) Reported for Fergus Co. by Dorn (198A), but we 

 have been unable to locate specimens to verify this report. Fergus Co. is way outside the range of P^ pumi la given 

 by Great Plains Flora Association (1977); thus, if the report is correct, this species may be adventive in Montana. 



PRIHULA ALCALINA Cholewa & Henderson (Primulaceae) A white-flowered primrose collected near Monida ( Rose 471 

 MONTU) has been determined to be this species; however, repeated searches of the area have located only populations 

 of the closely related and more common P^ incana . It is uncertain whether P^ alcalina is or ever was in Montana. 



SAXIFRAGA OREGANA Howell var. OREGANA (Saxif ragaceae) All Montana specimens appear to be intermediate between this 

 variety and the more common var. montanensis (Small) Hitchc. 



SELAGINELLA DENSA Rytlj. var STANDLEYI (Haxon) Tryon (Selaginel laceae) More information is needed on the 

 distribution of this species in Montana. 



SENECIO PAUCIFLORUS Pursh (Asteraceae) Reported for Granite Co. by Dorn (1984), but specimens from MONTU are on 

 loan. 



SENECIO HYPERBOREALIS Greerai. (Asteraceae) This species has been collected in Glacier Co. (Barkley 1978); however, 

 many authorities consider it to be synonymous with the more common S^ resedifol ius . Further information on the 

 ditribution and taxonomy of this taxon is needed. 



SOLIDAGO SPARSIFLORA Gray (Asteraceae) Reported for Carter and Wibaux counties by Dorn (1984). A specimen at MONT 

 (69723, collector unknown) was taken in Stillwater County, but additional information on distribution and abundance 

 is needed to determine the current status in Montana. 



SOLIDAGO SPATHULATA DC. var. NANA (Gray) Cronq. (Asteraceae) The identification of specimens at MONTU is 

 uncertain. 



SPARGANIUM ANDROCLADUM (Engelm.) Horong (Sparganiaceae) This eastern species is reported for Gallatin Co. by Dorn 

 (1984) and may be adventive in our area. 



SPOROBOLUS VAGINIFLORUS (Torrey ex Gray) Wood (Poaceae) Reported for Big Horn County by Dorn (1984), based on a 

 collection by Booth ( s.n. . 1941; MONT). This specimen was taken along a roadside, where it may have been adventive. 



STIPA LEMHONII (Vasey) Scribner (Poaceae) This species is reported for Montana by Hitchcock and Cronquist (1973) 

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



STIPA LETTERMANNII Vasey (Poaceae) Reported for Gallatin County by Dorn (1984), and southern Montana by Hitchcock 

 and Cronquist (1973). A collection at MONTU ( Peterson and Evanko 101390 . 1950) was taken in Madison County, and a 

 recent collection ( Collins 732 . 1983; RM) was taken in Big Horn County. The identifications of several specimens at 

 MONT, from Gallatin and Carbon counties, need to be verified (J. Rumely, pers. comm.). 



STIPA THURBERIANA Piper (Poaceae) A single collection ( Booth s.n. . 1943; MONT) was taken in Park County, but 

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



TOUNSENDIA LEPTOTES (Gray) Osterh. (Asteraceae) Reported for Madison County by Dorn (1984), but we have been unable 

 to locate any specimens to verify this report. 



TOUNSENDIA NUTTALLII Dorn (Asteraceae) Some Montana collections may be referable to this recently described 

 species. Further taxonomic work is needed. 



TRADESCANTIA BRACTEATA Small (Commel inaceae) Reported for Montana by the Great Plains Flora Association (1986) and 



for Custer Co. by Dorn (1984). Ronald McGregor (pers. comm.) believes that Montana specimens from Custer and Carter 



cos. are best referred to T^ occidental is . Further information on the taxonomy and distribution of this species in 

 Montana is needed. 



TRISETUM ORTHOCHAETUM Hitchc. (Poaceae) This taxon appears to be a sterile interspecific hybrid between T^ 

 canescens Buckl. and '\_^ wo I f i i Vasey. Known originally only from the type locality at Lolo Hot Springs in Missoula 

 County, it was rediscovered in the adjacent Granite Creek drainage in 1986. Studies of seed viability and 

 morphology support the theory of hybrid origin. 



VACCINIUM OVALIFOLIUH Smith (Ericaceae) Reported for Montana by Hitchcock and Cronquist (1973), but we have been 

 unable to locate any specimens to verify this report. 



VERBENA BIPINNATIFIDA Nutt. (= Glandularia bipinnat i f ida (Nutt.) Nutt.) (Verbenaceae) Reported for northeastern 

 Montana by Dorn (1984), but we have been unable to locate any specimens to verify this report.
