The Woodsia which grows on the quartzite rocks iu Gitchie Manitou State Park, in Lyon county at the ex- treme northwest corner of the state, has been reported both as W. scopulina and W. oregana; but a visit there disclosed that it is neither, as it shows instead the dense glandularity characteristic of W. cathcartiana. " South Dakota.—There being reports of both Woodsia oregana and W. mexicana in the Black Hills, some atten- tion was paid to this group there, especially in the Custer State Park. No trace of the glabrous fern bearing the former name, or of the downwardly narrowed, thick- margined, conspicuously hairy-indusiate Mexican Cliff- fern could be found. Instead the plants seen were all more or less intermediate between these two extremes, the margins being more or less thickened—never markedly so -and short-stalked glands being present on vascular parts, but sparse or lacking on laminar tissue. Here, as in western Iowa, W. cathcartiana seems unciuestionably represented, although some material appears to lie inter- mediate between that and some other species, and will require detailed study for proper classification and nam- Oklahoma.—During August a brief visit was made to Cimarron, the northwesternmost county, to look for the ^* 4 - « * IRREGULAR PAGINATION.
