Recent Fern Literature 
Dr. Paul W. Graff: has listed five ferns as previously 
unreported from Montana—Ophioglossum vulgatum, Cys- 
topterrs fragilis, var. angustata, Aspidium cristatum, A. 
Filix-mas and A. spinulosum, var. intermedium. These 
reports are based on specimens in the herbarium of the 
University of Montana and are accompanied by notes 
on the species concerned and a comparative table of 
their ranges in the states and Canadian provinces adja- 
cent to Montana. 
Unfortunately, Dr. Graff has overlooked a good deal 
of literature on Montana ferns. Ophioglossum vulgatum 
which he lists as new to the state, was reported in 1917 
by Prof. M. J. Elrod as having been found at Yellow Bay, 
Flathead Lake (the same station cited by Dr. Graff) by 
Miss Bessie Green in 1914.2 Aspidiwm Fihax-mas, con- 
cerning which Dr. Graff says he has been unable to 
locate any definite report, was recorded by T. J. Fitz- 
patrick in 1904 from six Montana localities.*>—C. A. W.
