It is difficult to frame an exact definition of this plant from 

 present material which, while fully attesting the distinctness of the 



fifoliuui 



camp 



fl 



tion while not permitting its solution. In appearance the plant is 



similar to S. angustifolium or, in its more slender forms, to S, 



ccimpestre but differs from both in its uniformly twin spathes and 



Irom the former in mostly white or pale bkie flowers and smaller 

 fruit. 



I he type locality for the species is West Kentucky and speci- 

 mens from this general region have been more particularly held in 

 View m the foregoing description. So far as specimens and notes 

 ^n labels indicate the plant is here uniformly white-flowered. 

 Specimens from prairies near Chicago have large very pale blue 

 owers and unusually long bracts, which on a f^w' of the plants 

 ^re obscurely scabrous on the sides, a feature shown only by one 

 other specimen of my series, also from Illinois. 



From Sewanee, Tenn., comes a specimen having apparently 

 ^'^ly small blue flowers and capsules but i mm. or less high. 

 The only specimen sccxx from Louisiana is vcxy pale in color and 

 has stout spathes with long, slenderly attenuate primary bracts ; 

 the apparently small flowers are white on somewhat slenderly ex* 

 serted pedicels. Specimens collected in Mississippi by Prof S. M. 

 Tracy are noteworthy from their large size and broad leaves and 

 stems, the former becoming 3.5 mm. wide; the spathes are un- 

 usually stout, the pale blue flowers seemingly of medium size. 

 Contrasting so markedly with these as to seem quite distinct yet 

 apparently connected by intermediate forms, are certain specimens
