Salix herbacea, the dwarf willow, least willow or snowbed willow, is a species of tiny creeping willow adapted to survive in harsh arctic and subarctic environments. Distributed widely in alpine and arctic environments around the North Atlantic Ocean, it is one of the smallest woody plants.
Koncordie Amalie Dietrich was a German naturalist who was best known for her work in Australia from 1863 to 1872, collecting specimens for the Museum Godeffroy in Hamburg.
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago.
Lemanea is a genus of freshwater red algae, in the order Batrachospermales. Both species are considered to be widespread in the northern hemisphere. Although placed in the Rhodophyta it in fact is green in colour.
Tetraneuris herbacea is a rare species of flowering plant in the aster family known by the common names eastern fournerved daisy, lakeside daisy, fournerved starflower, and Manitoulin gold. It is native to and endemic to the Great Lakes region in North America, where it is present in Ontario, Ohio, Michigan, and Illinois. It is threatened by habitat destruction and degradation by several forces, including limestone quarrying, recreational activity, fire suppression, and construction. It is a federally listed threatened species of the United States and of Canada.
Desmarestiaceae is a family of brown algae, one of two families in the order Desmarestiales. The family gets its name from the genus Desmarestia, which is named after the French zoologist Anselme Gaëtan Desmarest (1784-1838).
Desmarestia is a genus of brown algae found worldwide. It is also called acid weed, acidweed, oseille de mer, sea sorrel, ウルシグサ, stacheltang, mermaid's hair, landlady's wig, or gruagach. However, 'sea sorrel' can also specifically refer to Desmarestia viridis. Members of this genus can be either annual or perennial. Annual members of this genus store sulfuric acid in intracellular vacuoles. When exposed to air they release the acid, thereby destroying themselves and nearby seaweeds in the process. They are found in shallow intertidal zones.
Firoloida is a monotypic genus of pelagic marine gastropod mollusc in the family Pterotracheidae, with the only species in the genus being Firoloida desmarestia. This shell-less mollusc is found in tropical and sub-tropical waters in the epipelagic zone of the world's oceans.
Desmarestia tropica, sometimes called tropical acidweed, is a species of seaweed in the family Desmarestiaceae. It is critically endangered, possibly extinct, and one of only fifteen protists evaluated by IUCN. Endemic to the Galápagos Islands, the specific epithet tropica alludes to its tropical habitat, rare for members of Desmarestiales. The common name acidweed applies to members of the genus Desmarestia, generally characterized by fronds containing vacuoles of concentrated sulfuric acid, but it is unclear if this species also produces acid.
Desmarestia aculeata is a species of brown algae found worldwide. Its common names include color changer, Desmarest's flattened weed, and sea sorrel, though the last name can refer to other species of Desmarestia.
Desmarestia ligulata is a species of brown algae found worldwide. Its common names include color changer, Desmarest's flattened weed, and sea sorrel, though the last name can also refer to other species of Desmarestia.
Desmarestia anceps is a species of brown algae found in the Antarctic Peninsula.
Mary Wyatt (1789–1871) was a British botanist, phycologist and retailer from Torquay, Devon. She was the compiler of the respected Algae Danmoniensis - a collection, i.e. exsiccata, of seaweeds to which William Henry Harvey later considered his Manual of the British Algae (1841) a 'companion' work. Wyatt helped to fuel the Victorian 'seaweed craze' for collecting. The tongue twister 'She Sells Seashells on the Sea Shore' was possibly inspired by Wyatt and her close companion Amelia Griffiths, with whom she collected seaweed and sea shells in Devon.
