Charophyceae

Viridiophytes: green plants

Although it is now generally accepted that charophyceans are the closest living relatives of the land plants, molecular analyses have not fully resolved this relationship. Various analyses have suggested charaleans, early-divergent charophyceans (Coleochaete, Klebsormidium) or zygnemataleans as closest to plants. Here we opt for a conservative approach in which the embryophytes emerge basally to the entire charophycean class, pending further conclusive evidence.

Indigenous or exotic to New Zealand.
