Christ, H., C a n Scolopendrhim Lindeni Hook, be separated 



from S. vulgare Sm.? (The Fern Bulletin, Vol. XI. July 



1903. p. 86—87.) 



Exception is taken to the Statement made by William R. Maxon 

 in a paper entitled „On the Occurrence of the H a r t' s - tongue in 

 America» (Fernwort Papers, Linn. Fern Chapter, 1903) that Scolopen- 

 dtiiim Lindeni, described from Chiapas, Mexico, is a species „clearly 

 distinct" from S. vulgare. Recent specimens received from Chiapas 

 go to show that Hook er was justified in subsequently abandoning the 

 species, inasmuch as truly diagnostic characters warranting its Separation 

 de not exist. The slight differences observed are due to the unusual 

 habitat, are paralleled in certain specimens from Italy and do not 

 necessitate even varietal recognition.

Nephrodium nnitum, known previously in the United States 

 only from Florida, occurs in Texas. Lygodium palmatum is reported 

 from Pennsylvania. Mention of a „ternate Botrychium'-' from eastern 

 Texas. Note on a much-divided frond of Pteris aquilina affected by a 

 fungus which, it is suggested, may have brought about the „increased 

 division of the pinnules". Meniscium reticulatum from the everglades of 

 Florida is new to the United States flora.

XIV. (The Fern Bulletin. Vol. XI. July 1903. p. 73—75.) 



Deals with E. hiemale L., the typical form of which is European 

 and apparently does not occur in America. Most of the American 

 plants commonly referred to E. hiemale are of the category robustum 

 which can not be maintained as specifically distinct from hiemale and 

 may be known preferably as E. hiemale robustum. Ten „varieties" of 

 hiemale are recognized (viz. intermedium, Texanum, herbaceum, pumilum, 

 Suksdorfi, Drummondii, affine, robustum, Californicum and Doellii), and 

 a key for their determination is provided.
