The fructification of Czekanowskia and its allies
Leptostrobus cancer n.sp. is described from well-preserved but broken material occurring in the Yorkshire Inferior Oolite (Middle Deltaic). Its fruiting appendages prove to be two-valved capsules, each valve housing a row of small seeds, probably of inverted orientation and with apical archegonia. T...

| Summary: | Leptostrobus cancer n.sp. is described from well-preserved but broken material occurring in the Yorkshire Inferior Oolite (Middle Deltaic). Its fruiting appendages prove to be two-valved capsules, each valve housing a row of small seeds, probably of inverted orientation and with apical archegonia. The new facts have led to a reinterpretation of Leptostrobus , and it is now recognized that the Greenland Liassic fossil Microcheiris enigma is the same as Leptostrobus longus . Circumstantial evidence is adduced for referring L. cancer to Solenites vimineus (also called Czekanowskia murrayana ) and other species of Leptostrobus to other species of Czekanowskia . Leptostrobus , as now understood, cannot be placed in any existing family, but for reasons of convenience no new family is at present instituted. |
