Description Relatively large cells, broadly ovoidal, tapering ventrally in apical viewPlate 1’ peculiar and heptagonal, i.e. having a suture with 5’’, which is not present in other species. Plate 2’ small, about twice the size of Po. Cingulum very narrow (1.5–3.0 μm). Sulcus recessed and hidden, transversally elongated. Plate 2’’’’ long, and broadest ventrally. Theca ornamented with many small protuberances containing a pore (0.30 μm in diameter, Faust et al. 1996). An heptagonal plate 1’ has also been found in cultures of O. ovata (Besada et al. 1982) in an aberrant specimen, and more recently in a strain of O. cf. ovata by Penna et al. (2010). Although these species are much smaller in size than O. heptagona, the heptagonal shape of the 1’ plate is not an unambiguous character to identify this species. [details]

[details]Harmful effect There are no records of toxin production by this species in nature. However, when originally described from Florida (Norris et al. 1985), cultured cells showed limited toxicity based on the mouse bioassay [details]
