Nelson : New Plants from Wyoming 267 



This strikingly caespitose species has no very near ally. It 

 seems to be nearest P. Macounii though it may in some ways be 

 compared with P. saximontana and P. Plattensis. From all of 

 these it differs in the shape of the petals and its denser pubescence ; 

 from the two former in the absence of all tomentum and in the 

 narrower leaf-segments ; from the latter (which has no whitish 

 pubescence) in the stouter, more branched and scaly caudex. 



It was plentiful on the high, open slopes among the sage- 

 brush, near Monida, Montana. Type no. 5414, June 16, 1899.

Annual, root slender, vertical : stem erect, 2—3 dm. high, sim- 

 ple or with two or more smaller, erect, accessory ones from the 

 crown : pubescence of two kinds — some scattering, hispid-ciliate 

 hairs and a fine puberulence, nearly glabrous upward : leaves nu- 

 merous, linear-oblanceolate, from entire to repandly toothed, the 

 radical slender petioled, 6-12 cm. long (including the petiole), the 

 stem leaves shorter and shortening upward : inflorescence leafy : 

 flowers axillary, at first crowded, becoming more open as the 

 stem lengthens : calyx lobes about equaling the tube, 2 cm. long, 

 shorter than the suborbicular, white petals : filaments very slender, 

 as long as the calyx lobes : capsules linear-clavate, spreading and 

 curved, 2—3 cm. long. 



This seems to be a very rare plant. Though twice collected, 

 both times on Wind River, in Fremont county, only single speci- 

 mens were secured — the first by Prof. B. C. Bufifum, August 2, 

 1892 ; the second by the writer in 1894, August 9, no. 779. 



Those specimens were named A. albicaulis (Pursh) Britt, but 

 their erect habit and nearly glabrous inflorescence show at once 

 that that cannot be. It may be worth while noting that the large 

 white petals dry the same color in herbarium specimens, but if left 

 to dry on the plant in the field they turn pink, as commonly oc- 

 curs in this genus, no matter how they are dried. 



This with one or two other species must all in a general way 

 be associated with A. albicaulis , but each shows characters in keep- 

 ing with the duration of the plant.
