Description:
Unicellular green flagellates, growing in water or soil habitats, capable of forming symbioses. Cells about 2.5-7 (10) µm in length and 1-4.5 µm in diameter, asymmetrical, ovoid to ellipsoid, often distinctly flattened. A single, long flagellum in lateral to subapical position, inserted in a shallow groove or flagellar pit, curved backwards around the resting cell, directed backward during swimming, usually covered by long, delicate flagellar hairs. Flagellum connected to the mature no.1 basal body, accompanied by a short immature no. 2 basal body without flagellum. Basal bodies arranged antiparallel and displaced in 11/5 o'clock position, associated with a cruciate system of four microtubular flagellar roots and one or two rhizoplasts. Cells usually naked, rarely covered by tubercles or subtle scale-like particles, or incompletely enclosed by a theca confined to the posterior part of the cell. Non-flagellate palmelloid stages covered by mucilage. A single lateral chloroplast with pyrenoid, surrounded by two membranes, with chlorophylls a and b, without prasinoxanthin. Eyespot single-layered, positioned between pyrenoid and chloroplast envelope, opposite flagellar insertion, flanked by microtubular 1 s and 1d flagellar roots, divided during cell division. Mitosis closed, involving a persistent interzonal telophase spindle, without phycoplast. Third/second from last base pairs in Helix E24 [H1792] of the nuclear 28S rRNA are G-C/G-C instead of U-A/C-G; base pair 4 of Helix B1 [bp 18/522] in the plastid-encoded 23S rRNA is A-U instead of C-G.
