The art of arranging marine algae into designs, bouquets, and even sometimes intricate little scenes, was surprisingly popular in the 19th century. See an album of such pictures by a woman named Eliza A. Jordson here: https://publicdomainreview.org/collection/album-of-seaweed-pictures-1848

Oooh I’ve seen that before! I don’t think they’re sporophylls- maybe for some reason the blades can have a bumpy texture in the same way that the pneumatocysts and rachis do? And the more rounded, smaller bladelets might just be younger ones. But who knows! Egregia’s so wonderfully weird…
