CHARA.

Hab. Serampore. 



This plant is remarkable for the Nitelline rami, and of 

 course ramuli, also for the size of these which are nearly 

 equal to the internodii of the rami, as well as for the mixed 

 disposition of the sexes, and for the red colour of the fe- 

 males, which have invariably the outer membrane unco- 

 loured, and the nucleus blackish. 



To the naked eye it has a green and white mottled appear- 

 ance, from which, and the abundance, and colour of the flow- 

 ers, it is rather conspicuous. This species was obtained for 

 me by Haloodar, Dr. Voigt's principal native Gardner. 



Some of the branches have only females ; ramuli even longer 

 than internodii, some variety occurs in the depth of red. 



Nitella as a genus, certainly cannot stand, it is only re- 

 tainable when compared with the more perfect CharaB, in 

 which only the ultimate ramules are simple.
