PHOTOGRAPHS 33 SUMMARY Phlox kelseyi var. missoulensis is endemic to a limited portion of central and western Montana. It is currently known from eight locations ranging from Missoula to the Little Belt Mountains. The plant is on the Watch List for Region 1 of the U.S. Forest Service, and is categorized as 3C under the Endangered Species Act. The var. missoulensis is differentiated from the typical variety (var. kelseyi) , which also occurs in central and western Montana, by its more rigid stems and by growing on dry, gravelly slopes and ridge crests. Phlox kelseyi var. kelseyi has more or less succulent stems and occurs in moist, alkaline meadows. There is some controversy about the taxonomic status of var. missoulensis, and additional studies are needed. Phlox kelseyi var. missoulensis occurs over a wide altitudinal range, predominantly at 3600-6900 feet (1090-2100 m) . Flowering occurs from May through July, and pollination is likely by noctuid moths. Populations are generally between a few tens of plants to several thousand. Seven populations of Phlox kelseyi var. missoulensis occur on Forest Service lands; Deerlodge (2), Helena (2), and Lewis and Clark (3) National Forests. The other three are on privately owned land. Grazing by domestic livestock is not known to pose any current threat to local populations, although trampling could affect smaller populations in particular. The population at Waterworks Hill was threatened in the past by urban development, but this is not a current threat. Management planning should take all Montana sites into consideration in order to maintain viable populations on U.S. Forest Service, Region 1 lands. Field surveys should be continued in areas of suitable habitat for new populations. Additional studies are needed on the systematics of Phlox kelseyi var. missoulensis, its variation, and relation to other Phlox taxa in the area. 11 I. SPECIES INFORMATION A. CLASSIFICATION 1. SCIENTIFIC NAME: Phlox kelsevi Britton var. missoulensis (Wherry) Cronquist. 2. COMMON NAME: Missoula phlox. 3. FAMILY: Polemoniaceae (Phlox Family). 4. GENUS: The genus Phlox occurs in North America and northern Asia, and contains about 60 species (Hitchcock et al. 1959) . In Montana, there are 11 native species (Dorn 1984). 5. SPECIES: Phlox kelseyi var. missoulensis is endemic to western and central Montana and is currently known from Missoula, Granite, Powell, Lewis and Clark, Cascade, Judith Basin, Beaverhead, and Meagher counties. The variety missoulensis was originally described as a distinct species in 1944 (Wherry 1944) , and was reduced to a variety of P. kelseyi in 1959 (Hitchcock et al. 1959) . The species also contains the typical variety, var. kelsevi . which occurs from western and central Montana, to central Colorado and south- central Idaho. Some authors recognize var. salina. which occurs in northeastern Nevada (Cronquist et al. 1984) . The var. kelseyi is more or less succulent, and occurs in moist, alkaline meadows, while var. missoulensis is stiffer and generally grows on drier, open slopes. There is some question about the taxonomic status of var. missoulensis. Cronquist (Hitchcock et al. 1959) reduced Phlox missoulensis Wherry to a variety of Phlox kelseyi. Wherry (1966) disagreed with this, maintaining that "they differ completely in indument and in numerous morphologic details." Wherry further suggested that P. missoulensis was closer to P. douqlasii (now known as P. caespitosa) and that if any reduction were required it should be as a variety of P. douqlasii. Also, small-leaved plants of Phlox kelsevi var. missoulensis come close to larger- leaved specimens of P. pulvinata . and can be hard to distinguish. In a more recent, unfinished study of Phlox kelseyi. Campbell (1991) concluded that Phlox kelseyi var. missoulensis is a valid taxon and that it "comprises a few sensitive. isolated populations that occur only in western Montana. " A number of specimens documenting sites were annotated by Lisa Campbell during her work on the species as a graduate student at the University of Montana; her study was never completed. Specimens collected during the 1990 field season that document locations contained in this report, were sent for identification to Dr. Dieter Wilken, a specialist in the family Polemoniaceae (Phlox Family) . He reviewed the specimens, but did not feel he had enough knowledge of this complex of species to annotate the specimens. It was his feeling that a full systematic study was needed for the genus Phlox. Until a more informed opinion can be had, the specimens and the sites will remain as currently labeled. B. PRESENT LEGAL OR OTHER FORMAL STATUS 1. FEDERAL STATUS: Phlox kelseyi var. missoulensis is on the Watch List for Region 1 of the U.S. Forest Service. Under the Endangered Species Act, administered by the U.S. Fish and Wildlife Service, it is categorized as 3C ("taxa that have proven to be more abundant or widespread than was previously believed, and/or those that are not subject to any identifiable threat"). 2. STATE: Phlox kelseyi var. missoulensis has most recently been ranked by the Montana Natural Heritage Program (Shelly 1990) as an S2 species ("imperiled in Montana because of rarity", 6-20 occurrences) . C. DESCRIPTION 1. GENERAL NON-TECHNICAL DESCRIPTION: Phlox kelseyi var. missoulensis is a small perennial plant up to 4 inches tall, with stems that grow in a crowded tuft from a taproot. The leaves are linear to linear-lanceolate, usually 0.4-1.0 inch long or a bit shorter, and 0.04-0.10 inch wide near the middle. The leaf surfaces vary from hairless to spreading hairy, and sometimes have small glands. The leaf margins are thickened but not whitish, and are hairy, at least towards the base. The inflorescences contain 1-5, light blue to white flowers, which are solitary at the branch ends. The flower tube is 0.4-0.5 inch long, as long or longer than the calyx. The calyx is 0.3-0.4 inch long, with the tissue between the ribs flattened. The styles of the pistil are 0.16-0.30 inch long. TECHNICAL DESCRIPTION: Plant a caespitose, taprooted perennial with numerous stems up to 1 dm tall, closely crowded and suberect, glabrous to spreading-hirsute and sometimes glandular; leaves linear to linear-lanceolate with a subacerose tip, mostly 1-2.5 cm long, or some a little shorter, 1- 2.5 mm wide near the middle, surfaces glabrous to hairy or glandular, the margins thickened but not whitish, ciliate at least toward the base; inflorescence 1-5 flowered; flowers short- pedicellate (2-8 mm) or sessile, solitary at the end of the stems; sepals 7-11 mm, united 3/8 to 1/2 their length, cuspidate, lobes flattened with prominent or inconspicuous midrib, intercostal membranes flattened; corolla light blue to white, tube 10-13 mm long equalling or exceeding the calyx, lobes 6-9 mm; styles 4-7.5 mm (adapted from Hitchcock et al. 1959, Booth and Wright 1966, and Wherry 1955) . LOCAL FIELD CHARACTERS: Phlox kelsevi var. missoulensis is distinguished from the typical variety Phlox kelseyi var. kelseyi by its more rigid stems, and by growing on dry, open slopes while var. kelseyi has more or less succulent stems and occurs in moist, alkaline meadows. Small-leaved plants of Phlox kelseyi var. missoulensis may be hard to distinguish from larger-leaved specimens of P. pulvinata, since there can be overlap between P. pulvinata vs. P. kelseyi var. missoulensis in style length (2-5 mm vs. 4-7.5 mm) and leaf length (0.5-1.2 but occasionally to 1.5 cm vs. 1-2.5 cm). Current identification keys are in Hitchcock et al. (1959) and Dorn (1984) . Photographs (pp. 33-37) illustrate the flower, habit and habitat of P. kelseyi var. missoulensis. GEOGRAPHICAL DISTRIBUTION 1. RANGE: Phlox kelseyi var. missoulensis occurs only in Montana and ranges from Waterworks Hill in Missoula to the Little Belt Mountains. 2. CURRENT SITES: Phlox kelseyi var. missoulensis is currently known from ten locations in Montana, 7 west of the Continental Divide, and three in Little Belt Mountains of central Montana, Fig. 1, p. 5. Details of each occurrence and exact locations as mapped on U.S.G.S. topographic maps are in Section IV, element occurrence print-outs and maps pp. 12-22. 3. HISTORICAL SITES: None. 4. UNVERIFIED/UNDOCUMENTED SITES: None. 5. AREAS SURVEYED BUT SPECIES NOT LOCATED: The survey emphasized relocating and mapping known locations, although several new areas were searched without result. The following areas in Cascade County were searched in 1990, but Phlox kelseyi var. missoulensis was not located at these sites: portions of T14N R7E, Section 3, SW4 (Keegan Peak), and Section 15, NE4 (Belt Park Butte) . E. HABITAT: Phlox kelseyi var. missoulensis occurs in habitats that range from sparsely vegetated with dry gravelly slopes, to heavily vegetated forb meadow sites. Most sites are on windswept ridge crests on all aspects. 1. ASSOCIATED VEGETATION: Phlox kelsevi var. missoulensis populations occur in sparse grassland and forb communities ranging from dry gravelly slopes and heavily grazed pastures, to higher elevation krummholz communities. Associated native species include: Achillea millefolium (yarrow) Aqropyron spicatum (bluebunch wheatgrass) Allium cernuum (nodding onion) Anemone cylindrica (long-headed anemone) Antennaria umbrinella (umber pussytoes) Arenaria conqesta (ballhead sandwort) Aster scopulorum (crag aster) Astragalus vexillif lexus (bent-flowered milkvetch) Besseya wyomingensis (Wyoming besseya) Cerastium arvense (field chickweed Chrysopsis villosa (hairy golden-aster) Claytonia lanceolata var. flava (yellow springbeauty) Cryptantha celosioides (cockscomb cryptantha) Delphinium bicolor (little larkspur) Dodecatheon pulchellum (few-flowered shooting star) f£ J3 U 3) Doualasia montana (Rocky Mountain douglasia) Eriaeron compositus (cut-leaved daisy) Erioaonum flavum (yellow buckwheat) Erioaonum ovalifolium (oval-leaved eriogonum) Festuca idahoensis (Idaho fescue) Festuca scabrella (rough fescue) Geum triflorum (old man's whiskers) Gilia spicata (spicate gilia) T,esauerella pavsonii (Payson's bladderpod) Lewisia rediviva (bitterroot) Linuin perenne (blue flax) Lomatium cous (Cous biscuit-root) Microseris niarescens (black-hairy microseris) Oxvtropis sericea (silky crazyweed) Penstemon eriantherus (fuzzytongue penstemon) Penstemon procerus (small-flowered penstemon) Phlox pulvinata (cushion phlox) Poa secunda (Sandberg's bluegrass) Polygonum bistortoides (American bistort) Potentilla diversifolia (diverse-leaved cinguefoil) Sedum stenopetalum (wormleaf stonecrop) Selaainella densa (compact selaginella) Senecio canus (wooly groundsel) Townsendia parrvi (Parry's townsendia) TOPOGRAPHY: Phlox kelsevi var. missoulensis occurs over a wide altitudinal range, predominantly from 3600-6900 feet (1090-2100 m) in elevation, with the highest site at 7540 feet (2290 m) . It occurs commonly on slopes and ridge crests, with various aspects. SOIL RELATIONSHIPS: The soils under Phlox kelseyi var. missoulensis populations are developed on a wide variety of parent materials. Several populations (Emerine Gulch (001) and Kings Hill (006)) occur in calcareous soils. Site-specific soil information is not available for each known location. However, the sites are usually rocky or gravelly, and moist to dry, with weakly developed soils, probably Entisols in most cases. REGIONAL CLIMATE: The regional climate within the range of Phlox kelsevi var. missoulensis in western and central Montana is characterized by hot, dry summers and cold, snowy winters. The precipitation peak is generally as rain in May and June (U.S. Department of Commerce 1982). The climatic station closest to the central Montana sites is at Stanford, which at 4710 feet (1435 m) is 1000-2000 feet (300-600 m) lower than most of the sites in the Little Belt Mountains. For the period 1951-1980 (U.S. Department of Commerce 1982) , the January mean temperature was 20.5°F (-6.4°C), the July mean temperature was 65.2°F (18.6°C), and the annual mean temperature was 44.2°F (6.8°C). The mean annual precipitation was 15.34 inches (38.9 cm), with May (3.01 in) (7.6 cm) and June (3.07 in) (7.8 cm) being the wettest months. The Missoula climatic station is at 3190 feet (972 m) , about 400 feet (120 m) lower than the Waterworks Hill site, which is the lowest known occurrence of Phlox kelseyi var. missoulensis . For the period 1951-1980 (U.S. Department of Commerce 1982), the January mean temperature was 21.3°F (-5.9°C), the July mean temperature was 67.2°F (19.7°C), and the annual mean temperature was 44.1°F (6.7°C). The mean annual precipitation was 13.29 inches (33.7 cm), with May (1.62 in) (4.1 cm) and June (1.85 in) (4.7 cm) being the wettest months. F. POPULATION DEMOGRAPHY AND BIOLOGY 1. PHENOLOGY: Flowering generally occurs from May through July, with earlier flowering dates at lower elevation sites. 2. POPULATION SIZE AND CONDITION: Population sizes range from a few plants to 10,000 plants. 3. REPRODUCTIVE BIOLOGY a. TYPE OF REPRODUCTION: The flowers of Phlox kelseyi var. missoulensis are perfect, and probably protandrous and cross-fertilizing, since most Phlox species are (Grant and Grant 1965). Campbell (1991) felt this slow growing perennial had a low recruitment rate. b. POLLINATION BIOLOGY: Pollination mechanisms have not been studied for Phlox kelseyi var. missoulensis. However, its pollination biology can be inferred from information on other similar Phlox species. The corolla is salverform and the stamens are inserted at different levels in the corolla tube. The stigma and anthers are well within the corolla tube, and the corolla tube is 1.0-1.3 cm long. These characteristics are consistent with tongue-tip pollination involving noctuid moths (Grant and Grant 1965) . SEED DISPERSAL AND BIOLOGY: Each flower produces a capsule with three locules, and generally 1 (2-4) seeds per locule. The seeds do not become mucilaginous when moistened as in some other genera of the Phlox Family. Thus, there appear to be no special adaptations for seed dispersal and nothing is known of the seed biology. POPULATION ECOLOGY 1. BIOLOGICAL INTERACTIONS COMPETITION: No studies have been done on competitive interactions, either intraspecif ic or interspecific. However, the frequent occurrence of Phlox kelseyi var. missoulensis in open, unshaded areas suggests that it is not very tolerant of competition from other plants, especially for light, and would not do well in communities with overtopping vegetation. LAND OWNERSHIP Seven of the ten occurrences of Phlox kelseyi var. missoulensis in Montana are on land managed by the U.S. Forest Service. The other three occurrences are on privately owned land. Specific information for each occurrence is given below and exact locations are listed in Section IV, pp. 12-22. a. U.S.D.A. Forest Service Deerlodge N.F.

Privately Owned Manley Ranch (008) Rough Fescue Ridge (003) Waterworks Hill (002) II. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS A. THREATS TO CURRENTLY KNOWN POPULATIONS 1. GRAZING: Grazing by domestic livestock is not known to pose any current threat to Phlox kelseyi var. missoulensis populations. The plants themselves are likely unpalatable because of their woodiness and hard, pointed leaves. However, trampling associated with heavy grazing could affect this species. 2. URBAN DEVELOPMENT: The population at Waterworks Hill (002) was threatened by an urban development proposal in the recent past, but this is not a threat currently. B. MANAGEMENT PRACTICES AND RESPONSE: No information is available on responses to specific management actions. However, Phlox kelseyi var. missoulensis seems to be able to occupy disturbed sites such as old roads (004) and heavily grazed pastures (008) . C. RECOMMENDATIONS FOR MAINTAINING VIABLE POPULATIONS: The following recommendations are made to ensure that the long-term viability of Phlox kelseyi var. 10 missoulensis populations is maintained on U.S. Forest Service land in Montana. 1. Protection of natural habitats that currently support Phlox kelseyi var. missoulensis populations. Management plans on the Lewis and Clark National Forest and the Helena National Forest should take all known populations into consideration and prevent disturbance of the sites. 2 . Notification of U.S. Forest Service personnel of sites on U.S. Forest Service lands. To prevent inadvertent impacts on currently known sites, personnel involved in planning activities should be provided with detailed information on the locations of Phlox kelseyi var. missoulensis populations. It is especially important that timber sale managers, engineers, and range conservationists at the Ranger District level know these locations so that disturbance can be prevented. D. RECOMMENDATIONS FOR FURTHER ASSESSMENT 1. Further field surveys of potential habitats. Additional field surveys should be made in central Montana to locate and delineate populations of Phlox kelseyi var. missoulensis. 2 . Establishment of monitoring studies to assess population condition and status. Monitoring studies should be established at several locations to better determine population dynamics and the effects of habitat modification on Phlox kelseyi var. missoulensis. The methods outlined in Lesica (1987) are suitable for monitoring some aspects of these populations and can be combined with other techniques such as ECODATA plots. 3. Further systematic studies: Additional studies are needed on the systematics of Phlox kelseyi var. missoulensis. its variation and its relationship to other Phlox taxa in the area. Specimens collected in 1990 will be sent to Dr. Arthur Cronquist (New York Botanical Garden) for review. 11 III. LITERATURE CITED Booth, W.E. and J.C. Wright. 1966. Flora of Montana, part II.
