HAB. In pools and streams of water; rarely fructifying 



but in places that are only occasionally inundated. 

 Stems often a span long. Colour varying from pale green to 

 a deep purple in alpine rivulets. It has seemed so doubtful 

 where this species should be arranged, that, following the 

 opinion of Mohr, we have placed it under the section of 

 " Leaves falcato-secund," instead of leaving it in the division 

 where we had arranged it in our first edition. 

 59. H. aduncum; leaves falcato-secund lanceolate- subulate con- 

 cave or almost semicylindrical entire the nerve disappearing 

 below the summit, capsule oblongo-ovate curved cernuous, 

 lid conical. (TAB. XXVI.) 



. revolvens ; leaves narrow, very much falcate.
