Beihefte zum Botanischen Centralblatt, Vol. 22 Buchkatalog

Excerpt from Beihefte zum Botanischen Centralblatt, Vol. 22: Original-Arbeiten, Zweite Abteilung, Systematik, Pflanzengeographie, Angewandte Botanik Etc. Heft 1, 1. Juni 1907The present enumeration of Cu-rices is based upon some very extensive collections from Alaska, Yukon, British Columbia, Wa shington, Idaho and Oregon, made by Messrs. Wm. C. Cusick, Walter H. Evans, L. F. Henderson, C. V. Piper and Wm. N. Suksdorf the writer has, also, had access to the herbaria of the Canadian Geological Survey and of the U. S. National Museum. For the liberal loan of these collections and for the numerous specimens, that have been kindly donated to the writer, we wish to express our sincerest gratitude.As stated in a previously published paper, it is our intention to discuss the geographical distribution of these species within the area given, and throughout the northern hemisphere: the arctic regions and the mountaineous districts farther South. W hile thus offering these data in regard to the geographical distribution, we have thought that the enumeration might be of some interest to students of plantgeography, as a record of all the species that have been found growing within this area, from which will be seen the predominance of certain "gfcges, the total absence of others, and finally the association of allied types with apparently local and somewhat isolated species.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
