  1. 1.

    The marine red algaLenormandia prolifera containsα-cryptoxanthin, a monohydroxy derivative ofα-carotene, as well asα- and β-carotene, lutein and zeaxanthin.

  2. 2.

    Chlorophylla and a trace of chlorophyllidea is present but no chlorophylld.

  3. 3.

    The chlorophyll/carotenoid ratio is 2.5 ± 0.7 (w/w), falling within the range reported for other species of the Rhodophyta.

  4. 4.

    α-Carotene is more abundant thanβ-carotene while lutein is the most abundant xanthophyll;α-cryptoxanthin accounts for only 2.4% of the total carotenoid content.

  5. 5.

    The possibility that theAmansia group is distinguished by containingα-cryptoxanthin and moreα- thanβ-carotene is discussed.
