(The male flowers of Elodea canadensis, hitherto unknown in 

 Britain, are here recorded from Scotland and are described and 

 figured.)

(An historical account of the different views which have been 

 held on the question whether the male flowers of Vattisneria 

 do or do not become detached from their pedicels and float to 

 the surface of the water.)

 [p. 261] plantes dans les milieux humides. Bull, de la Soc. bot. 



de France, T. v. 1858, pp. 105-111. 

 (The author concludes from his experiments that the transpira- 

 tion of a terrestrial plant can continue when it is grown in 

 a saturated atmosphere or even when it is completely immersed 

 in water.)

 France, T. xix. 1872, pp. 289-302. 

 [The author shows that, in the absence of the organs of 

 fructification, Zostera and Cymodocea can be distinguished by 

 their anatomy. This analysis of the anatomical characters of 

 marine Angiosperms was carried much further by another 

 French observer about twenty years later; see Sauvageau, C. 

 (1890') and following titles.]
