244 Bicknell : Studies in Sisyrinchium 



400 miles from east to west. Its white flowers make it easily 

 seen although it is seldom tall/' 



The following particulars may now supplement the original de- 

 scription of this plant (Bull. Torr. Club, 26: 452-3): 



Plant becoming 35 cm. high, sometimes merely glaucescent : 

 tufts often very close and narrow : primary bract sometimes 6 cm. 

 long and surpassing the inner one 35 mm. : flowers frequently 

 pure white : perianth 4-8 mm. long, column 3-4 mm. high : cap- 

 sules obovoid-oblong to subglobose, usually thin-walled and cor- 

 rugate : seeds very small, about .75 mm. in diameter, obovoid and 

 irregularly angled, black, finely rugulose, becoming smooth or 

 nearly so. 



Sisyrinchium Idahoense Bicknell 



British Columbia: Agassiz, May 8 and 14, 1889, full flower, 

 meadows, Macoun ; Lower Frazier River, 49 N. lat, Dr. Lyall, 

 1859; Vancouver Island, Victoria, June 10, 1893, full flower, 

 Macoun ; Nootka Sound, July, 1896, full flower, Jos. R. Anderson. 



"This is the common species west of the Coast Range in Brit- 

 ish Columbia and on Vancouver Island" [J. M.]. 



The specimens from Agassiz and the Lower Frazier River are 

 nearest to the Idaho type, but are more slender throughout, and 

 with the leaves and stems smooth-edged or nearly so. The speci- 

 mens from Nootka Sound are small and still more slender, ap- 

 pearing quite unlike the type, but they are imperfect and can be 

 referred at present only to a reduced northern form. The speci- 

 mens from Victoria are broader-leaved and more discolored be- 

 sides having the stem distinctly serrulate. They are closely 

 matched by certain specimens from western Washington and 

 Oregon which are doubtless not the same as 5. Idahoense, but 

 while these latter differ notably from typical 5. Idahoense in much 

 stouter roots, the roots of the Vancouver plant are equally slender 

 with those of the other British American specimens. 



5. Idahoense is almost certainly an aggregate, but the com- 

 ponent forms cannot be understood from present material. 



It is worthy of note that the Agassiz plant appears to be 

 earlier-flowering than the plant in Idaho, and also blooms de- 

 cidedly earlier than does 5. angustifolium anywhere in British 

 America.
