This first real flora of the province (previous treatments were merely catalogs, weed bulletins, etc.) is intended to “serve the needs’ of those who want to know what wild plants are present that may serve as hosts to fungus or insect diseases of crop plants, or what noxious weeds are present that should be stamped out. At the same time, a survey of the plants serves the broader interests of plant geographers who wish to know what species occur and how far agriculture has modified the natural flora.”
