Article: Three fructifications from the Scottish Lower Carboniferous
D. L. Smith
This paper gives descriptions of three fructifications from a Lower Carboniferous horizon in the Kilpatrick Hills, Dunbartonshire. Two new specimens of Protopitys scotica Walton provide further information about the structure of the stem and spores of this species. Staphylotheca kilpatrickensis gen. et sp. nov., probably the pollen-bearing organ of a pteridosperm, has yielded fertile and abortive spores. Calathiops trisperma sp. nov. is a pteridosperm fructification consisting of small cupules, each containing three ovules. The affinities of the three species are discussed briefly.
