(Figs. 3 A-C)
Cells 1-2 times greater in length than width, 15-43 × 13-22 μm, 8-14 μm broad at the apex and 12-22 μm wide at the isthmus. Semicells pyramidal-truncated and barrel-shaped; parallel lateral margins, narrow towards the apex; broad and truncated apex; small basal inflation on either side of the isthmus; open median constriction; shallow median sinus; hyaline cell wall; axial chloroplast.

Comments: the present specimens did not show the longitudinal striation at the apex of semicells. Ralfs (1848) identified this species as Desmidium borreri Ralfs. However, in 1845, the same species was identified as Bambusina brebissonii Kützing by Kützing (1845), and it was validated by the same author in Kützing 1849. Cleve (1864) clarified that Bambusina borreri, based on Ralfs’ material, was synonymous to B. brebissonii. Gontcharov (2008) designated Bambusina borreri as the type species of Bambusina. However, according to Guiry (2013), this was incorrect because B. brebissonii Kützing ex Kützing was included in its original publication as a heterotypic synonym of B. borreri. Due to this, according to the latter author, B. brebissonii must be considered the type species of Bambusina and a ‘nomen conservadum’ for Gymozyga Ehremberg ex Kützing. D. borreri should be considered as a basionym and B. borreri as a synonym for B. brebissonii.
