Crotalaria juncea, known as brown hemp, Indian hemp, Madras hemp, or sunn hemp, is a tropical Asian plant of the legume family (Fabaceae). It is generally considered to have originated in India.
Bebbia, common name sweetbush, is a genus of aromatic shrubs in the family Asteraceae.
Chondrilla juncea is a species of flowering plant in the family Asteraceae known by a number of common names, including rush skeletonweed, gum succory, devil's grass, and nakedweed. The plant is native to Europe, Asia, and North Africa, but it is known throughout most temperate regions of the world as an introduced species which is usually considered a noxious weed.
Dolichocarpus is a genus of lichens in the family Opegraphaceae. The genus was circumscribed by lichenologist Rolf Santesson in 1949, with Dolichocarpus chilensis assigned as the type species. This species, found in Chile, grows on cactus spines in a fog desert. For several decades the genus remained monotypic, until 2008 when André Aptroot added Dolichocarpus seawardii. This lichen, found on St Helena, forms large patches on wet, overhanging rock ledges.
Thamnolia is a genus of lichens in the family Icmadophilaceae. Members of the genus are commonly called whiteworm lichens.
Menegazzia enteroxantha is a species of foliose lichen found in Australia. It was first formally described as a new to science by Swiss botanist Johannes Müller Argoviensis in 1896, as a specis of Parmelia. Rolf Santesson transferred the taxon to genus Menegazzia in 1942.
Menegazzia globulifera is a species of foliose lichen found in New Zealand, Australia, and southern South America. It was formally described as a species new to science in 1942 by Swedish lichenologist Rolf Santesson. The type specimen was collected north of Lago Fagnano. The lichen is typically encountered as an epiphyte, but occasionally it has been recorded growing on rocks. Menegazzia globulifera contains usnic acid and lecanoric acid as major lichen products.
Menegazzia hollermayeri is a species of foliose lichen found in southern South America. It was first formally described as a new species in 1937 by Finnish lichenologist Veli Räsänen, who included it in genus Parmelia. The type specimen was collected from Chile by R. P. Atanasio Hollermayer, after whom the lichen is named. Rolf Santesson transferred the taxon to Menegazzia in 1942.
Menegazzia opuntioides is a species of foliose lichen from southern South America. It was first formally described as a new species in 1889 by Swiss botanist Johannes Müller Argoviensis, as a species of Parmelia. The type specimen was collected in the Strait of Magellan in southern Chile. Rolf Santesson transferred the taxon to the genus Menegazzia in 1942. Menegazzia opuntioides has also been recorded from Argentina.
Menegazzia pertransita is a species of foliose lichen in the large lichen family Parmeliaceae. It is found in New Zealand, Australia, and South America. The lichen was first formally described by Scottish physician and bryologist James Stirton in 1877 as Parmelia pertransita. Swedish lichenologist Rolf Santesson transferred it to the genus Menegazzia in 1942.
Menegazzia tenuis is a species of foliose lichen found in southern South America. It was formally described as a new species in 1942 by Swedish lichenologist Rolf Santesson. The type specimen was collected from Puerto Angosto The lichen contains atranorin, lichesterinic acid, and protolichesterinic acid as major lichen products.
Psathyrostachys juncea is a species of grass known by the common name Russian wildrye. It was formerly classified as Elymus junceus. It is native to Russia and China, and has been introduced to other parts of the world, such as Canada and the United States. Psathyrostachys juncea is a great source of food for grazing animals, as it has high nutrition value in its dense basal leaves, even in the late summer and autumn seasons. This species can grow and prosper in many harsh environments, making it an ideal candidate for improvement as it can grow in areas were farming is difficult. This species is a drought-resistant forage plant and can survive during the cool seasons. It is also a cross-pollinator and is self-sterile. This means that P. juncea cannot self-fertilize; it must find another plant of the same species with which to exchange gametes. Self-sterilization increases the genetic diversity of a species.
Vermilacinia ceruchoides is a fruticose lichen found on rock faces of cliffs or boulders, sometimes growing among mosses, usually near the ocean, ranging in distribution from Marin County, California to San Vicente on the northern peninsula of Baja California, and in the Channel Islands.
Machaerina juncea, commonly known as bare twig-rush or tussock swamp twig rush, is a sedge in the sedge family, Cyperaceae, that is native to Australia, New Zealand, and New Caledonia.
Carmichaelia juncea, the braided riverbed broom, is a species of New Zealand broom, a prostrate shrub in the family Fabaceae that is endemic to New Zealand. It is extinct over much of its former range, including the North Island.
Rolf Santesson (1916–2013) was a Swedish lichenologist and university lecturer. He was awarded the Acharius Medal in 1992 for his lifetime contributions to lichenology.
Leif Tibell is a Swedish lichenologist and Emeritus Professor at the University of Uppsala. He is known for his expertise on calicioid lichens. He was awarded the Acharius Medal in 2012 for lifetime achievements in lichenology.
Thamnolia papelillo is a species of whiteworm lichen in the family Icmadophilaceae. It was described as a new species in 2004 by Norwegian lichenologist Rolf Santesson. It is found in Peru, where it grows on grazed grass steppe. Until Santesson's publication, it had been considered a variety of Thamolia vermicularis. It differs from T. vermicularis in having flat and wide podetia and a distribution restricted to South America.
Xenonectriella subimperspicua is a species of lichenicolous fungus in the family Nectriaceae. It has been recorded from South America, Europe, and New Zealand.
