Abstract:
Every student of recent taxonomic systems, as illustrated in numerous floras, is aware of the manifold difficulties which beset the path of the Botanist who attempts to delimit and describe the specific characters of plants in such a way as to avoid confusion and uncertainty of diagnosis. It is partly owing to those difficulties that the methods of the morphologist have been extended to include a study of plant anatomy, which in some cases at least, has proved of definite value for purposes of identification and classification, and particularly so when used to supplement other (generally external) characters.
