ON THE OCCURRENCE OE A SEED-LIKE FRUCTI¬ 
FICATION IN CERTAIN PALAEOZOIC LYCQPOBS \ By 
D. H. Scott, M.A., Ph.D., F.R.S.—It has generally been assumed 
by palaeobotanists that the fossil seeds described by Williamson 2 
under the name of Cardiocarpon , even if not necessarily co-generic 
with the Cardiocarpus 3 of Brongniart, at least belonged to the same 
group of Gymnospermous plants 4 . Brongniart’s specimens, often 
preserved with marvellous perfection, have proved to be the seeds 
of members of the extinct Order Cordaiteae, or of allied plants. 
The same conclusion applies to certain of the British forms, notably 
the Cardiocarpon anomalum of Carruthers 5 , which was certainly 
Cordaitean, and probably to some of Williamson’s examples. 
The specimens to be shortly described in the present note show, 
however, that seed-like bodies, identical with those figured by 
Williamson under the name of Cardiocarpon anomalum 6 , were borne on 
Lepidodendroid cones, otherwise indistinguishable from Lepidoslrobus. 
They thus prove that under the genus Cardiocarpon , and even under 
the * species ’ C. anomalum , totally different objects have been con¬ 
founded, namely, the seeds of Cordaiteae or Cycads on the one hand,

identified with the Lepidostroboid fructification. Others figured by Williamson 
are of doubtful nature.
