A note on Anotrichium tenue (C. Ag.) Näg. (Ceramiaceae, Rhodophyta) in southern Africa
Acta botanica neerlandica , Volume 34 - Issue 2 p. 145- 155
The red algal species Anotrichium tenue (C. Ag.) Nag. is reported from localities on the South African and Transkeian coasts. From this area the species has originally been described as Griffithsia secunda Harvey ex J. Ag. From morphological study it is concluded that the Cape material can be distinguished at varietal level, as Anotrichium tenue var. secundum (Harvey ex J. Ag.) nov. comb., nov. stat. It differs from the typical variety by its broader filaments, broader and less branched trichoblasts, and whorls with more numerous spermatangial clusters and tetrasporangia.
