Die Desmidiaceen Europas mit Berücksichtigung der aussereuropäischen Arten. (Dr. Rabenhorst’s Kryptogamen-Flora von Deutschland, Österreich und der Schweiz: 13). Vol. 1: 484 ( Krieger 1937).
DISTRIBUTION. — Cosmopolitan. Amazon Basin: Thomasson (1971). Western Amazonia (lowlands): no records.
DESCRIPTION
Cells 85.1-92.5 µm long, 40.8-41.0 µm wide, isthmus 12.4-13.2 µm; cells 2.1-2.3 times longer than wide. Cells with a deep median constriction, punctuated cell wall, closed sinus; trapezoidal semicells; basal lobes slightly rounded, lateral margins with one slight protuberance in the midway between the base and the apex of the cell; truncated to rounded apical lobe with a median notch relatively narrow, closed in each semicell apex.
REMARKS
Our specimens corresponded well in morphology with those described in Thomasson (1971) for the Brazilian Amazon. As Oliveira de et al. (2011a) mentioned, the specimens used by Krieger (1937) to describe the variety are larger than their specimens, which coincides with what was found in the present study.
