Bickxell: Studies ix Sisyrixchium 837 



The more eastern plant must, of course, be taken as topical of 

 the species. It ranges from Newfoundland and Quebec south to 



J 



Specimens from 



this general region show more or less discoloration from drying, 

 but not nearly to the same extent as in 5. gmminoidcs. Si)eci- 

 . mens from Ontario to Saskatchewan and Colorado show little 

 change of color on the herbarium sheet and differ further from the 

 more eastern plant in being more glaucous and stiffcr with leaves 

 of rather thicker texture. Several specimens from Britrsh America 



M 



are unusually slender and apparently small-flowered. Others from 

 Minnesota are unusually stout and glaucous, and with some uni- 

 formity have the spathes brightly colored with red-purple quite in 

 contrast with anything seen from elsewhere, although the eastern 

 plant sometimes has the spathes tinged with dull purple. Still 

 other specimens from Minnesota are tall and slender and apparently 

 scarcely glaucous, the spathes long and narrow, the flowers on very 

 slender pedicels and with delicately membranous perianth. 



Several collections from Nebraska, well illustrated by Ryd- 

 terg's no. ^y^ from Banner Co. and no. 125 1, *' Flora of the Sand 

 Hills," are noteworthy by reason of stout central stem with rela- 

 tively narrow and smooth-edged wing-margins, rather long pedicels 

 ^nd subglobose, corrugated capsules. Several of these specimens 

 ^re branched. I have little doubt that this plant is entitled to a 

 ■distinctive name. 



Specimens collected in Newfoundland by Dr.. Robinson and 



are very small throughout with thin broadly winged 



M 



stem and thin leaves, the capsules only 2 mm. high or less and on 

 somewhat spreading pedicels ; these specimens show quite as much 

 discoloration as S. graminoides. Specimens from Alt. Desert 

 Island, Mahie, collected by Rand and Redfield are well developed 

 examples of the usual eastern plant, and New Brunswick and Prince 

 •fc-dward Island specimens are similar. 



The species comes into flower in most sections of its range from 



the 



May till the middle of J 



tions. In the neighborhood of New York flowering is sometimes 



2cond week of Tune. As far east as Newfoundland 



the flowerino- 



J 



August, as shown by the collections of Waghorne and Robinson 

 »nd Schrenk.
