were described by Harvey as Halymenia membranacea (1844). 

 A specimen is'preserved at Kew. Harvey in his description noted 

 the dot-like markings but regarded them as tctraspores, a mistake 

 which he himself pointed out later. In 1847 when compiling his 

 list of Tasmanian Algae he records the plant as Rhodymenia 

 membranacea. Kiitzing, in the same year, having seen an 

 authentic specimen, considered it the type of a new genus, and 

 named it StichophyUum membranacea. This name he retained 



««*&» ? pecies - vl g a ™m in 1849. In the Flora of New Zealand 

 (18o5) Harvey records the plant as gathered by Lyall and Colenso 

 in that country; specimens from both of these collections are at 

 Kew, and they agree in all respects with the type specimen from 

 lasmania. Harvey's description and figure in Fl. New Zeal, is 

 excellent. Up to this date there is no difficulty. In 1860, 

 however Harvey in Flora Tasmaniae united R. fimbriata with
