320 HOW — NOVA SCOTIA PLANTS. 



ther. Those, who in early Spring observe the purpling of our road- 

 sides and field borders by its masses of bloom can never separate 

 it from our landscapes. In the catalogue it is denoted in all locali- 

 ties observed. Mitchella repens, also referred to, is by no means 

 scarce, as the catalogue shows, though truly less abundant than 

 Cornus Canadensis, an observation which obtains for those parts of 

 the New England States which I have visited. As for Juniperus 

 communis, the botanist who struggles through uncultivated pastures 

 or pine openings, etc., in quest of plants, is in this locality, (Hali- 

 fax), at least, unpleasantly reminded of its abundance. 



The interest attaching to Mr. Poole's list arises from the 

 presence there of two foreign species, both occurring in the British 

 Flora, but not before described as American, at least we fail to find 

 them in the books on American Botany. These are Lotus cornicu- 

 lata Ord. Leguminosae, and Cotyledon umbilicus, Ord. Crassulaceee. 

 We may conclude with safety that both are importations, derived 

 from Britain, like a host of others, which to all appearance are 

 indigenous; both orders supply us with many introduced plants 

 which have spread themselves either widely or in very few localities. 

 "We have in this locality (Halifax) Medicago, Vicia, etc., of the 

 Leguminous order, now spontaneous. Sedum, acre, and S. rho- 

 diola of the Crassulaceee in like circumstances. I noticed recently, 

 also, the occurrence Linaria vulgaris, in two places near Halifax, 

 viz., the termination of the Coburg Road, and a fallow field on 

 the Chebucto Road. 



We cannot attach too much importance to the separation of 

 our indigenous species from those which have been inh'oduced, 

 the latter are annually encroaching upon the former, and are in 

 many instances supplanting them, being aided by the increase of 

 our agricultural area, and the destruction of the forests. Our 

 efforts should be at the present time directed towards collecting and 

 recording the existence of native plants, leaving the others for 

 future effort. To me it seems as unscientific to include introduced 

 plants in our list of aboriginal species, as it would be to enumerate 

 our domestic animals as being members of our native fauna. I am 

 therefore, compelled to confess that the published catalogue to which
