On the Circinate Vernation, Fructification, and Varieties of Sphenopteris affinis , and on Staphylopteris (?) Peachii of Etheridge and Balfour, a Genus of Plants new to British Rocks

Abstract

Conclusion Staphylopteris (?) has been found by myself in the “blaes” (once in an ironstone nodule amongst the “blaes”), rather plentiful at West Hermand, West Calder; by Mr. Bennie, fossil-collector for the Geological Survey of Scotland, in shales at Currie, near Slateford; at Straiton, near Burdiehouse, in a piece of shale at the oil-shale pit, by Mr. D. J. Brown, of Edinburgh, and Mr. Bennie. All these localities are in the Calciferous Sandstones of the Carboniferous formation of Scotland. All the diagrams were made by myself from specimens I collected. I send, with two exceptions (which are in the British Museum, but were also collected by myself), all the specimens figured; so that the Members can see for themselves how far they are to be trusted. One more remark. None of the American specimens of Staphylopteris agree with the British one; and thus Professor Balfour's wish as to species has been carried out.
