ASPLENIUM EBENOIDES 495 
A. ebenoides in habit, coloring, texture, form of the leaf, venation, 
and character of the scales ; in short, it does not possess one char- 
acteristic that A. edencides does not possess at some time in its life 
history, and, though young, lacks of the characteristics of A. 
ebenordes only the possession of sori and elongation and attenua- 
tion of the pinnae, both of which are often absent in A. ebencides 
at the same age. Surely we have here convincing proof of the 
origin of A. ebenoides.
