Batrachospermaceae
Batrachospermaceae is a family of fresh water red algae Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority ... (Rhodophyta). Genera within the Batrachospermaceae generally have a "''Lemanea-''type" life history with carpospores germinating to produce chantransia. Sporophyte phase with meiosis occurs in an apical cell to produce the gametophyte stage. Pit connections have two pit plug cap layers with the other layer enlarged. This family of freshwater red algae is uniaxial, meaning each filament with a single apical cell. The genera included within Batrachospermaceae are listed in the table below.

Sirodotia
''Sirodotia'' Kylin (1912) is a genus of freshwater red alga which was described by Kylin in 1912, and placed in the Batrachospermaceae family. The genus name of ''Sirodotia'' is in honour of Simon Sirodot (1825–1903), who was a French botanist, algologist and teacher. He was also a Zoologist and Archaeologist, who taught at schools in Toulouse, Strasbourg, Le Mans, Cahors and Limoges. Taxonomy The family Batrachospermaceae belongs to the order Batrachospermales and has six well known genera namely '' Batrachospermum'', '' Kumanoa'', ''Sirodotia'', '' Nothocladus'', '' Tuomeya'', and '' Sheathia''. The morphology of the gametophyte of ''Batrachospermum'', ''Sirodotia'', ''Tuomeya'', and ''Nothocladus'' are more are less similar to each other. Necchi and Entwisle (1990) proposed to delimit them from generic level to section level of genus ''Batrachospermum''. ''Sheathia'' was the member of genus ''Batrachospermum'' and has risen to generic level. phylogenetic studies revea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timothy John Entwisle
Timothy John Entwisle (born 1960), is an Australian botanist, much of whose research work is in phycology (algae). See for example the articles. He was awarded a Ph.D. from La Trobe University in 1986 for work on the taxonomy of '' Vaucheria''. He was New South Wales’ Government Botanist in 2007 and 2008, and for eight years was the executive director of the Royal Botanic Gardens Sydney (2003–2011). Subsequently, he was director of Conservation, Living Collections and Estates, Kew, London from 2011, and since 2013 he has been director of the Royal Botanic Gardens Victoria. He is an honorary professorial fellow at the University of Melbourne and is currently (2020) president of the International Association of Botanic Gardens. As director of the Royal Botanic Gardens Sydney, Entwisle managed Sydney's Royal Botanic Gardens, the Mount Tomah Botanic Garden, in the Blue Mountains and the Mount Annan Botanic Garden, near Camden, and at Kew, he was responsible for Kew Gard ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

William Henry Harvey
William Henry Harvey, FRS FLS (5 February 1811 – 15 May 1866) was an Irish botanist and phycologist who specialised in algae. Biography Harvey was born at Summerville near Limerick, Ireland, in 1811, the youngest of 11 children. His father Joseph Massey Harvey, was a Quaker and prominent merchant. William started his education at Ballitore School in County Kildare and by the age of 15 had already established algae as his over-riding interest.Papenfuss, G.F. 1976. pp.21–46. Landmarks in Pacific North American Marine Phycology. ''in'' Abbott, I.A. and Hollenberg, G.J. 1976. ''Marine Algae of California''. Stanford University Press, California. After leaving school he joined the family business. Harvey was an authority on algae and bryophytes (mosses), and author of ''A Manual of the British Algae'' (1841), ''Phycologia Britannica'' (4 vols., 1846–51), ''Nereis Boreali-Americana.'' (3 parts 1852–85) and ''Phycologia Australica'' (5 vol., 1858–63). He spent several ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
