Genus covers are often entered in so many handwritings that 

 their records are confusing, or at least trying. Uniform cards, 

 arranged alphabetically in a catalog, give ready reference by the 

 sequence number to the sequence itself in the proper family, 

 that number and genus name being readily seen and recognized 

 if the genus label is placed at the lower left hand corner. 



Figure 3 is presented with sample reprints of a legible and 

 durable catalog card and its genus cover slip duplicate. The 

 mere matter of the card being printed at the top, and the slip 

 being printed at the bottom, for more ready reference in their 

 respective places, is but a matter of slight ingenuity on the part 

 of any capable printer in adjusting two sets of guides on his 

 platen so that both sets may be printed without removing the 

 locked form from the press. The difference in thickness of 

 card and slip is, of course, obviated by the proper make-ready 

 on the platen. It often happens that herbaria, even those of a 

 private nature, specialize in some local range or limitation. The 

 ordinary hufi genus cover does not require any discussion. Local 

 species may be well distinguished from those of more general 

 range by placing them in a genus cover of dififerent color which 

 may be placed immediately above the regulation buff one. 

 "Red rope paper" is suggested as durable and suitable for such 

 local indication and will wear as well as the ordinary buff tag 

 board. 



The writer will be very glad, through the generosity of the 

 Central Museum of the Brooklyn Institute of Arts and Sciences, 

 to furnish sample copies of the family lists, and representative 

 genus cards and slips to those who have the intention of incor- 

 porating such a system for the more convenient use of their 

 herbaria.
