THE LIVER- WORT TRIBE. 



Plants growing on the earth or trees, in damp places, all over the world, 

 except where excessive dryness prevails. In India they are but imperfectly 

 known, so that out of 237 species enumerated by Sprengel only 25 Indian 

 ones have been named by Lehmann, according to Wall. Cat., viz. 5 of 

 Marchantia ; 1 of Grimaldia ; 2 of Plagiochasma ; 4 of Fimbriaria ; 1 of 

 Dumortiera ; 1 oi Riccia ; \0 oi Jungermannia ; and 1 of Blandovia ; all, 

 with 4 exceptions, natives of Nepal, and the Khassya Mountains. — Royle 

 adds to the above Marchantia polymorpha, L. and Jungermannia scor- 

 pidides, Nees. — Griffith's collection of Marchantiaceae on the Khassya Hills 

 and in Assam amounts to 48 species. Properties " unknown." {Lindl.)
