The genus was circumscribed by Ernst Johann Lemmermann in Hedwigia vol.37 on page 311 in 1898. The genus name of Schroederia is in honour of Ludwig Julius Bruno Schröder (1867–1928), who was a German teacher, botanist (Algology and Bryology), also Hydrobiologist and Zoologist. He worked as a deputy head teacher in Breslau.[3]
Description
Schroederia consists of solitary cells that are needle- or spindle-shaped. They may be straight or curved. The cells end in long spines; at one end the spine may be bifurcated. Cells contain a single parietal chloroplast and one or several pyrenoids.[4] As the cell matures, it develops multiple parietal chloroplasts along its long axis.[5] Cells have one nucleus (uninucleate) when young but may become multinucleate.[1]
Species are distinguished from one another by their overall shape and size.[1]
Reproduction
Distribution
Schroederia is commonly found in as phytoplankton in freshwater habitats.[4] It has an essentially cosmopolitan distribution, being found in tropical and temperate habitats worldwide.[1]
