Berry: NOTES ON THE GENUS WIDDRINGTONITES 343 
However admirable this arrangement may be when only the 
living species are considered, it will not answer for the fossil forms, 
and paleobotanists quite rightly maintain the various genera 
Frenelites, Frenelopsis, Widdringtonia, Widdringtonites, Callitris, 
etc., ranging in age from the older Mesozoic through the Tertiary 
and abundantly fortified by fruiting specimens. Fossil fruits of 
still other species and perhaps genera occur in the late Tertiary 
formations of Australia, the weight of the evidence showing that 
this type was considerably more varied in the past, the existing
