Charales

Viridiophytes: green plants -> Charophyceae

Charales, also known as stoneworts due to their ability to accumulate calcium, are easily confused with embryophytes. They are macroalgae with a similar appearance to pond weed, and were an early focus in the search for land plant origins. Relationships within the group have been well studied both regionally and globally; here we present a synthesis of some of the notable studies.

Indigenous or exotic to New Zealand.
