Triploceras is a genus of desmid (a type of green alga) in the family Desmidiaceae. [2]
Triploceras exists as solitary cells, which are elongated and constricted at the middle (the constriction called an isthmus); the two halves are called semicells. At tip of either semicell, the cell is tipped with spiny lobes, similar to the polar lobes found in Micrasterias . Along the margins of the semicells are many whorls of processes that may be tipped with spines or teeth. Cells have one chloroplast filling the cell. [3]
Triploceras is easily recognizable due to its elongated shape and polar lobes. [3] The similar genus Triplastrum also has polar spines, but lacks protuberances along the sides of the cell. [4]
Phylogenetically, Triploceras is currently known to be embedded within the genus Micrasterias. [3] [4] Despite the similar rod-like shape, it is not closely related to other rod-shaped genera such as Pleurotaenium or Triplastrum. [4]
Two species, Triploceras gracile and T. verticillatum are widely distributed throughout the world. Another species, T. splendens is rare and restricted to Southeast Asia and northern Australia. [1]
Desmidiales, commonly called the desmids, are an order in the Charophyta, a division of green algae in which the land plants (Embryophyta) emerged. Desmids consist of single-celled microscopic green algae. Because desmids are highly symmetrical, attractive, and come in a diversity of forms, they are popular subjects for microscopists, both amateur and professional.
Euastrum oblongum is a species of desmid, in the family Desmidiaceae.
Micrasterias is a unicellular green alga of the order Desmidiales. Its species vary in size reaching up to hundreds of microns.
Chlainomonas is a genus of algae in the family Chlamydomonadaceae. They are found in freshwater habitats or on snow, where they are one of the main algae responsible for causing watermelon snow.
Quadrigula is a genus of green algae in the family Selenastraceae. It is commonly found in freshwater habitats as phytoplankton.
Sorastrum is a genus of green algae in the family Hydrodictyaceae. It is a component of the phytoplankton of freshwater ponds, lakes, and ditches. Sorastrum is common in tropical to temperate regions of the world, but due to its small size it is often overlooked.
Treubaria is a genus of microscopic green algae, the sole genus in the family Treubariaceae. Treubaria is found in freshwater habitats and has a cosmopolitan distribution.
The Closteriaceae are one of four families of Charophyte green algae in the order Desmidiales (desmids). It contains two genera, Closterium and Spinoclosterium.
The Desmidiaceae are one of four families of charophyte green algae in the order Desmidiales (desmids).
Closterium is a genus of desmid, a group of charophyte green algae. It is placed in the family Closteriaceae. Species of Closterium are a common component of freshwater microalgae flora worldwide.
Cosmarium is a large genus of desmids (Desmidiaceae), a group of green algae closely related to the land plants (Embryophyta). Members of this genus are microscopic and found in freshwater habitats around the world.
Desmidium is a genus of green algae, specifically of the Desmidiaceae.
Pleurotaenium is a genus of green algae, specifically of the desmids (Desmidiaceae).
Spinoclosterium is a genus of green algae, specifically of the Closteriaceae. It is rare, but widely distributed in freshwater regions throughout the world.
Staurastrum is a large genus of desmids (Desmidiaceae), a group of green algae closely related to the land plants (Embryophyta). Members of this genus are microscopic and found in freshwater habitats around the world.
Staurodesmus is a genus of green algae, specifically of the Desmidiaceae.
Xanthidium is a genus of green algae, specifically of the Desmidiaceae.
Micrasterias furcata is a species of unicellular desmid which inhabits freshwater areas. M. furcata is round, flattened and lobed in body plan.
Cosmarium botrytis is a species of green algae in the family Desmidiaceae. It is a freshwater species with a worldwide distribution, and has been recorded from all continents.
Prescottiella is a genus of green algae in the family Desmidiaceae, containing the single species Prescottiella sudanensis. Originally classified as Micrasterias sudanensis in 1958, it was moved into its own genus by Carlos E. M. Bicudo in 1976, due to its asymmetric character. It is named after Gerald Webber Prescott, an American phycologist.
