II. METHODS
The Mill Creek Timber Sale area was surveyed on 14-15 and 19-22 June 1989, and 10-14, 17-18 and 21 July 1989. Surveys of the Tie Creek Timber Sale were conducted on 26-28 June 1989 and 19-20 July 1989. A late-season survey of the East Boulder Mine Site was conducted on 8-9 August 1989, as a follow-up to earlier surveys of the site by other parties. Although the primary purpose of the surveys was to determine the occurrence or absence of plant species included on the sensitive plant list of Region 1 (Northern Region) of the U.S. Forest Service, species inventories of each area were prepared during the surveys as part of the working method. Maps of each survey area were provided to the author by the Gallatin National Forest, and formed the basis of a working strategy. Individual sale units and building sites were located and surveyed, and all vascular plant species observed were recorded. Special attention was given to drainages, sites with unusual substrates, and any other habitats where it was thought that uncommon species might occur.
Identification of collections was made following Dorn (1984), Hitchcock and Cronquist (1973), Hitchcock et al. (1969), Hitchcock and Chase (1950) and Hermann (1970) . A complete list of the vascular plant species observed during the surveys, and the study area(s) in which they were found, is presented in Part IV of Section One (pp. 4-23) .
III. CONCLUSIONS
Sites of proposed timber harvest and mining activity on the Gallatin National Forest were the focus of sensitive plant surveys during the 1989 field season. An inventory of plant species was made for each of the three areas of proposed use. These inventories did not reveal the presence of any plant taxa included on the list of sensitive plant species for Region 1 (Northern Region) of the U.S. Forest Service. This is not to say that no designated sensitive species occur within the surveyed areas. Although intensive, the surveys should be regarded as incomplete for several reasons. The surveys were conducted in June and July. Species in bloom either before or after this could have been missed. While inventories of habitat types and sale units were extensive, total physical coverage of each sale unit of the proposed timber sales was not possible. This leaves open the question of whether or not a sensitive species occurrence may have been overlooked.
Two plant species currently included on the Montana Natural Heritage Program list of plant species of special concern (Shelly 1989) were found during the surveys in the Mill Creek drainage: Carex multicostata and Erigeron formosissimus. Both of these species are also listed as "Rare" by Lesica et al. (1984). Additionally, Carex multicostata is included on the U.S. Forest Service Region 1 Watch List (U.S. Department of Agriculture 1988). Appendix A of Section One (pp. 24-34) contains reports for these species.

2. COMMON NAME: Many-ribbed sedge
3. FAMILY: Cyperaceae (Sedge family)
4. GENUS: According to Hermann (1970), there are at least 600 species of Carex in North America. in the Rocky Mountain region there are 165 species, making it the most diverse montane region for sedges. Differences among species are often small, and the group is not well understood by range ecologists (Hermann 1970) .
5. SPECIES: Carex multicostata is a western species of dry meadows and open woods in the mountains; it is more common in Oregon and California, but occurs east to Montana and north to Washington (Hermann 1970) .
B. PRESENT LEGAL OR OTHER FORMAL STATUS
1. FEDERAL STATUS
a. U.S. FISH AND WILDLIFE SERVICE: Carex multicostata is not currently listed in the U.S.F.W.S. Notice of Review (U.S. Department of Interior 1985) .
b. U.S. FOREST SERVICE: Carex multicostata is currently included on the Watch List for Region 1 (Northern Region) of the U.S. Forest Service (U.S. Department of Agriculture 1988) .
2. STATE: Carex multicostata is currently listed by the Montana Natural Heritage Program (Shelly 1989) as "critically imperiled in the state" (state rank = SI) . It is also included on the list of vascular plants of rare status by the Montana Rare Plant Project (Lesica et al. 1984) , indicating that it is either "limited to a resticted geographic range" or "occurs sparsely over a wider area in Montana." These state ranks do not currently provide any direct legal protection for Carex multicostata.
DESCRIPTION
1. GENERAL NONTECHNICAL DESCRIPTION: Carex multicostata is a tufted perennial sedge growing from short woody rootstocks. The flowers, which are reduced to ovaries and surrounding bracts and/or anthers subtended by scales, arise on angular stems above the flat green leaves and are tightly aggregated into light brown heads. The stems are ribbed.
2. TECHNICAL DESCRIPTION: Densely caespitose from short woody rootstocks; stout culms 3-9 dm, striate, surpassing the leaves; leaves flat, 2.5-6 mm wide, 3 or 4 per culm; spikes gynaecandrous, aggregated into oblong heads, 1.5-4 cm long and 14- 20 mm thick; scales ovate, obtuse to acute or slightly cuspidate, light reddish-brown with pale three-nerved center and broad hyaline margins; perigynia planoconvex, ovate, 3.5-5.5 mm long and 2-2.5 mm wide, subcoriaceous, green to straw- colored, wing-margined, serrulate to below the middle, conspicuously nerved dorsally, with a flat bidentate beak which is often winged and serrulate to the tip; achenes lenticular, 1.75-2.5 by 1.5 mm, yellowish or light-brown, substipitate (adapted from Hermann 1970) .
GEOGRAPHICAL DISTRIBUTION
1. RANGE: Carex multicostata occurs from Montana to Washington and south to California and Nevada.
2 . CURRENT SITES (MONTANA) : Carex multicostata is recently (1989) documented from one site in Montana. The species was collected on the Gallatin National Forest during the sensitive plant inventory of the Mill Creek Timber Sale area. It was found by a spring in the headwaters area of Counts Creek, along the road traversing the SW 1/4 of Section 14 of T6S, R9E. Additional location data are provided in the element occurrence print- out, p. 28, and the map, p. 29.
3. HISTORICAL SITES (MONTANA): Carex multicostata is known from only four other sites in Montana. Two collections have been made in Beaverhead County (1959) , and two collections are from Gallatin County (1921 and 1977).
HABITAT: Hermann (1970) lists the elevational range of Carex multicostata as 330 m (1000 ft.) to 3700 m (11000 ft.)« In Montana, the species is known from above timberline in the Bridger Range and from a large
27
subalpine (2400 m) meadow in the Mill Creek drainage of Park County (element occurrence 004) . The latter site is on a gentle (5%) north-facing slope at the upper edge of a former clearcut, and is associated with common montane and subalpine meadow species. It was growing with Deschampsia elongata in a moist seep.
ASSESSMENT AND MANAGEMENT RECOMMENDATIONS: Carex multicostata is listed as "critically imperiled in the state" by the Montana Natural Heritage Program (Shelly 1989) ,. and as a plant of rare status by the Montana Rare Plant Project (Lesica et al. 1984). It is not known how many individuals occur at the Counts Creek site, from which a single individual was collected. Because it occurs at a site where timber sale-related road improvements will take place, viability of the species in the area is possibly threatened. It is recommended that the area be further assessed for the extent and viability of the species before road expansion takes place.

These state ranks do not currently provide any direct legal protection for Eriqeron formosissimus.
31
C. DESCRIPTION
1. GENERAL NONTECHNICAL DESCRIPTION: Eriqeron formosissimus is a small perennial herb arising from a caudex anchored by a system of fibrous roots. A clump of slightly hairy leaves arises from the caudex. These leaves are longer than wide and are shaped like a spatula with rounded ends. Flowering stems arise from the center of the clump, and bear one to several blue or pink daisy-like heads and leaves which become smaller upwards towards the flowers. Leafy bracts subtending each head have many short glandular hairs and/or longer hairs without glands.
2. TECHNICAL DESCRIPTION: Medium perennial herb from a simple or branched caudex with fibrous roots; stems 1-4 dm, glandular above, often spreading- hirsute; basal leaves oblanceolate to oval, apices rounded, petiolate to subpetiolate, up to 15 cm long and 15 mm wide; cauline leaves reduced upwards, becoming sessile, lanceolate to ovate; heads 1-several, the disk 1-2 cm wide; involucre 5- 8 mm, glandular and often hirsute; rays 75-150, 8- 15 mm long and less than or equal to 1mm wide, blue, pink, or sometimes white; disk corollas 3.5- 4.4 nun long; achenes 2 -nerved (adapted from Cronquist 1955) .
D. GEOGRAPHICAL DISTRIBUTION
1. RANGE: Eriqeron f ormosissimus is found chiefly in the central and southern Rocky Mountains, occurring from South Dakota, Montana and Wyoming through Utah, Arizona and New Mexico, and extending into Mexico (Cronquist 1955) .
2. CURRENT SITES (MONTANA): Eriqeron formosissimus is recently documented (1989) from one site in Montana. The species was collected in the Gallatin National Forest near the headwaters of a tributary to Davis Creek, in the Mill Creek drainage. Location data are provided in the element occurrence print-out, p. 33, and on the map, p. 34.
3. HISTORICAL SITES (MONTANA): Five previous collections of E. formosissimus have been made in Montana, from 1919 to 1979. These were taken from Carbon, Gallatin, and Madison counties. The locations and status of these populations is currently unknown.
E. HABITAT
1. ASSOCIATED VEGETATION: Eriqeron formosissimus is a mountain species of meadows and open ground. Near Davis Creek (element occurrence 005) , plants were found in a conifer forest opening at about 2100 m (7000 ft.)- Species associated with E. formosissimus at this site include:
Dactylis qlomerata (orchardgrass) Hieracium gracile (slender hawkweed) Phleum alpinum (alpine timothy) Picea enqelmannii (Engelmann spruce) Pinus contorta (lodgepole pine) Pinus f lexilis (limberpine) Pseudotsuqa menziesii (Douglas-fir)
2. TOPOGRAPHY AND SOILS: Eriqeron formosissimus was collected on a lower slope of Chico Peak near the headwaters of a tributary to Davis Creek. Plants occur on a gentle (10%) north-facing slope at about 2100 m (7000 ft.). Soils are sandy and derived from metamorphic parent materials.
II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS
A. THREATS TO POPULATION: Eriqeron formosissimus occurs outside proposed harvest units of the Mill Creek Timber Sale, but at a site where road building would destroy known plants; however, habitat for regeneration would still exist.
B. RECOMMENDATIONS FOR FURTHER ASSESSMENT: Eriqeron formosissimus was collected during the survey for sensitive plants in the Mill Creek Timber Sale area. At the time of collection, the species was not recognized as a plant of rare status, and many pertinent population parameters were not noted. Further assessment of the size, viability and security of the population is recommended before road expansion takes place.
C. SUMMARY: Eriqeron formosissimus is recently (1989) documented from one site on the Gallatin National Forest. This site lies within the proposed Mill Creek Timber Sale, in an area designated for road expansion. Eriqeron formosissimus is not currently included on the list of sensitive plants for Region 1 of the U.S. Forest Service, but is listed as "critically imperiled in the state" by the Montana Natural Heritage Program (Shelly 1989) , and as a vascular plant of rare status by the Montana Rare Plant Project (Lesica et al. 1984). Further assessment of the population at the Mill Creek site is recommended.

Elenient Occurrence Record - Gallatin National Forest Montana Natural Heritage Program
SECTION TWO: Individual Sensitive Plant Surveys on the Gallatin National Forest.
INTRODUCTION
Six plant taxa of limited distribution in Montana that had previously been documented on the Gallatin National Forest were the focus of individual field surveys. Priority was given to species included on the U.S. Forest Service list of sensitive plants for Region 1 (Northern Region) . Section Two provides details of each survey, followed by recommendations for management and/or further research. Identification of field collections followed Dorn (1984) , Hitchcock and Cronquist (1973) Hitchcock et al. (1969) , and Hitchcock and Chase (1950) .
Acroseris sp. nov.
I. SPECIES INFORMATION
A. CLASSIFICATION
1. SCIENTIFIC NAME: Aqoseris sp. nov.
2. COMMON NAME: Pink agoseris
3. FAMILY: Asteraceae (Sunflower family)
4. GENUS: According to Cronquist (1955), there are seven species of Aqosetis occurring in the northwestern United States (not including the undescribed species discussed here) , and one species occurring in South America.
5. SPECIES: The Aqoseris species studied in this survey has not yet been formally described in the scientific literature, but the publication is in progress (Moseley et al. , in revision) . Specimens have been collected in Lemhi County, Idaho and Beaverhead, Deerlodge, Madison, Park and Sweet Grass counties, Montana.
B. PRESENT LEGAL OR OTHER FORMAL STATUS
1. FEDERAL STATUS
a. U.S. FISH AND WILDLIFE SERVICE: Aqoseris sp. nov. is not currently listed in the U.S.F.W.S, Notice of Review (U.S. Department of Interior 1985) .
b. U.S. FOREST SERVICE: Aqoseris sp. nov. is currently included on the list of sensitive species for Region 1 (Northern Region) of the U.S. Forest Service (U.S. Department of Agriculture 1988) .
2. STATE: Aqoseris sp. nov. is currently listed by the Montana Natural Heritage Program (Shelly 1989) as "critically imperiled in the state" (state rank = SI) . This state rank does not currently provide any direct legal protection for Aqoseris sp. nov. Through its inclusion on the Region 1 sensitive plant list, the taxon has legal protection under U.S. Forest Service agency policies (W. Ruediger, pers. comm. ) .
37
C. DESCRIPTION
1. GENERAL NONTECHNICAL DESCRIPTION: Aqoseris sp. nov. is a medium-sized perennial herb from a taproot. The crown may be simple or branched. Leaves all arise from the base, and 1-3 leafless flowering stems are produced. Leaves are smooth, thin, and longer than wide, and are 6-20 cm long. The acute leaf tips have a sharp, slender purple tip. Each flowering stem bears a single dandelion- like head of pink flowers. Below the heads are green bracts with purple mottling and woolly bases.
2. TECHNICAL DESCRIPTION: Perennial herb from a slender taproot; caudex simple or branched, producing a basal rosette and 1-3 scapes. Leaves oblanceolate, 6-20 cm long, 0.7-2.2 cm wide, entire to toothed distally, glabrous, apex acute, with a purple mucro, base narrowed to a long petiole; petiole narrowly to broadly winged, sheathing at the base, margins villous with spreading, multicellular hairs; scape 6-49 cm high, villous at the base, becoming tomentose beneath the solitary head; involucre campanulate, subequal, becoming imbricate in fruit; phyllaries lanceolate, in 3-4 series, inner acute, outer may be blunter and broader, light green with a purple medial stripe and purple mottling over all, outer ones densely villous at base; flowers all ligulate, 50-70 per head, perfect, light pink at emergence, drying to deep pink; achenes terete, gradually tapering to a slender beak; pappus double, of numerous capillary bristles (adapted from Moseley et al . , in revision) .
3. LOCAL FIELD CHARACTERS: Aqoseris sp. nov. is similar in habit to Aqoseris aurantiaca, a common species that is widespread in mountain meadows. The flowers of A. aurantiaca emerge burnt orange and often dry purplish in color. The flowers of Aqoseris sp. nov. are pink at emergence. The two species are also distinguishable on the basis of habitat; A. aurantiaca occurs in moist to dry, well-drained meadows, while Aqoseris sp. nov. is found in wet meadows where the soil is saturated through the growing season (Moseley et al . , in revision) .
D. GEOGRAPHICAL DISTRIBUTION
1. RANGE: Aqoseris sp. nov. is known from Lemhi
County, Idaho, and southwestern and southcentral Montana.
38
CURRENT SITES (GALLATIN NATIONAL FOREST) : Agoseris sp. nov. is recently documented (1989) from one site on the Gallatin National Forest, and was collected in 1980 from a second site on the Forest. The location of the population found in 1989 is provided in the element occurrence print-out on p. 40, and is indicated on the map on p. 41. Field surveys were conducted by the author on 31 July 1989 and 10 August 1989.
HISTORICAL SITES: The population of Agoseris sp. nov. represented by the 1980 collection was the focus of the 1989 field survey by the author. The collection (Lackschewitz 9421, MONTU) was made in the vicinity of Sunlight Peak in the Crazy Mountains. The survey was not successful, due to logistical difficulties encountered in trying to reach the site (the trail is washed out just below the pass from the Sunlight Creek drainage over to Sunlight Lake) . There was insufficient time for a second attempt to reach the area from the east side. The existing information on this population is provided in the element occurrence print-out on p. 42.
E . HABITAT
1. ASOCIATED VEGETATION: Agoseris sp. nov. occurs in wet meadows at high elevations. The site found in 1989 occurs in openings of Pinus albicaulis (whitebark pine) stands, with grasses, sedges and the following forbs:
Antennaria alpina (alpine pussytoes) Polygonum bistortoides (American bistort) Potentilla diversifolia (diverse-leaved cinquefoil) Veronica wormskjoldii (American alpine speedwell)
2. TOPOGRAPHY AND SOILS: At the currently documented site, Agoseris sp. nov. occurs on level ground at 2850 m. (9500 ft.). The subalpine meadow soils are saturated throughout the growing season.
POPULATION DEMOGRAPHY AND BIOLOGY
1. POPULATION SIZE AND CONDITION: The extent of the Agoseris sp. nov. population in the Haystack and Monument Peaks vicinity (occurrence 007) is unknown at this time. The species was found during a survey for another species, and time was not available for a full survey of the site. Much suitable habitat was observed in the area.
2. REPRODUCTIVE BIOLOGY: Many Agoseris species
39
reproduce by the sexual production of seeds. Single seeds are enclosed in achenes with persistent pappuses, which aid in airborne transport. The plants collected at the Haystack and Monument Peaks site were small, with unbranched caudices and single flowering stems. This suggests a relatively young age for the individuals collected, but may not reflect the age structure of the whole population.
G. LAND OWNERSHIP: Both populations of Aqoseris sp. nov. , as represented by the 1980 and 1989 collections, occur wholly on Gallatin National Forest lands.
II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS
A. THREATS TO KNOWN POPULATIONS (GALLATIN NATIONAL FOREST) : The meadows containing Aqoseris sp. nov. in the Haystack and Monument Peaks area lie just north, and outside, of the Absaroka-Beartooth Wilderness Area boundary. The area is frequented by trail bikers, who access the site via primitive roads leading to the abandoned Independence Mine.
B. FURTHER ASSESSMENT AND MANAGEMENT NEEDS: More detailed information regarding the occurrence and distribution of Aqoseris sp. nov. in Montana is needed. Little is known of the range and abundance of this species. Further surveys of likely mountain habitats could indicate whether Aqoseris sp. nov. is a typical subalpine meadow element, or whether it is truly rare, and restricted in both range and abundance. The Aqoseris sp. nov. population in the Haystack and Monument Peaks vicinity should be revisited for more detailed documentation. At the same time the impact of off-road vehicle use on the population should be assessed.
C. SUMMARY: Aqoseris sp. nov. is a species being newly described. Its extent and abundance in Montana, and on the Gallatin National Forest, is poorly known. Based on its occurrence in Lemhi County, Idaho and in counties of southwest and southcentral Montana, it could, at this time, be designated as a regional endemic' Aqoseris sp. nov. is known from two sites on the Gallatin National Forest. The size and condition of these populations is not fully documented at this time. Detailed documentation of both sites, and further surveys in other likely areas on the Gallatin National -Forest, are needed.

Aquileqia brevistyla
I. SPECIES INFORMATION
A. CLASSIFICATION
1. SCIENTIFIC NAME: AcmJlegia brevistyla Hook.
2. COMMON NAME: Small-flowered columbine
3. FAMILY: Ranunculaceae (Buttercup family)
4. GENUS: According to Hitchcock and Cronquist (1964) , there are nearly 70 species of Aquileqia . They are distributed in the Northern Hemisphere and are mostly montane.
5. SPECIES: Aquileqia brevistyla is a far northwestern species, occurring in Alaska and extending across northern British Columbia and Alberta to Wyoming, Montana and South Dakota.
B. PRESENT LEGAL OR OTHER FORMAL STATUS
1. FEDERAL STATUS
a. U.S. FISH AND WILDLIFE SERVICE: Aquileqia brevistyla is not currently listed in the U.S.F.W.S. Notice of Review (U.S. Department of Interior 1985) .
b. U.S. FOREST SERVICE: Aquileqia brevistyla is currently included on the list of sensitive species for Region 1 ( Northern Region) of the U.S. Forest Service (U.S. Department of Agriculture 1988) .
2. STATE: Aquileqia brevistyla is currently listed by the Montana Natural Heritage Program (Shelly 1989) as "critically imperiled in the state" (state rank = SI) . This state rank does not currently provide any direct legal protection for A. brevistyla. Through its inclusion on the Region 1 sensitive plant list, the taxon has legal protection under U.S. Forest Service agency policies (W. Ruediger, pers. comm. ) .
C. DESCRIPTION .
1. GENERAL NONTECHNICAL DESCRIPTION: Aquileqia
brevistyla is a slender perennial herb with few branches. Plants have a cluster of leaves from the
44
base on long stems, and a few leaves on the flowering stem on very short stems. The basal leaves are divided into six lobed segments, while the stem leaves are merely lobed. The showy blue and white flowers often hang downward on curved stems. The flowers have five blue sepals and five white petals which have tubular extensions, or spurs. The spurs of A. brevistyla are relatively short, and are hooked at the ends. Plants bloom in June and July.
2. TECHNICAL DESCRIPTION: Slender perennial herb, 2- 8 dm, sparingly branched, glabrous to glandular and pubescent; basal leaves triternate, on long petioles; stem leaves few, lobed, nearly sessile; flowers showy, 1.5-2.5 cm long, nodding or ascending; sepals 5, blue to purple, oblong- lanceolate, clawed; petals creamy white, blades about same length as sepals, spur bluish, hooked, 6-8 mm long; styles and stamens only slightly exceeding the petals; stamens many; follicles 5, pubescent, 2-2.5 cm long, their beaks 2-5 mm long (adapted from Hitchcock and Cronquist 1964, Moss 1959) .
3. LOCAL FIELD CHARACTERS: Aquileqia brevistyla is similar in habit and habitat to the other columbines encountered in southwestern Montana. Aquileqia flavescens (yellow columbine) , probably the species most commonly encountered, has yellow to pinkish flowers with long, slightly incurved spurs. Aquileqia coerulea (Colorado columbine) , another species with blue and white flowers, also occurs on the Gallatin National Forest. It is distinguished from A. brevistyla by its longer spurs (2-4 cm) which are nearly to quite straight. All three species may be found in woodland or meadow habitats, and in rock crevices.
D. GEOGRAPHICAL DISTRIBUTION
1. RANGE: Aquileqia brevistyla is a species of northwestern North America, occurring from Alaska to northern British Columbia, across Alberta to Wyoming, Montana and South Dakota.
2. CURRENT SITES (GALLATIN NATIONAL FOREST): There are no currently documented occurrences of Aquileqia brevistyla on the Gallatin National Forest.
3. HISTORICAL SITES: One collection, made in 1967 from the Boulder River above McLeod, may represent a population of A. brevistyla. The specimen.
45
collected by L. Thornton (no accession or collection number; housed at MONT, Bozeman) , was pressed in such a way that it is difficult to properly measure the flower parts for positive identification. The area of this collection was surveyed by the author on 28-30 July 1989. No populations of either A. brevistyla or A. coerulea were found, although A. f lavescens was frequently observed. The existing information for this record is provided in the element occurrence print-out on p. 47.
4. AREAS SURVEYED BUT TAXON NOT LOCATED: The
following areas along the Boulder River, in the vicinity of the 1967 collection, were surveyed for Aquileqia brevistyla. The area from Hell's Canyon Campground to Hick's Park Campground was surveyed less extensively than the area below Hell's Canyon. Areas actually surveyed were smaller in most cases than the portions of the sections listed, as the survey was concentrated on riverbanks and nearby woodland habitats.

E. HABITAT: According to Moss (1959) , Aquileqia brevistyla is a species of meadows, open woods and rock crevices, "occurring occasionally throughout . . . forested areas" within its range.
F. LAND OWNERSHIP: Lands along the Boulder River are under both private and U.S. Forest Service ownership. It is not certain whether the 1967 collection was taken from public or private lands.
II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS
A. THREATS: Lands along the Boulder River are heavily used for recreation and firewood cutting. Either activity might alter the habitat in such a way as to threaten
viability of a population of Aquileqia brevistyla.
B. RECOMMENDATIONS FOR FURTHER ASSESSMENT: Although the lands along the Boulder River "20 miles above the town of McLeod" were extensively searched during the 1989 survey, Aquileqia brevistyla was not found, nor was A. coerulea. For an A. brevistyla survey, timing was correct. The species blooms primarily in June, and the Boulder River collection was made 4 July 1967. If the 1967 collection actually represents A. coerulea, plants could bloom as late as August, and the timing of further surveys should be extended across the growing season. Another consideration in planning future surveys is the very general nature of the location data given for the 1967 collection. The herbarium label states that the plant was collected "along the Boulder River, 20 miles above the town of McLeod," While this vicinity might again be a good starting point, it is difficult to know whether the label mileage was estimated, or clocked on an odometer. Consideration was given to the question of whether the main Boulder River, or its east or west forks, were actually visited by the collector. It was decided that the main Boulder River was correct, and the survey was conducted in that drainage.
C. SUMMARY: Aquileqia brevistyla is a northwestern North American species that may have its southernmost occurrence along the Boulder River in Sweet Grass County, Montana. While Hitchcock et al. (1969) state that the species is "probably not to be found in our area," an Aquileqia brevistyla specimen of undisputed identity, from Judith Basin County, Montana, is housed in the Montana State University Herbarium (MONT #51788) . A population of A. brevistyla. represented by the 1967 historical collection, was not relocated during surveys in 1989. Given the heavy use of the main Boulder River drainage by recreationists and firewood cutters, further surveys for this species are called for so that possible threats can be identified and mitigated.

Balscimorhiza macrophylla
SPECIES INFORMATION
A. CLASSIFICATION
1. SCIENTIFIC NAME: Balsamorhiza macrophylla Nutt.
2. COMMON NAME: Large-leaved balsamroot
3. FAMILY: Asteraceae (Sunflower family)
4. GENUS: There are approximately 12 species in the genus Balsamorhiza (Cronquist 1955) , all occurring in western North America. Two members of the genus are widespread in the northern Rocky Mountain region: B. saqittata and B. incana .
5. SPECIES: Balsamorhiza macrophylla is a Great Basin species that reaches its northern range limit in Gallatin County, Montana. Cronquist (1955) notes that "any two species will hybridize where they grow together" due to the lack of strong genetic barriers. However, no obvious hybrids were noted in the Montana population of B. macrophylla . where B. saqittata also occurs.
B. PRESENT LEGAL OR OTHER FORMAL STATUS
1. FEDERAL STATUS
a. U.S. FISH AND WILDLIFE SERVICE: Balsamorhiza macrophylla is not currently listed in the U.S.F.W.S. Notice of Review (U.S. Department of Interior 1985) .
b. U.S. FOREST SERVICE: Balsamorhiza macrophylla is currently included on the list of sensitive plant species for Region 1 (Northern Region) of the U.S. Forest Service (U.S. Department of Agriculture 1988) .
2. STATE: Balsamorhiza macrophylla is currently listed by the Montana Natural Heritage Program (Shelly 1989) as "critically imperiled in the state" (state rank = SI) . This state rank does not currently provide any direct legal protection for B. macrophylla. Through its inclusion on the Region 1 sensitive plant list, the taxon has legal protection under U.S. Forest Service agency policies (W. Ruediger, pers. comm.).

C. DESCRIPTION
1. GENERAL NONTECHNICAL DESCRIPTION: Balsamorhiza macrophvlla is a robust perennial herb arising from a large taproot. Several branches may surmount the taproot. The large (3-6 dm) lobed leaves are clustered at the base and may be sparsely to evidently hairy with long hairs. One to several large sunflower-like heads arise from the center. The heads consist of yellow tubular flowers in the center surrounded by yellow ray flowers which are 3.5-5.5 cm long. Montana plants bloom in June and July.
2. TECHNICAL DESCRIPTION: Robust perennial herb from a taproot surmounted by erect branches arising underground; leaves 3-6 dm long divided into large few-toothed to entire segments 5-12 cm long, glandular below, sparsely to evidently hirsute above; stems 3-10 dm; heads large, subtended by long, leafy bracts which may surpass the disk; achenes glabrous (adapted from Cronquist 1955) .
3. LOCAL FIELD CHARACTERS: Balsamorhiza macrophvlla is easily distinguished from the more common B. saqittata by its segmented leaves. In addition, the leaves of B. macrophvlla lack the dense leaf pubescence of B. saqittata. and therefore appear greener.
D. GEOGRAPHICAL DISTRIBUTION
1. RANGE: Balsamorhiza macrophvlla is a Great Basin species occurring in the Wasatch area of northern Utah, extending into the mountains of southeast Idaho, through western Wyoming to the edge of the Snake River plains, then extending east to Clark County, Idaho and north to Gallatin County, Montana (Cronquist 1955) .
2. CURRENT SITES (MONTANA): Balsamorhiza macrophvlla is currently known from only one site in Montana. This site occurs on Gallatin National Forest lands. Location data are provided in the element occurrence print-out, p. 53, and the population location is indicated on the map on p. 54. Photographs are provided on pp. 55-56. Field surveys were conducted by the author and Lisa Schassberger (Montana Natural Heritage Program) on 16 June 1989, and by the author on 5-6 July 1989, 3 August 1989, and 24 August 1989.
3. HISTORICAL SITES (MONTANA): Two collections of Balsamorhiza macrophvlla from the Gallatin National
Forest exist in the Montana State University Herbarium (MONT) , Bozeman. It is believed that the survey in the vicinity of the Cinnamon Creek Ranger Station was successful in relocating the June 1928 collection from this area. The second collection was from the Cabin Creek area, north of Hebgen Lake, in July 1931. An extensive survey to relocate the population represented by the latter collection was not successful. There is much seemingly suitable meadow habitat in the Cabin Creek drainage, although these sites vary in both exposure and species composition from the site where Balsamorhiza macrophvlla was found in the vicinity of Cinnamon Creek. The collection predates the 1959 earthquake, which noticeably affected the Cabin Creek scarp. The existing information for this historical record is provided in the element occurrence print-out on p. 57.
4. AREAS SURVEYED BUT TAXON NOT LOCATED: Habitats in the vicinities of the historical collections which appeared suitable on topographic maps were surveyed and are listed below:
a. T8S, R4E, Section 22, SW 1/4, SE 1/4
Section 27, NW 1/4 Section 28, NE 1/4, SE 1/4
b. TllS, R3E, Section 1, NW 1/4, NE 1/4, SE 1/4 TllS, R4E, Section 6, NW 1/4, SW 1/4
Section 5, NE 1/4, NW 1/4, SE 1/4 Section 4, SW 1/4
HABITAT
ASSOCIATED VEGETATION: In the Cinnamon Creek vicinity, Balsamorhiza macrophylla occurs on two types of sites. The main population is found in a sagebrush-forb community on a gently sloping open ridgetop. Outliers are scattered through the Douglas-f ir/lodgepole pine forest, and in meadow openings on east-facing slopes below. The lower sites are steeper and rockier and support a different combination of plant species. Species associated with the main ridgetop population include:
Artemisia tridentata (big sagebrush) Castilleia miniata (scarlet paintbrush) Delphinium bicolor (little larkspur) Delphinium occidentale (western larkspur) Festuca sp. (fescue)
Geranium viscosissimum (sticky geranium) Heracleum lanatum (cow-parsnip)
LithophracfKia parvif lora (smallf lowered fringecup)
Lomatium triternatum (nine-leaf lomatium)
Lupinus arqenteus (silvery lupine)
Melica spectabilis (showy oniongrass)
Myosotis alpestris (wood forget-me-not)
Poa sp. (bluegrass)
Populus tremuloides (aspen)
Potentilla gracilis (slender cinquefoil)
Plant species associated with the scattered subpopulations include:
Amelanchier alnifolia (western snowberry) Antennaria microphylla (rosy pussytoes) Arenaria conqesta (capitate sandwort) Artemisia tridentata (big sage) Balsamorhiza sagittata (arrowleaf balsamroot) Berberis repens (creeping Oregongrape) Bromus carinatus (California brome) Danthonia unispicata (onespike danthonia) Eriogonum umbellatum (sulfurf lower) Juniperus communis (common juniper) Microseris nutans (nodding microseris) Poa pratensis (Kentucky bluegrass) Pseudotsuga menziesii (Douglas-fir)
2. TOPOGRAPHY AND SOILS: Populations of Balsamorhiza macrophvlla in the Cinnamon Creek vicinity occur on open east-facing slopes, from 2300 m. (7100 ft.) to 2500 m. (7400 ft.)* The slope supporting the main population is gentle (8-15%) . The soil is loamy and without rocks. The plant community indicates a moderately moist site. Subpopulations are found on 45% slopes where the soils are rockier with more clay, and tend to be more closely associated with Douglas-fir trees or saplings which are scattered in the openings.
F. POPULATION DEMOGRAPHY AND BIOLOGY
1. REPRODUCTIVE BIOLOGY: Balsamorhiza macrophvlla reproduces by seed. Seeds give rise to plants producing large taproots and which become relatively long-lived perennials.
2. POPULATION SIZE AND CONDITION: The main population of Balsamorhiza macrophylla at Cinnamon Creek consists of well over 1000 individuals.- The subpopulations together total around 100 plants.
It was estimated that at least 10% of the total is made up of young plants, i.e., those in leaf only and with unbranched crowns. Mature plants were vigorous.
3. BIOLOGICAL INTERACTIONS: It was noted that
Balsamorhiza sagittata is associated with the main population of Balsamorhiza macrophylla only at its lower edge where it meets the forest boundary. On the steeper, rockier sites where subpopulations of Balsamorhiza macrophylla are found, B. sagittata is the more common species. No hybridization was evident.
II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS
A. THREATS TO THE POPULATION: Braided horse trails are extensive on the lower, steeper slopes where the subpopulations occur. The associated erosion and mechanical damage are the most serious threats to the Balsamorhiza macrophylla population. The main trail from the Cinnamon Creek Ranger Station to Taylor Fork winds through the ridgetop population of B. macrophylla. The trail is used by both trail bikers and horseback riders. Off trail riding by either of these users poses a threat of physical damage to the population.
B. RECOMMENDATIONS FOR MAINTAINING VIABLE POPDALTIONS: The braided trails are presumably made by riders from the 320 Ranch traveling the slopes upward to join the ridgetop trail to Taylor Fork. Provision of a single well-marked trail skirting the lower Balsamorhiza macrophylla populations would very simply avoid further damage to them. In a similar way, trail bikers were observed crossing the terrain off trail from their starting point at the Cinnamon Creek Ranger Station until they found the main trail. Monitoring of off- trail use should be a priority.
C. RECOMMENDATIONS FOR FURTHER ASSESSMENT: The trail to Taylor Fork should provide good access to meadows in T9S, R4E, Sections 3 & 4, which may be likely habitat for Balsamorhiza macrophylla. Further surveys along the Middle and South forks of Cabin Creek are also recommended.
D. SUMMARY: Balsamorhiza macrophylla is a Great Basin and Snake River Plains species that has its northernmost known occurrence in Montana, in the vicinity of Cinnamon Creek Ranger Station on the Gallatin National Forest. While there is much seemingly suitable habitat for the species between this disjunct site and the main range of the species, Balsamorhiza macrophylla has not been recently recorded at other sites in Montana. The single population currently known in Montana occurs on Gallatin National Forest lands, and could easily be protected at this time following the recommendations made above.

Castilleia qracillima
I. SPECIES INFORMATION
A. CLASSIFICATION
1. SCIENTIFIC NAME: Castilleia qracillima Rydb .
2. COMMON NAME: Slender paintbrush
3. FAMILY: Scrophulariaceae (Figwort family)
4. SPECIES: Castilleia qracillima is a narrowly distributed species found in northwest Wyoming, adjacent Montana and central Idaho. According to Ownbey (Hitchcock et al. 1959) , C. qracillima has affinities with C. sulphurea and C. miniata , but is distinguishable from them.
5. GENUS: Castilleia consists of 150-200 species (Hitchcock et al. 1959) , distributed in western North and South America. The greatest number of species occurs in the western United States. Hybridization and polyploid complexes are common in the genus, and are the source of taxonomic difficulties.
B. PRESENT LEGAL OR OTHER FORMAL STATUS
1. FEDERAL STATUS
a. U.S. FISH AND WILDLIFE SERVICE: Castilleia qracillima is not currently listed in the U.S.F.W.S. Notice of Review (U.S. Department of Interior 1985) .
b. U.S. FOREST SERVICE: Castilleia qracillima is currently included on the list of sensitive species for Region 1 (Northern Region) of the U.S. Forest Service (U.S. Department of Agriculture 1988) .
2. STATE: Castilleia qracillima is currently listed by the Montana Natural Heritage Program (Shelly 1989) as "possibly in peril in the Montana, status uncertain; more information needed" (state rank = SU) . This state rank does not currently provide any direct legal protection for C. qracillima. Through its inclusion on the Region 1 sensitive plant list, the taxon has legal protection under U.S. Forest Service agency policies (W. Ruediger, pers. comm. ) .
59
C. DESCRIPTION
1. GENERAL NONTECHNICAL DESCRIPTION: Castille-ia qracillima is a perennial herb with slender stems arising more or less distantly from one another. The stems are usually unbranched and grow 2-5 dm tall. Leaves are longer than wide and may be lance-shaped, or they may be narrower and have sides which are parallel to one another. Stems and leaves are smooth to hairy. The inflorescence is made up of green tubular flowers, each with two lips. The upper lip forms an extension nearly as long as the tubular portion, and the lower lip is reduced to three small teeth. Below each flower is an oblong bract which is yellow to orange. In Montana, plants bloom from late June to August.
2. TECHNICAL DESCRIPTION: Slender perennial from a rhizome or remote woody caudex, 2-5 dm, usually unbranched, glabrous to villous; leaves entire, linear to lanceolate; inflorescence yellow to orange or sometimes red; bracts oblong, entire to lobed distally with a pair of lateral lobes, villous-puberulent; calyx 15-22 mm, deeply subequally cleft above and below, the primary lobes divided into 2 acute segments 2-4 mm long; corolla 20-30 mm, galea densely puberulent, shorter than the tube and about 5 times as long as the dark green lower lip (adapted from Hitchcock et al. 1959) .
D. GEOGRAPHICAL DISTRIBUTION
1. RANGE: Castilleja qracillima is a regional endemic occurring in northwestern Wyoming and adjacent Montana, and extending to central Idaho.
2. CURRENT SITES (GALLATIN NATIONAL FOREST): Castilleja qracillima is known from two sites on the Gallatin National Forest. Both sites are near the boundaries of Yellowstone National Park, one along Grayling Creek, and the other on the Gallatin River. Location data providing legal and topographic details are provided in the element occurrence print-outs, pp. 64 and 66, and the maps, pp. 65 and 67. Photographs are provided on pp. 68- 69. Between these two sites, populations of C. qracillima occur along both drainages on Yellowstone National Park lands. Field surveys were conducted by the author on 7 July 1989 and 2 August 1989.
3. HISTORICAL SITES (GALLATIN NATIONAL FOREST): Two historical collections of Castilleia qracillima
60
represent populations occurring on Gallatin National Forest lands. It is believed that the site of the original Grayling Creek population was rediscovered in the July 1989 survey. A second historical site was recorded in the Gallatin Canyon at "Daly Creek." There is a Dailey Creek joining the Gallatin River on Yellowstone Park lands. The lands to the west of the river in this vicinity are State of Montana lands (Gallatin Wildlife Management Area) or Gallatin National Forest lands. No populations of C. qracillima were located in this area, on Forest, State or Park lands. The site is represented by a poor specimen of uncertain identification (RM #70471) . Descriptive data for the historical site ("10% east slope. Shallow coarse soil. Woodland.") is not characteristic of sites where C. qracillima is found.
4. AREAS SURVEYED BUT TAXON NOT LOCATED: Suitable habitat along the Gallatin River, from the Yellowstone National Park boundary to Big Sky, was surveyed for Castilleja qracillima. The population near Snowflake Springs (007) was the only one located along the Gallatin River outside Yellowstone National Park.
E. HABITAT
ASSOCIATED VEGETATION: Castilleja qracillima occurs in wet meadows where the soil is saturated during at least part of the growing season. Species found growing with C. qracillima at the Grayling Creek site include:
Arnica chamissonis ssp. foliosa (leafy arnica)
Astraqalus miser (weedy milk-vetch)
Carex spp. (sedges)
Castilleja miniata (scarlet paintbrush)
Epilobium qlaberrimum (smooth willow-herb)
Equisetum sp. (horsetail)
Geranium richardsonii (white geranium)
Geum macrophvllum (largeleaved avens)
Habenaria dilatata (white bog-orchid)
Lonicera involucrata (bearberry honeysuckle)
Pedicularis qroenlandica (elephant's head)
Phleum pratense (timothy)
Potentilla qracilis (slender cinquefoil)
Prunella vulqaris (self-heal)
Salix spp. (willows)
Plant species associated with Castilleja qracillima at the Snowflake Springs site include:
Artemisia tridentata (big sagebrush)
61
Betula glandulosa (bog birch)
Campanula rotundifolia (harebell)
Castilleia miniata (scarlet paintbrush)
Eriogonum umbel latum (sulfurf lower)
Galium boreale (northern bedstraw)
Gentianopsis detonsa (fringed gentian)
Geranium richardsonii (white geranium)
Geum macrophvllum (largeleaved avens)
Habenaria hyperborea (northern green bog-orchid)
Heracleum lanatum (cow-parsnip)
Mimulus quttatus (yellow monkey-flower)
Potentilla fruticosa (shrubby cinquefoil)
Rhamnus alnifolia (alder buckthorn)
Rorippa nasturtium-aqua ticum (water-cress)

Salix wolf ii (Wolf's willow)
Senecio crassulus (thick-leaved groundsel)
Senecio serra (butterweed groundsel)
Solidaqo canadensis (Canadian goldenrod)
Symphoricarpos albus (snowberry)
2. TOPOGRAPHY AND SOILS: Castilleja qracillima was found to occur at the edges of running water, on stream or river bottoms, or on slopes of nearly 10% at Snowflake Springs. Streamside or bottom sites are sandy or gravelly, while the Snowflake Springs site occurs on a vegetated limestone terrace that was deposited by the springs.
F. POPULATION BIOLOGY, DEMOGRAPHY T^D ECOLOGY
1. PHENOLOGY AND REPRODUCTIVE BIOLOGY: Castilleja qracillima blooms from June to August in Montana. The inflorescence elongates as fruiting begins, the bracts remaining colorful through July as seed set begins. Castillejas produce many seeds following out-crossing with other individuals. Hummingbirds and insects are the usual pollination agents. The seeds are very light and easily airborne. Castilleia qracillima is one of the few species that is at least partially rhizomatous. New individuals may therefore arise as a result of either sexual or vegetative reproduction.
2. POPULATION SIZE AND CONDITION: Populations of Castilleia qracillima were observed to be vigorous, but restricted in the area they covered. Up to 1000 plants occur at the Snowflake Springs site, covering an area of 2-5 acres. This estimate is based on the number of ramets (above-ground stems) rather than genets (separate individuals) , as individual genets are not easily discernible without knowledge of the root system. The Grayling Creek site supports 100-500 plants on a small sandy
62
peninsula approximately 150 square meters in area, and in meadows close to the peninsula.
3. BIOLOGICAL INTERACTIONS: It is difficult to define the factors restricting the distribution of Castilleia qracillima. Competition is not easily observed, and soil moisture is more likely to be a limiting factor. Castilleias are subject to herbivory by noctuid larvae; however, C. qracillima does not seem to be as heavily fed upon as many other species (pers. obs.). Hybridization is common amongst Castilleia species, and is possibly responsible for some of the more robust, non- rhizomatous members of the observed populations.
G. LAND OWNERSHIP: Along Grayling Creek, Castilleia
qracillima occurs on both U.S. Forest Service lands and Yellowstone National Park lands. The population at Snowflake Springs may occur at least partially on private lands that border the springs to the north. The smaller subpopulations, along the Gallatin River toward the Park boundary, are on Gallatin National Forest lands or State of Montana lands (Gallatin Wildlife Management Area) .
II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS
A. THREATS TO POPULATIONS: Populations of C. qracillima appear to be stable at this time. The most likely threats would stem from environmental rather than man- caused events. Disturbance and re-establishment probably occur at relatively frequent intervals due to the stream and river bank habitats where populations occur.
B. RECOMMENDATIONS FOR MAINTAINING VIABLE POPULATIONS: Recreation in the form of fishing is the main use of the two Gallatin National Forest sites where C. qracillima is known to occur. No altered management practices seem to be called for at this time. Should further surveys reveal populations in drainages where livestock grazing takes place, monitoring of such populations would be called for to assess whether or not livestock use posed a threat.
C. RECOMMENDATION FOR FURTHER ASSESSMENT: Castilleia qracillima occurs in Yellowstone National Park in saturated meadow habitats not so closely associated with major drainages. Similar habitats in the southern regions of the Gallatin National Forest may also support populations of C. qracillima. Potential sites could be located with the use of topographic maps, and subsequently surveyed.
63
D. SUMMARY: CastJlleja qracillima is a regional endemic known from only two sites on the Gallatin National Forest. Because much of the Gallatin National Forest does occur within the range of the species, further surveys are called for to assess the rarity or abundance of the species on Forest lands.

I. SPECIES INFORMATION A. CLASSIFICATION
1. SCIENTIFIC NAME: Eriqeron eatonii (Gray) Howell var. eatonii
2. COMMON NAME: Eaton's daisy
3. FAMILY: Asteraceae (Sunflower family)
4. GENUS: According to Cronquist (1955), there are approximately 200 species of Eriqeron, 130 of which are centered in the western Cordillera in North America north of Mexico.
5. SPECIES/VARIETY: Eriqeron eatonii is a species of mountains and foothills, occurring from northern Arizona to northern Wyoming and adjacent Montana, and west into central Washington and California. Cronquist (1955) recognizes three varieties, each occupying different portions of the species' range. Variety eatonii is found from southwest Montana, Wyoming and southern Idaho southward. Variety villosus is found in central and western Idaho, southern Oregon and Washington, while var. plantaqineus occurs in California, adjacent Nevada and southern Oregon.
PRESENT LEGAL OR OTHER FORMAL STATUS
1. FEDERAL STATUS
a. U.S. FISH AND WILDLIFE SERVICE: Eriqeron
eatonii var. eatonii is not currently listed in the U.S.F.W.S. Notice of Review (U.S. Department of Interior 1985) .
b. U.S. FOREST SERVICE: Eriqeron eatonii var. eatonii is currently included on the list of sensitive plant species for Region 1 (Northern Region) of the U.S. Forest Service (U.S. Department of Agriculture 1988) .
2. STATE: Eriqeron eatonii var. eatonii is currently listed by the Montana Natural Heritage Program (Shelly 1989) as "critically imperiled in the state" (state rank = SI) . This state rank does not currently provide any direct legal protection. Through its inclusion on the Region 1 sensitive plant list, the taxon has legal protection under
71
U.S. Forest Service agency policies (W. Ruediger, pers. comm. ) .
C. DESCRIPTION
1. GENERAL NONTECHNICAL DESRIPTION: Eriqeron eatonii var. eatonii is a medium-sized perennial herb (5-
3 0 cm) from a taproot. The stems and foliage have appressed hairs. A tuft of leaves, each with three veins, arises from the base of the plant. These leaves are longer than wide, are sharp at the tip and narrowed at the base. The flowering stems arise from the center of the plant, bearing 1-7 daisy-like heads and several much smaller leaves. The heads bear many white ray flowers that surround the center of yellow disk flowers.
2. TECHNICAL DESCRIPTION: Perennial from a taproot, 5-30 cm, with appressed hairs; stems decumbent and purplish at the base; basal leaves tufted, triple- nerved, entire, acute, tapering to a long petiole; stem leaves several, reduced; heads 1-7, the involucre 5-7 mm, distinctly imbricate and glandular and sometimes slightly hirsute; rays 20- 50, mostly white, 5-10 mm long, 1-3 mm wide; disk corollas 3.5-5 mm long; inner pappus bristles 15- 2 0 or 25, the outer setose and obscure (adapted from Cronquist 1955) .
D. GEOGRAPHICAL DISTRIBUTION
1. RANGE: Eriqeron eatonii var. eatonii is the northeasternmost-occurring variety of Eriqeron eatonii. It ranges southward from southwest Montana, Wyoming and southern Idaho.
2. CURRENT SITES (GALLATIN NATIONAL FOREST): No populations of Eriqeron eatonii var. eatonii are currently documented on the Gallatin National Forest.
3. HISTORICAL SITES: One collection of Eriqeron eatonii var. eatonii was made from the Haystack Peak area, and represents the only known occurrence of the variety on the Gallatin National Forest (and in Montana). The specimen was taken by C.L. Hitchcock and C.V. Muhlick (13414) on 8 August 1945. The population represented by this collection was the focus of a survey by the author on 31 July 1989, but the plants were not relocated. The existing information for this historical record is provided in the element occurrence print-out on p. 73.
72
4. AREAS SURVEYED BUT TAXON NOT LOCATED: Haystack Peak is in the northwest 1/4 of section 26, TVS, R12E. Personnel from the Big Timber Ranger District provided transportation to the Haystack Peak area, and the area at the north base of the mountain was surveyed. This was in accordance with the herbarium label location data. Data from the label specifically reads, "Stillwater County... at north base of Mt. Haystack, head of Boulder Creek." Haystack Peak and the Boulder River are in adjacent Sweet Grass County, but the county boundaries are listed as indefinite on the 1942 Cutoff Mountain Quadrangle (USGS 15' series).
E. LAND OWNERSHIP: If the population represented by
the 1945 collection is relocated in a future survey at the north base of Haystack Peak, it would lie wholly on Gallatin National Forest lands, and within the Absaroka- Beartooth Wilderness Area.
RECOMMENDATIONS FOR FURTHER ASSESSMENT: Haystack Peak is truly at the head of neither the Boulder River nor the East Boulder River. It is uncertain what the collectors meant by "head of Boulder Creek." Sheepherder Peak, to the south of Monument and Haystack peaks, is closer to the vicinity of the heads of both rivers. If further surveys are conducted in the area, the heads of both drainages at the base of Sheepherder Peak might be checked, along with more extensive surveys of the Haystack and Monument peaks area.
SUMMARY: In Montana, Eriqeron eatonii var. eatonii is a taxon occurring at the edge of the range for both the species and the variety. A single historical collection documents the occurrence of the species on the Gallatin National Forest. A survey to relocate this population in 1989 was unsuccessful.

C. DESCRIPTION
1. GENERAL NONTECHNICAL DESCRIPTION: Salix wolfii
75
var. wolf ii is a low, spreading shrub of stream and river banks, growing to a maximum height of 2 meters. The leaves are on short stems with evident leafy stipules at their bases. The leaf blades have smooth margins, and are longer than wide, with sharpish tips. They may be as long as 4.5 cm and as wide as 1.5 cm. Leaves are silky with soft, long appressed hairs, appearing grayish, usually more so below than above. The catkins appear at the same time as the leaves, on short leafy stems. Male catkins are 1-2 cm long and usually less than 1 cm thick. Female catkins are 1.5-4 cm long. Both catkins bear dark brown or black scales which are persistent and woolly. Capsules of the female catkins are hairy.
2. TECHNICAL DESCRIPTION: Freely branched shrub from 6-20 dm tall; current season twigs sparsely villous-puberulent ; leaves with petioles 2-10 mm long and foliaceous stipules 1-5 mm long which may be glandular-serrate and are sooner or later deciduous; leaf blades entire, acute, elliptic, 3- 4.5 times as long as wide, up to 4.5 cm long and 1.5 cm wide, sparsely to densely sericeous; aments coetaneous on short leafy-bracted peduncles, bracts often over 1 cm; scales dark-brown to black, persistent, woolly-villous; staminate aments 1-2 cm long, usually less than 1 cm wide; stamens 2, filaments glabrous; pistillate aments 1.5-4 cm long; capsules 3.5-5 mm long, villous-puberulent, pedicels under 1 mm; style 0.5-1.1 mm long, longer than the short, bilobed stigma (adapted from Hitchcock and Cronquist 1964) .
3. LOCAL FIELD CHARACTERS: Salix wolfii var. wolfii forms low, spreading bushes, often not much taller than surrounding sedges and grasses and usually less than waist high. The pubescence of the leaves reflects light and gives the shrubs a silvery- grayish look.
D. GEOGRAPHICAL DISTRIBUTION
1. RANGE: Salix wolfii var. wolfii occurs mainly in Colorado, northeast Utah and Wyoming, entering southwest Montana and eastern Idaho.
2. CURRENT SITES (GALLATIN NATIONAL FOREST): Salix volfii var. wolfii is recently documented (1989) from two sites on the Gallatin National Forest. These sites occur wholly or partially on U.S. Forest Service lands. Locations, including legal and topographic data, are provided in the element occurrence print-outs, pp. 78 and 80, and on the
76
maps on pp. 79 and 81. Photographs are provided on pp. 82-83. Field surveys were conducted by the author on 6-7 July 1989 and 2 August 1989.
HISTORICAL SITES (GALLATIN NATIONAL FOREST) : A survey at the Cinnamon Creek Ranger Station was successful in relocating a population of Salix wolf ii var. wolf ii collected in 1947. Extending the survey from Cinnamon Creek to the nearby Gallatin River confirmed the occurrence of the species there as well.
E. HABITAT
ASSOCIATED VEGETATION: Salix wolfii var. wolfii occurs on streambanks and low ground where the vegetation is dominated by other willows, bog birch, grasses and sedges. Plants associated with S. wolfii var. wolfii along Cinnamon Creek include;
Aqrostis variabilis (variant bentgrass)
Artemisia ludoviciana (prairie sage)
Aster eatonii (Eaton's aster)
A. foliaceus (leafy aster)
Astragalus americanus (American milk-vetch)
Betula qlandulosa (bog birch)
Castilleia miniata (scarlet paintbrush)
Gentiana af finis (pleated gentian)
Geum macrophyllum (largeleaved avens)
Glyceria elata (tall mannagrass)
Heracleum lanatum (cow-parsnip)
Mimulus quttatus (yellow monkey-flower)
Phleum pratense (timothy)
Potentilla fruticosa (shrubby cinquefoil)
P. gracilis (slender cinquefoil)
Ribes inerme (whitestem gooseberry)
Symphoricarpos albus (snowberry)
TOPOGRAPHY AND SOILS: Salix wolfii var. wolfii occurs at elevations from 1900 to 2000 m (6400 to 6600 ft.). Populations were found on low ground associated with streams and riverbanks, in places where the soil is likely to be saturated during at least part of the growing season. Soils were either loams or sandy loams.
F. POPULATION DEMOGRAPHY AND BIOLOGY
1. POPULATION SIZE AND CONDITION: In the 0.8 km of streambanks and floodplains surveyed at Cinnamon Creek (003) , 86 plants were noted. These were vigorous individuals of unknown age. The number of plants found along the Gallatin River (004) was not
estimated. These, too, were vigorous individuals of unknown age.
2. REPRODUCTIVE BIOLOGY: Salix species may reproduce vegetatively via rooting of decumbent stems, or sexually by seeds. Although fruits were present on some plants, no seedlings were observed. Seedlings could easily have been overlooked, but the age structure of the population was characterized by at least 90% mature plants, with about 10% of these showing partial senescence. Occurrence of suitable sites for germination is ephemeral, and most likely varies from year to year; conditions in some years may result in little or no sexual reproduction.
G. LAND OWNERSHIP: Salix wolf ii var. wolf ii at the
Cinnamon Creek site (003) occurs wholly on Gallatin National Forest lands. It is probable that the species also occurs on private lands along the river. Along the Gallatin River near Snowflake Springs (004), it occurs on both Gallatin National Forest lands and State of Montana lands (Gallatin Wildlife Management Area) .
II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS
A. POPULATION CONDITION: Both documented populations of Salix wolf ii var. wolf ii appear to be stable at this time.
B. THREATS TO POPULATIONS: Threats to these two populations of Salix wolf ii var. wolfii appear to be minimal at this time. Horse pasturing immediately behind the Cinnamon Creek Ranger Station may cause some damage to individuals at that site, but is not likely to severely threaten the viability of the population.
C. RECOMMENDATIONS FOR FURTHER ASSESSMENT: It is likely that Salix wolfii var. wolfii occurs more extensively in the northern regions of the Gallatin National Forest and its extent should be assessed. Surveys should be conducted at the most likely time of fruiting (mid-June through July) , as the vestiture of the capsules is diagnostic of the variety.
D. SUMMARY: Salix wolfii var. wolfii is a southerly variety of the species which extends into southwest Montana. In the Gallatin National Forest it is documented from two sites, both in the Gallatin Canyon. Further surveys are likely to reveal that the variety occurs more extensively in the northern regions of the Gallatin National Forest.
