genera and species described and figured is as follows: pterido- 

 phytes — 22 genera, 64 species; gymnosperms — 8 genera, 13 

 species; dicotyledons — 405 genera, 987 species; and monocoty- 

 ledons — 119 genera, 504 species. In addition 16 pteridophytes, 

 1 gymno-sperm, 264 dicotyledons, and 68 monocotyledons 

 occurring in other parts of Quebec are mentioned. A 14-page 

 glossary, an explanation of the abbreviations of authors' names, 

 and a statistical table are included at the back of the book. 



The reviewer is particularly pleased to note that Marie- 

 Yictorin has accepted the most recent discoveries regarding the 

 identity of numerous eastern American plants formerly thought 

 to be conspecific with European forms, but now found to be dis- 

 tinct. The common bracken is thus Pteridium latiuscidiim (not 

 aquilinum), the lady-fern is Athyrium angustum (not Filix- 

 femina), the rock polypody is Polypodium virginianum (not 

 v id gar e), the broad-leaved enchanters-nightshade is Circaea 

 latifolia (not lutetiana) and the Canadian species is C. canadensis 

 (not intermedia) , the American liverleaf is Hepatica americana 

 (not triloba), the red-berried elder is Sambucus pubens (not 

 racemosa), the American cranberry-tree is Viburnum ameri- 

 canum* (not Opulus), etc. The use of Actaea pachypoda for our 

 common thick-pedicelled white baneberry (instead of A. alba) 

 and of Lycopodium fiabelliforme for our trailing Christmas- 

 green (instead of L. complanatum) are also in accordance with 

 most recent studies.

;: Marie- Yictorin is in error in his use of this binomial. Vi- 

 burnum americanum Mill., as Dr. Blake has shown, is synony- 

 mous with Hydrangea arborescens. The correct name for the 

 American cranberry-tree is Viburnum trilobum Marsh.
