II.—On Some Cycadean Fruits from the Secondary Rocks of Britain

Abstract

Two of the Gymnospermatous Orders are represented by fruits found in Secondary strata, viz., Cycadeœ and Coniferœ; no remains have been observed, as far as I know of any plant belonging to the Gnetaceœ.. There is satisfactory evidence of the existence of Coniferœ from the period of the Old Red Sandstone; but it is very doubtful whether the Palæozoic fruits and leaves which have been referred to Cycadeœ have anything whatever to do with that order.
