A sixth may now be added: it was collected on July 26 by J. E. Benedict, Jr., and the writer one mile west of Harrison- burg, Rockingham County. Though not representing a new county, the following report may also be of interest. About 2 miles northeast of Staunton, U. S. Highway No. 11 forks, the left-hand branch avoiding traffic by entering only the outskirts of the town. Southwest from the filling station in the fork there extends a long series of limestone ledges with clayey depressions between, and here this fern is probably as abundant and accessible as anywhere in the northeastern part of its range. It grows in dense clay, mingled with the usual weeds of pastured land, and can best be found after a rainy spell. WooDsiA IN North Carolina.—The manuals give the range of Woodsia ilvensis as extending into this state, but no specimens appear to be preserved in any her- barium, so that this report must be considered as lacking adequate foundation. On the other hand, Woodsia sco- pulina (or its southeastern representative) is unquestion- ably represented by a specimen in the New York Bo- tanical Garden. This had been collected by the late J. A. Ferriss, supposedly on a cliff in the Craggy Moun- tains, in Buncombe County. Mr. William A. Knight, Mr. J. E. Benedict, Jr., and I recently spent a day in that region, exploring a number of cliffs, but were un- able to find any trace of it. As its reported occurrence on White Oak Mountain in Polk County has also never been rediscovered, the presence of any species other than W, ohtusa in North Carolina remains doubtful.
