Allionia montanensis 



CiA??.oet- 



Perennial from a tuberous root: stems usually two or three, 

 slender, 5-7 dm. high, branching above, whitish below, glabrous 

 up to the branches of the inflorescence which are glandular pu- 

 bescent: leaves narrowly linear, 5-7 cm. long, tapering to both 

 ends, becoming smaller and bract-like at the nodes above: invo- 

 lucres numerous, 5 mm. high, usually 3-flowered, hirsute: flowers 

 bright purple: fruit obovate, 5-angled, but the ribs small, pubes- 

 cent with a fine and close pubescence, scarcely tubercled between 

 the ribs, 3 mm. long. 



Distinguished from Allionia linearis by the more slender 

 stem and leaves, smaller involucre, and especially by the smaller 

 less distinctly ribbed and tubercled fruit. Type specimens col- 

 lected in the canyon of the Thompson river, near the forks of 

 the river, Larimer county, Colorado, August 16, 1905, no. 3078. 

 Collected also in the canyon of the Cache La Pouder, near Home 

 Post Office, July, 1904.
