The Genus Isoetes ; by Dr. George Engelmann.— This is a 

 pamphlet of 33 pages from the Transactions of the St. Louis 

 Academy, Vol. IV, No. 2, and was read in February of this year. 

 This insignificant genus was for a long time ignored by botanists 

 and until thirty or forty years ago, the few specimens that were col- 

 lected were referred to /. lacustris. Of course a genus that was at- 

 tractive to no one else was just the one for Dr. Engelmann to study 

 and the result is that we now wonder why so interesting a ge- 

 nus was not studied long ago. At least this pamphlet will spur us 

 all to activity and its author will begin to hear frequently of more 

 Isoetes. This paper is remarkable for its completness, containing 

 all the information pertaining to the genus that can be given at 

 the present time, though, to he sure, the literature of the subject 

 has not yet become very extensive. First the author gives the his- 

 tory of the genus in North America, giving a complete list of the 

 discoveries of the various species, from "that of Pursh in 1806 (?) to 

 that of the author and Mr. Pringle in 1881. Under the same head- 

 ing is included a list of publications in reference to the genus. 



Then follows an account of the morphology and biological 

 elements of the members of this genus, the simplest vascular plants
