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 .
