#3794 - Cystophora retroflexa

First described as Fucus retroflexus by French naturalist Jacques Labillardière in 1807. It became the type species of the genus Cystophora in 1848, when it was renamed by Swedish botanist, phycologist, and taxonomist J.G. Agardh in 1848. 'retroflexa' refers to the way the lateral branches of the fronds are bent backwards.

A brown algae found on NZ and Australian coastlines, but preferring more sheltered reefs than other Cystophora species.

Summer Kelp & Seaweeds

[goodrichthyseskdalensis]

You wanna know something ultimately inconsequential that still manages to annoy me? The fact that so much media displays kelp as green. Like I get that it doesn't really matter but come on! They're literally a kind of brown algae! It's in the name! I just want one piece of media that accurately reflects the beautiful golden browns of kelp.

#3715 - Marginariella urvilliana

Originally named Marginaria urvilliana by French botanist, botanical illustrator and physician Achille Richard in 1832, but later renamed because Marginaria was already used for a type of fern. The binomial refers to the small reproductive receptacle fringing the fronds, and Captain Jules Dumont d'Urville, a French explorer who collected the seaweed during his 1827 visit to New Zealand on the ship Astrolabe.

The seaweed take three years to reach maturity, but produces gametes annually from that point onwards.

All three species in the genus are endemic to the region of New Zealand, urvilliana is found around the South Island, Rakiura Stewart Island, and the Chathams.
