TORREY BOTANICAL CLUB. 
_ A Revision of the North American Species of Ophioglossum, 
(PLATES 318-319.) 
By ELizABETH G. BRITTON. 
The Fourth of July excursion of the Torrey Botanical Club in 
company with the Philadelphia Botanical Club and the Washing- 
ton botanists, took place at Wildwood, New Jersey, a flourishing 
seaside colony about 12 miles from Cape May. On the afternoon 
of the 3d, Mr. Joseph Crawford, in company with Mr. Pollard, and 
Dr. Valery Havard, founda patch of Ophioglossum, between Holly 
Beach and Wildwood, growing in open woods under holly and 
oak trees (Q. nana and Q. falcata), in sandy soil where the grass 
had been cut. This single colony was the only one found in the 
region, and contained hundreds of plants, all in mature condition 
and beginning to turn yellow, thus making the patch a conspicu- 
Ous object, All of us who had seen O. vulgatum growing, felt 
positive that this was not that species nor any other with which 
we were familiar. I was delegated to describe and name it and 
decided to call it, from its habitat, O. arenarium. I sent a speci- 
men to Prof. Underwood, then at Kew, for comparison; after 
consulting with Mr. Baker, it was decided that it belonged to the 
section with O. dusitanicum, which has a similar gregarious habit, 
but differs in its much smaller size and narrower frond. 
Prof. Underwood has called my attention to a monograph of 
the genus by Prantl (Jarhb. d. K. Bot. Gart. Berlin, 3: 297-350. 
1884), in which two new North American species are described, 
thus far not included in our text-books, O. Engelmanni and O. Cal-
