556 FLORA OF McNAB's ISLAND, HALIFAX, N. S. — BARBOUR. 



contrivances, though prohably not in the same quantities as 

 might be obtained easier from elsewhere. 



The fungi of the island are very numerous and varied. 

 Seldom, if ever, have I seen, certainly not i'n colour, so many 

 Bas'idiomycetes and Gastromycetesj they are beautiful, too, in 

 many instances. 



Lichens also are abundant, but with neither of these 

 did I have much to do. AVhat notice I did take of the mush- 

 rooms will be referred to in my notes at the end of this paper. 



These few general observations are all I wish to offer on the 

 flora generally. I have looked at it from my own point of view^, 

 and though probably I have told you nothing new, possibly 

 I have suggested a new light in which to consider it. 



This brings me to Part II. of my subject, in which I deal 

 with work specially done in one or two orders. The results may 

 not appear large, but only a few plants can be dealt with care- 

 fully in a season. The work done is, as in a previous paper I 

 read before the Institute a couple of years ago, mainly on 

 variation. 



Part II. — Work in Special Orders. 

 PHmidacece. 



Trientalis Americana. Star flower. — One of your com- 

 monest spring flowers. 500 specimens at least examined, and 

 on that data results given. Variations in calyx and corolla 

 practically none. In a few specimens one sepal was normally 

 abse'nt. It was in the stamens the variations occurred. In 7Y 

 specimens I found 7 stamens in each ; in 167 specimens I found 

 8 stamens in each ; in 205 specimens I found 6 stamens in each ; 

 and this latter number seems to be the most usual number of 

 stamens present. In 17 specimens I found 5 stamens in each ; 

 in 34 specimens I found 4 stamens in each. It is curious to
