Mr. Baker says that the groups of 

 veins often join, this I have not 

 seen in my specimens ; but very 

 rarely the two forks of the vein join 

 each other before running out at the 

 margin; the veinlet is also always con- 

 tinued beyond the sorus, I have never 

 found a terminal sorus, though they 

 often appear to be so until the frond is 

 held up to the light.
