174 THE LATE DR. NEWELL ARBER: CRITICAL STUDIES 
Lepidophyllum should be restricted to Lycopod leaves, pure and simple. If, 
in making a record of one of these cones, only a detached sporophyll is 
known from a particular locality, the fact can be illustrated as in the 
following example :—Lepidostrobus lanceolatus, Lindl. & Hutt. [Sporophyll]. 
The Sublepidostrobi are the rarest and least known type in Britain, and in 
no case have we any complete knowledge of the sporophylls except the 
distal portions.
