Heimansia is a genus of freshwater green algae, specifically of the Desmidiaceae.[2]
The genus name of Heimansia is in honour of Jacobus Heimans (1889-1978), who was a Dutch botanist (Bryology and Algology) and was Curator of the Herbarium at the University of Amsterdam.[3]
The genus was circumscribed by Peter F. M. Coesel in Crypt. Algol. vol.14 on page 107 in 1993.
Description
[edit]Heimansia consists of small, branched filaments or colonies. The cells are held together by remnants of the parental cell walls, which sometimes forms an "H"-shape between the cells. Individual cells of Heimansia are constricted, with two broadly ellipsoidal halves (semicells); each semicell has a single axial chloroplast. The cell walls are smooth.[4]
Heimansia is similar to Cosmocladium, from which it differs in having cells connected by cell wall remnants (as opposed to microfibrillar threads in Cosmocladium).[4]
