Botany 705 



The systematic position of the five new genera, Enterobryus, 

 Eccrina, Arthromitus, Cladophytum, and Corynocladus, must 

 be said to be still in doubt, for during the last forty years 

 neither mycologists nor algologists have ventured to assign 

 them definitely to their proper order, nor have they been able 

 to add much to the account first given by Leidy. 



Of the less elaborate botanical publications we may mention 

 three papers on exotic floras: the "Flora of Alaska," published 

 in the Report for 1867, by Doctor J. T. Rothrock, who gave 

 an enumeration of the species, both of pha;nogams and cryp- 

 togams, collected by himself, as well as of those collected by 

 previous explorers; the "Flora of St. Croix and the Virgin 

 Islands," by Baron H. F. A. Eggers,^ being an enumeration 

 of phaenogams and higher cryptogams of that region, with 

 notes and introduction; and the "Botany of Bermuda," by 

 General Sir John Henry Lefroy, formerly Governor of Ber- 

 muda,^ a work similar in character to the preceding. A 

 "Guide to the Flora of Washington and Vicinity,"^ by Pro- 

 fessor Lester F. Ward, was also a museum publication. An 

 introduction, giving statistics and general character of the 

 local flora, was followed by a list of one thousand three hun- 

 dred and eighty-four species, excluding Thallophytes, to- 

 gether with a "Check-List" and "Descriptions for Collect- 

 ing and Preserving Plants," which were issued separately the 

 following year. 



Scattered through the annual Reports of the Institution 

 are several miscellaneous botanical papers which deserve no- 

 tice. The Report of 1859 contains a paper by Doctor J. G. 

 Cooper on the " Distribution of the Forests and Trees of 

 North America," prepared in connection with some meteoro- 

 logical observations in progress under the direction of the In- 



1 " Bulletin No. 13 of the United States National Museum," 1879. 



2 "Bulletin No. 25 of the United States National Museum," 1884. 



3 "Bulletin No. 22 of the United States National Museum," 18S1.
