Mackenzie River : Fort Wrigley, July 20, 1892, first flowers, 

 Miss E. Taylor ; the most northern point from which any species 

 of the genus has been reported. Prof. Macoun writes : " Fort 

 Wrigley is a new location, about half way between Fort Simpson 

 and Fort Norman, on the right bank of the Mackenzie River, about 

 latitude 63 °." 



Sisyrinchium albidum Raf. 



This species must be admitted to the Canadian flora on the 

 evidence of a single collection made at Sandwich, Ontario, by 

 William Boott as far back as May 26, 1887. The specimens 

 (Gray Herbarium) are in full bloom, thus showing the plant to be 

 the earliest flowering of the British American species. The flowers 

 are pale blue, as in most Michigan examples. Since the species 

 is rather common in parts of southern Michigan, it is not surprising 

 to find that it crosses the Detroit River into Ontario. 



I have seen but a single specimen of this species from farther 

 east — Stanley county, North Carolina (W. W. Ashe). Very 

 possibly it may extend farther north and east in Ontario, 



Sisyrinchium mucronatum Michx. 



Like S. albidum this species crosses the Detroit River into 

 Ontario, having been collected at Sarnia, Lambton county, by Mr. 

 C. K. Dodge in June, 1897. Specimens from farther north in the 

 Province, Wingham, Huron county, have been distributed by Mr. 

 J. A. Morton, collected in full flower June 5, 1895. Most speci- 

 mens of this collection are much reduced and have very small pale 



green spathes and but little exserted pedicels only 10-15 mm. long. 



Mr. Dodge's specimens from Lambton county, have the spathes 

 deep purple and are closely matched by examples from east 

 Pennsylvania. 



A material and most unexpected extension of the known range 

 of the plant is afforded through a collection made at Prince Albert, 

 Saskatchewan, by Professor Macoun, June 29, 1896. The sped-
