162 A REVIEW OF THE BRITISH CHARACEiE. 



3. TOLYPELLA. 



Leonhardi in Lotos (1863), p. 12. 



Branches many at each node. Branchlets simple or dividing 

 into unequal rays. Globules lateral at the forkings of the branchlets, 

 and usually surrounded by a number of nucules. Nucules also 

 produced at the nodes of the fertile whorls. Monoecious.

Stem moderately stout, producing many branches at tbe 

 principal nodes. Sterile whorls of 6-12 long, simple, obtuse, 3-5 

 jointed brancblets. Fertile whorls in dense compound beads; 

 brancblets once divided, into 3-4, unequal, 3-5-celled, obtuse rays. 

 Nucules stalked or sessile, ovoid, 8-9- striate ; spiral cells 

 prominent. Globules usually stalked. (Tab. 209, f. 11.) 



Mucb encrusted and very brittle. The strongly-curved rays 

 give tbe fertile wborls a peculiarly contorted appearance. It is 

 recorded by Braun from Em-ope (North, Mid, and South), Asia, 

 Nortb Africa, and Australia ; in Britain it is rare, and apparently 

 almost confined to the South-east of England.
