In-Depth Information
Distribution: Australia, New Zealand
Habitat: Freshwater habitats
Description: In this ilamentous species, the ilaments are unbranched or
slightly false-branched. They may be thick or rarely solitary. They are usu-
ally connected into thick-layered or leathery strata (mats). The trichomes
(6-50 µm long) of this species are straight or slightly wavy.
Compounds and activities: The monounsaturated fatty acids, viz., palmitoleic
and oleic acids, isolated from this species have been reported to prevent
high glucose concentration and improve β cell secretory functions (Smith
et al., 2008).
