A Pbeliminaey List of the Botanical Expeditions in Ne- 

 BEiSKA, 1803-1893. 



BY FEEDEKICK E. CLEMENTS. 



The object of the subjoined list is to furnish easy and ready 

 reference to botanical field work done within Nebraska as now 

 bounded, and also to aid in the survey of the stat-i by showing 

 in what region work has already been done and by affording 

 some hint as to the nature and extent of this work, the disposition 

 of collections, etc. The present list does not pretend to com- 

 pleteness by any means. It simply purports to be a fairly full 

 and accurate resume of the present status of our knowledge on 

 this subject and is published partly for reasons given above and 

 partly in the hope of obtaining further information through out- 

 side channels. This preliminary list is intended merely to cata- 

 logue such botanical excursions as have assjimed the proportions 

 of expeditions and is in no degree a measure of all the field work 

 done in the state.
