A Graphic Guide to Ontario Mosses
by Robert Muma |
|
|
Foreword
|
|
This Guide is intended only as a graphic aid to PROBABLE GENUS, based on
recognizable growth forms of mosses. (The growth forms charted here do not
include all genera, and the growth form under which a genus is listed does not
always represent all species of that genus.) It is hoped that a study of
the Growth Form Plates will make it easier to use one of the recommended texts on mosses listed
in the Bibliography. For a systematic
listing of Ontario genera under class, sub-class, order and family, refer to
Ireland and Cain, CHECKLIST OF THE MOSSES OF ONTARIO.
If this Guide helps the beginner who is as yet unfamiliar
with moss terms, then it will have served its purpose.

Area Covered
|
|
Although
this Guide has been devised for Ontario mosses, like all life-forms, many of our
genera are found world-wide and are well distributed over eastern North America.
A few west coast genera have been included in the illustrations for wider
interest and broader definition.
