Lithothamnium australe Foslie 

 Including f. americana Foslie and f. tualensis Foslie 



Foslie 1895b, p. 8, figs. 6, 7 (as L. coralloides f. australis) ; 1900c, 

 p. 13 (f. americana as a nomen nudum) ; 1904, p. 25. 



Foslie (1895a, p. 90, pi. 16, figs. 24-31) figured plants from northern 

 Europe as L. coralloides f. australis and indicated this, with others which 

 he described in Latin, as new forms of the species, "mscr." However, he 

 uses the same name (1895b, p. 8, figs. 6, 7) for a plant from "Cali- 

 fornia,"i"3 a^j j^g finally designates the latter plant as L. australe f. 



102 However, see Setchell & Mason 1943, p. 94, who discard this name. 



103 Actually, the Gulf of California, according to a later paper (1904, p. 25).
