its occurence in Texas gives rise to the suggestion that it may 

 yet be found in Alabama, Mississippi and Louisiana, near the 

 Gulf. Mr. Reverchon's specimens were found in the southeast- 

 ern part of his State. 



Lygodium paematum in Pennsylvania. — The climbing fern, 

 though found in Kentucky and Tennessee, keeps for the most 

 part to the Atlantic seaboard. Its occurrence very far inland is 

 always noteworthy, and I take pleasure in recording a station 

 for it in Eastern Pennsylvania, near Mauch Chunk, where it was 

 found last year by Mr. Daniel W. Hamm. 



The Range of the Ternate Botrychium. — The widely 

 distributed Boytrychium ternatum, whose ecological forms have 

 afforded the species-makers much employment in recent years, 

 seems to be quite rare in Texas. Mr. Reverchon has never 

 collected it, but in the American Botanist, for April, Mr. J. M. 

 Fetherolf reports it as occasionally seen during the winter in 

 Newton county, in Eastern Texas. The writer has seen no speci- 

 mens, but the fern is so different from any other, especially in 

 winter, when B. Virginianum is absent, that it is doubtless cor- 

 rectly identified. The species has been found in Louisiana and 

 is likely to occur in various places in Eastern Texas, where the 

 soil and climate are similar. Dr. Underwood has recently de- 

 scribed a southern form as B. tenuifolium, basing it upon speci- 

 mens from Louisiana, Elorida, Alabama and Missouri, and to 

 this the Texas specimens are doubtless to be referred. 



A. Pteris freak. — Mrs. A. T. Perry has recently sent me 

 pinnae from a frond of Pteris aquilina, which is curiously divided 

 and subdivided until it is several times pinnate. This form is 

 not infrequently met with where Pteris is common, but what 

 makes J:he present specimens interesting, is the fact that the 

 under surface is covered with a fungus that forms narrow, black 

 parallel lines, which might be easily mistaken for the fruiting 

 parts of an asplenium. This fungus is known as Dothidea Hli- 

 cina, and it would be interesting to know if its presence on the 

 frond is responsible for the increased division of the pinnules..
