Carolyn Ricci and Bob Baldock from the State Herbarium’s Phycology Unit report that the alga is often found in calcium-rich waters. Its central stalks are ribbed with cells that accumulate lime crystals, and there are rings of stiff side branches ending in points.
The female organs are bottle-shaped, wrapped in five twisted cells and stoppered with a cellular plug. Male organs in this species are spherical, lurk just beneath the females and are orange.
Who said that algae are simple life forms?
