Type designated in Desikachary, T.V. (1959). Cyanophyta. pp. [i]-x, -686, pls 1-139. New Delhi: Indian Council of Agricultural Research.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
Most recent taxonomic treatment adopted: Komárek, J., Kaštovský, J., Mares, J. & Johansen, J.R. (2014). Taxonomic classification of cyanoprokaryotes (cyanobacterial genera) 2014, using a polyphasic approach. Preslia 86: 295-335.
Description: Filaments heteropolar, rarely straight and erect, usually creeping on the substrate, but distinctly divided into basal end with a heterocyte and the apical end, simple, unbranched, solitary or in small, microscopic groups. Trichomes with basal, more or less spherical or hemispherical heterocytes, occasionally also with intercalary, cylindrical heterocytes; at intercalary heterocytes sometimes division of trichomes and their dissociation; trichomes cylindrical, not attenuated, but sometimes with slightly widened apical parts, constricted at the crosswalls. Sheaths always present, firm, thin, colorless, open at the ends. Cells cylindrical or barrel-shaped, sometimes more rounded at the ends, without aerotopes, but sometimes with a granular content, blue-green, yellowish or pale grayish blue. Akinetes poorly known. Cell division perpendicular to long axis of trichomes (subapical meristematic zones). Trichomes dissociate into hormogonia in the upper part with the help of necridic cells. Reproduction by hormogonia, which develop by a special manner: in their middle develop one or two heterocytes, which separate 2 filaments one from another and change into basal heterocytes. Epiphytic and epilithic species, growing submerged in unpolluted freshwater biotopes. Majority of species described from tropical countries and known usually only from few localities.

Numbers of names and species: There are 13 species names in the database at present, of which 11 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.
Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
