2 58 Campbell— Life- History of Isoetes . 
Mr. Farmer asserts for I. lacustris , and this is certainly not 
determined by the first division of the primary nucleus. This 
being the case, the comparison he draws (p. 59) between 
Isoetes and the angiosperms can hardly be maintained. 
The conclusions as to the affinities of Isoetes are the same, 
regarding it as belonging rather to the Filicineae than the 
Lycopodineae.
