1 See remarks in the Preface. For practical purposes the student may arrange his 

 collection in two principal groups, Foliaceous and Frondose; the former subdivided 

 iccording to the presence or absence of stipules (so called) on the stems. The latter 

 form a natural transition to the Marchantiacese.* See M. C. Cooke, ' British Hepatica?.'
