Book excerpt: Excerpt from Contributions to Canadian Botany This set of keys to Canadian and Newfoundland species of the important genus Solidago is compiled for the use of students; therefore explanation as to how to employ it is, probably, unnecessary. It is suggested, however, that there may be some which have little or no experience in the use of botanical keys, to whom an example of tracing to species may be helpful. The general key has been separated into provincial keys with a view to making the tracing-out easier, especially for elementary students. Any technical terms, that may not be understood, are explained in the glossaries of the current manuals by Gray, Britton Brown, Rydberg, etc. Students must carefully bear in mind that specimens of this difficult and complicated group of plants need to be studied critically and with infinite patience. There are, indeed, few keys considered by all to be without error, and which are capable of dealing with every exceptional form, also hybrids. The most advanced students and highest authorities will admit that they, on occasions, have erred in their determinations and in the construction of keys. Needless to say any constructive suggestions concerning these keys will be most welcome. A large proportion of the species, dealt with in this work, are represented in the herbarium, and as growing plants at the Central Experimental Farm, Ottawa. These specimens are available, at any time, for study. Donations of either pressed specimens or live plants will be most acceptable, especially, of course, such which may constitute an addition or new record.
