Derbesia is a genus of green algae in the family Derbesiaceae. [1] The plant was originally known from different names applied to its larger sporophyte, Derbesia, and its less conspicuous gametophyte, Halicystis. [2] Derbesia was successfully cultured in the laboratories of German phycologist Peter Kornmann to learn that both it and the plant Halicystis were different parts of the life cycle of the same organism. [3]
The genus name of Derbesia is in honour of Auguste Alphonse Derbès (1818–1894), French naturalist, zoologist and botanist, Professor of Natural Sciences at the University of Aix-Marseille. [4]
Lambia is a genus of green algae in the family Bryopsidaceae.
Pelvetia canaliculata, the channelled wrack, is a very common brown alga (Phaeophyceae) found on the rocks of the upper shores of Europe. It is the only species remaining in the monotypic genus Pelvetia. In 1999, the other members of this genus were reclassified as Silvetia due to differences of oogonium structure and of nucleic acid sequences of the rDNA.
Phyllospadix scouleri, or Scouler's surfgrass, is a flowering marine plant in the family Zosteraceae. It is native to the coastline of western North America from the Alaskan panhandle to Baja California.
Draparnaldia is a genus of freshwater green algae in the family Chaetophoraceae. Draparnaldia are uniseriate; each filament is composed of a chain of cells arranged in one row. Chloroplasts appear as a band within the center of each cell. The length of the main axis cells are generally the same, regardless of whether or not they bear branches. These side branches are divided extensively into terminal hairs. The entire plant is enveloped in loose, slippery mucilage. Draparnaldia is a cosmopolitan genus with wide distribution and it is usually found in cold aerated waters. They are either attached to sand or grow epiphytically on other aquatic plants. Draparnaldia can be seen growing in clear streams trailing on stones and boulders. Herman S. Forest of The Southern Appalachian Botanical Club has stated that while not common, it is present frequently enough to be recorded in almost all local flora lists of green algae that have been compiled. A multitude of species are present in Lake Baikal, Siberia and have been described by Meyer and Jasnitzky. A species of the genus had been placed and described in the Linnean Herbarium as Conferva mutabilis Roth in 1797. Nowadays Conferva is no longer used and the species is described as Draparnaldia mutabilis (Roth) Bory. Bory is added in honour of the researcher of the same name, based on whose description the genus was separated from similar appearing forms. Bory is accredited with the establishment of the genus.
Floydiella is a genus of green algae in the family Chaetopeltidaceae.
Fritschiella is a genus of green algae, the only genus in the family Fritschiellaceae. There are two species F. tuberosa and a new freshwater species from China, F. aquatilis
Gomontia is a genus of green algae, in the family Gomontiaceae.
Hazenia is a genus of green algae in the family Gayraliaceae.
Paulschulzia is a genus of green algae, specifically of the family Tetrasporaceae.
Trentepohlia is a genus of filamentous chlorophyte green algae in the family Trentepohliaceae, living free on terrestrial supports such as tree trunks and wet rocks or symbiotically in lichens. The filaments of Trentepohlia have a strong orange colour caused by the presence of large quantities of carotenoid pigments which mask the green of the chlorophyll.
