Egregia menziesii - Feather boa

Family: Lessoniaceae [E-flora]


Food Use


Egregia Sp. - 18-20% algin by dry wt. [Chapman SU]


"Several of the Phaeophyta investigated, notably Egregia Menziesii and Postelsia palmaeformis, showed slight activity against Staphylococcus aureus (Micrococcus pyogenes var. aureus), Bacillus megatherium, Pseudomonas aeruginosa, Escherichia coli and Mycobacterium tuberculosis H 37 Rv. The inhibition is not due to iodine but appears to be caused by organic compounds, the nature of which has not yet been determined." [Mautner]

Uses of Other Related Sp.

"In the mid-intertidal zone, early-successional algae competitively inhibit a mid-successional association of red algae, which in turn competitively inhibit the late-successional Gigartina association (Sousa 1979). In its turn, the Gigartina turf outcompetes the kelp Egregia laevigata, which recruits only from spores and only at certain times of the year." [Lobban SEP]

Synonyms: Fucus menziesii [NPS-E-flora]
