"This monograph is another proof of the high degree of perfection that can nowadays be 

 reached in cryptogamy. Modern communications are such that there is no need anymore 

 not to consult all basic material, whereevcr it may be, provided of course it is extant. Most 

 taxonomic mstitutes are now also equipped to do cytological and chemical research, The 

 notion that held-study is a primary condition also for cryptogamy is fortunately wide-spread. 

 The mam conditions tor a work like this, however, remain that of undivided devotion to 

 one's subject, perseverance to master all details, and a thorough knowledge oi the meaning 

 of taxonomy in all its facets. The Revision oi the Characeae by Wood and Imahori is proof 

 that these conditions have been met with great success."
