bution seems to be largely montane. To find it in Louisi- 

 ana at less than 200 feet elevation is indeed surprising. 

 However, in common with Adiantum pedatnm L. and 

 other plants of the same district it may be looked for in 

 the hilly country of Western Mississippi to Vicksburg and 

 beyond — doubtless the break in its distribution is actually 

 much less than would at first appear.

A belated Maidenhair 



L. S. HOPKINS 



On last Thanksgiving morning (Nov. 28, 1912) while 

 looking for late specimens of Botrychia at Cheswiek, Alle- 

 gheny Co., Pa., a small but vigorous plant of the common 

 maidenhair (Adiantum pedatnm L.) was found. As it is 

 unusual to find the maidenhair at this season, it seems 

 advisable to make a brief record of its occurrence. 



The plant which was seemingly a young one bore eleven 

 fronds ranging in size from small to medium. All of 

 the fronds were green when collected, but two became 

 somewhat brown in the process of drying. None bore 

 fruit. 



The records of the local weather bureau show that th< 

 freezing point or lower was reached nine times during 

 November as follows: on the 2d. 3d, and 15th, 32°; on 

 the 16th, 31°: on the 24th and 25th, 28°: on the 26th, 31°;
