62 MINNESOTA STUDIES IN PLANT SCIENCE 



A study of a great deal of material at hand has failed to disclose any 

 appreciable differences in the characters of those organs which are usually 

 regarded as showing the greatest constancy, namely fruit and seed. For 

 this reason all the various segregates which have been made are herein 

 regarded as one species. And the specific name ferruginea of Graham is 

 adopted, since it antedates others. The specific name Brunoniana, as used 

 by some writers, appears invalid, having a previous application to a species 

 of the section Trachyphyllum. 



Those forms which exhibit constant peculiarities of form and habit, 

 correlated with a continuous range over a particular region, may be regarded 

 as varieties, and, as regards our species, at least two such varieties occur 

 continuously at the northern and the southern extremes of the range, with 

 a probable third in Washington and Oregon in the southern extreme. More 

 extensive collections and a more careful survey of the particular regions 

 are to be desired. A description of the varieties together with their ranges 

 follows : 



Var. foliacea var. nov. Scapus aut solitarius aut caespitosus tenuis 

 ample ramosus grosse atque laxe glanduloso-pubescens ad medium bracteas 

 foliaceas gerens, foliis magnis ad basim cuneatis grosse serrato-dentatis. 



Scapes solitary or tufted, erect or assurgent, commonly weak, coarsely 

 and loosely glandular-pubescent, often prolifically branched, with large leafy 

 bracts to above the middle, and numerous bulblets and flowers, the flowers 

 usually terminal. Leaves large, thin, broadly oblanceolate-elliptic, rounded 

 at the apex, coarsely serrate-dentate, the teeth few, cuneately narrowed 

 below into a broad or narrow base; glabrous or sparingly pubescent, con- 

 spicuously ciliate on the margins. The large leafy bracts and weak habit of 

 the plant are characteristic. 



Distribution. — High mountains of Kootenai County, and probably also Soshone 

 County, Idaho,

Var. grandiflora var. nov. Foliis ad 6 cm. longis ad basim cuneato-

 inflorescentiae ramis diffusis. 



Flowers unusually large, sometimes numerous ; bulblets few. Scapes 

 rather stout, solitary or several together, coarsely and loosely pubescent.
