In the notes appended to the list, I omitted to mention Lobelia, 



Kalmii, as an addition to the flora/* not being observed by any 

 other Provincial collector. 



The object of the foregoing list is no doubt that of presenting 

 an additional location for species already described, since all contain- 

 ed therein, with the exception of seventeen, will be found in the 

 catalogue appended to vol. iv., p. u., of our Transactions, 1875 and 

 1876. The major part of them have not been before credited to 

 Hants County, although the species in the present list from other 

 places appear in the catalogue under their respective localities. 

 Of the seventeen additional species denoted by italics, five are cul- 

 tivated exotics, and two are garden escapes, leaving twelve to be 

 accounted indigenous additions to the Provincial Flora. 



I may be excused for remarking here upon the concluding notes 

 of Prof. How's preface, viz., those furnished him by Mr. Thompson, 

 affording as they do, an example of error, to which all are liable 

 by generalizing from a narrow field of observation. In one place, 

 he remarks upon what seemed to him a total absence of Gaultheria, 

 procumbens, and of its substitution by chiogenes. Such a cir- 

 cumstance may be true of Scot's Bay, but it would be wrong 

 to imply that the same held good for the whole Province. A 

 reference to the published catalogue gives as localities, Hants, 

 Halifax, Guysborough. It is very plentiful in Halifax county, 

 and can be found within convenient distance from the city. It is 

 moreover more abundant than chiogenes, although yver often they 

 accompany each other. Likewise, he notices the absence of Rho- 

 dora Canadensis, scarcely excepting the Vaccinise, the most abun- 

 dant and wide-spread of our Heath worts. The failure was, no 

 doubt, owing to the season at which the locality was under observa- 

 tion. The Rhodora, it must be remembered, is an eaily bloom, 

 putting forth, previous to leafing. It is usually out of blossom by 

 the time that its leaves are fully expanded. It is rare to find a 

 specimen for the Herbarium with perfect flowers and leaves toge-
