NEW SPECIES, ETC., ISSUED IN THE PHYCOTHECA 

 BOREALI-AMERICANA. [ 



F. S. Collins.. 



The first fascicle of the Phycotheca Boreali-Americana, by Collin.s, 

 Holden & Setchell, was issued in February, 1895. Between that date 

 and the present time the writer has distributed in that work a number 

 of new species, varieties, and forms; in some cases the MS. name was 

 given in the label, with an indication of where the description would 

 be published; in other cases a regular description was printed in the 

 label. Several of these descriptions have since appeared elsewhere 

 in papers or notes, but in most cases the new species or variety has not 

 been published elsewhere. While no rules as to the nomenclature of 

 thallophytes were adopted at the recent Vienna Congress, it is probable 

 that when action is taken in regard to such plants, the rules governing 

 the higher plants will be adopted, unless special reason appear for 

 variation; and as the issuing of a new flowering plant in a set of 

 exsiccatae, with or without description, is not now a valid publication, 

 the position of an alga so issued is certainly precarious. To j^revent 

 possible future complications, the descriptions in question are here
