88 BOTANICAL GAZETTE | FEBRUARY 
It continues to increase rapidly in size and value and, as in the 
library, efforts will be made to supply as full an illustrative 
series of plants as possible, for whatever special research may be 
taken up. 
Greenhouses and garden—The plant house (20 40 feet) is 
inadequate at present but suffices for the maintenance of some 
300 species of plants that are used in morphological work. 
Besides its further function as an adjunct to the laboratory of 
plant physiology, its principal use is as a depot for native plants 
freshly taken from their stations. There is no garden. 
Publication.— Minnesota Botanical Studies, a quarterly or occa- 
sional series of papers, offers a medium of publication for the 
researches of the department. Plates are provided as needed 
and separates are struck off when requested. 
Remarks.—I1n morphology and ecology the university offers 
to a limited number of graduate students every facility desired 
in the way of instruments, reagents, literature and material. 
There are accommodations at present for twenty. Problems in 
cytology, in embryology, and in anatomy are particularly kept 
in mind by the instructor. Special laboratories, three in number, 
are at the disposal of graduates in these lines. Collecting trips 
to different parts of the state can be arranged; cameras are pro- 
vided for ecologic work, and camping outfits are furnished those 
who desire to spend some time in the field. 
The department is prepared to assist in the taxonomic revision 
of any North American genus or family, and either has or will 
procure a full set of material for study. An exchange bureau is . 
maintained in connection with the herbarium, through the corre- 
spondence of which a large number of American collectors can 
be reached.
