OHARA HISPID A. 33 



always side by side, instead of one above another, and by the 

 rather larger fruit. 



The Linnean name has by common consent been retained for 

 this species. Dr. Nordstedt has pointed out the plant referred 

 to in the first reference in ' Species Plantarum,' was 0. aspera, 

 and in consequence of this preferred the name of 0. spinosa. 

 Our own view, as already explained, is that the Linnean name 

 covered all conspicuously spiny Charae then known. C. aspera, 

 C. aculeolata and C. rudis having been subsequently differen- 

 tiated, the name 0. hispida remains for the present species. 



A very large imperfectly-fruiting plant with long attenuate 

 branchlets, found in Hickhng Broad, E. Norfolk, appears to be 

 a hybrid between this species and G. contraria. When first 

 discovered it was referred to C. papillosa Kiitz., see ' Journ. Bot.'

Primary cortical-cells larger and more prominent 

 than the secondary, so that the spine-cells appear to be 

 seated on ridges.
