2. CRYPTOGAMS 



Much less is known about the carotenoids of cryptogams than about the 

 carotenoids of phanerogams, no doubt partly due to the greater difficulty of 

 collecting experimental material. Recent investigations, however, have yielded 

 such interesting results that further studies in this field appear very desirable.
