must bear the name of Dryopteris" then all ferns with a dis- 

 tinctly reniform indusium, i. e., Nephrodium or Lastrea, are out- 

 side this genus and should not be saddled with a name which 

 does not belong to them and was never tenable when given as 

 now in this connection. 



Binding the "Bulletin." 



Correspondence with our subscribers has shown that nearly 

 all preserve their copies of The Fern Bulletin and that a large 

 number put them into permanent binding: at the end of each 

 year. For the convenience of those who intend to have their 

 copies bound, it may be stated that Messrs. Neumann Brothers, 

 of New York, make a spscialty of binding this journal and turn 

 out very handsome volumes. They have bound our own copies 

 in gray cloth with gold lettering on back and sides in a most 

 satisfactory manner. The great advantage in having the journal 

 bound by this firm is that no matter when bound, the volumes 

 will be alike in style and appearance. 



A neat and inexpensive method of binding for those who do 

 not care to patronize bookbinders, is by means of the "klips" 

 manufactured for that purpose. All that is needed to turn the 

 numbers into a serviceable volume in ten seconds, is a pair of 

 klips and a cover of manilla. The klips do not injure the maga- 

 zines in the least and while holding them securely, permits of 

 their being separated again as quickly if desired. The klips 

 cost five cents each, a pair of keys which will open any number 

 of klips costs ten cents and a sheet of manilla that will make 

 several covers can be purchased at any paper store for a few 

 cents. 



It will probably be found best to bind the first three volumes 

 in one, and make separate volumes of the rest. Those who 

 would economize in the cost of binding may find it convenient to 

 bird the first four volumes in one, the next two in one, and 

 make subsequent volumes the size of the latter. — Willard N.

Although all the species of Isoetes are perennial, only a small 

 portion of the plant persists from year to year. The roots, the 

 leaves and the bulky cortex are shed or decay annually, and are 

 as often renewed from the stem, apex and the meristematic zone 

 which surrounds the small central permanent cylinder. — R. W. 

 Smith in Botanical Gazette.
