This variety corresponds to the yellow variety of Alcyonium digitatum which 
HICKSON noticed in 1894. Further species, described as Sympodium massa EHRENBERG, 
Sympodium margaritaceum GRIEG, and Haimea hyalina Kor. and DaAN., belong to this 
variety of ÅA. digitatum. May (1900) and KÖKENTHAL (1906 a) consider Sympodium 
margaritaceum GRIEG to be Clavularia. KÖUKENTHAL (1906 a) refers the membranous form 
of this variety to his sub-genus Erythropodium, and BrRocH (1912) proves that Haimea 
hyalina is a young specimen of the Å. digitatum var. norvegicum.
