BOTRYCHIUM BITERNATUM UNDERW. 



By A. A. Eatox. 



Mr. W. C. Dukes of Mobile, Ala., in a small but very 

 interesting collection donated to the Fern Society her- 

 barium, includes specimens of this very rare species, col- 

 lected, ripe, in March, 1905. These beautiful plants are 

 very characteristic, possessing a very distinct individu- 

 ality, and convince me of the wisdom of Dr. Underwood 

 in referring them to a distinct species. In the same pack- 

 age Mr. Dukes sends a very odd form of B. tematum 

 obliqnuiu, the oddest I have yet seen, collected in October, 

 1904. It will thus be seen that the season of fruiting, as 

 pointed out by Dr. Underwood (Bot. Gaz. 22 : 408 ; Bull. 

 Torr. Bot. Club 25:529), is different from that of ter- 

 natum, even in the same habitat. It is to be hoped that 

 Mr. Dukes will be able to secure enough of this very 

 interesting species to supply the principal herbaria 

 with it.

COMPLETE SETS OF THE FERN BULLETIN. 



Three more complete sets of this magazine have come 

 to light, making a total of twenty known sets. It is not 

 likely that five more sets are in existence ; though there 

 are several nearly complete sets located. One of these 

 lacks a single number of one volume to be complete, but 

 though we have tried for nearly a year we have been 

 unable to complete it. If any reader has any numbers 

 prior to Volume VI. we shall be glad to offer cash for 

 them. It is something of a distinction to possess a com- 

 plete file of the magazine, inconsequential as the first 

 few volumes were. Those to be added to the list at 

 present are : Miss Harriet Wheeler, Chatham, N. Y. ; 

 Dr. C. B. Graves, New London, Conn., and Prof. W. G. 

 Farlow, Cambridge, Mass. If any others have complete 

 sets we would be glad to hear from them.
