YELLOW‐GREEN ALGAE WITH CHLOROPHYLLIDE C1,2

Abstract
SUMMARY: Chlorophyllide c (chlorophyll c) wax found in axenic or unialgal cultures of 5 members of the class Xanthophyceae and in 2 members of the class Raphidophyceae (Chloromonadophyceae).Two other algae contained no chl c; neither had chl b. One of these plants, Pleurochloris magna, is presumably a member of the newly named class Eustigmatophyceae (Hibberd and Leedale). The other alga, clone GSB Sticho, is of uncertain, systematic position.Although, the xanthophyll pigments were not critically studied, there is enough evidence, to permit the conclusion that the xanthophyll suites of the chloromonads, the xanthophytes, P. magna, and clone GSB Sticho all differ in at least one respect.
