ferns to spring up in bottles in this way, even in regions 

 where no ferns have been growing. The bottles form 

 so many little wardian cases in which the ferns find 

 conditions very favorable for growth and seem to get 

 along very well without a change of air. The writer 

 of the article mentioned records a case in which a clear 

 glass jar closed air tight for eight years had neverthe- 

 less supported a growth of ferns. In size the jar was 

 but eight inches by three inches and neither water or 

 air had been admitted since it was first sealed up This 

 phenomenon has been seized upon as a means of 

 propagating ferns. It is reported that if small pieces 

 of the roots tock are placed in such jars with an inch or 

 so of clean moist sand in the bottom and then tightly 

 sealed up, the pieces of rootstock will in time evolve 

 new buds and roots and these will eventually become 

 sturdy little plants. The point at which rootstock and 

 stipe join, seems to be the region that most readily pro- 

 duces buds, but any living part of the rootstock may be 

 depended on to do so in time. 



New Stations for Florida Ferns. — In the "Fern 

 Flora of Florida" published in Volume XII of this 

 magazine, the range of the golden polypody {Poly- 

 podium aureum) was given as northward nearly to 

 St. Augustine. Its known range is now extended by 

 Mrs. M. W. Satchwell who has found it in several 

 pla'ces about Jacksonville a considerable distance 

 farther north. In the same country (Duval) she also 

 finds Botrychium obliqiium, Asplenium ebeneum and 

 Polystichium acrostichoides, plants which heretofore 

 were known only from the extreme north western part 

 of the state. Duval county is on the east coast and 

 some distance from the state line.
