Selkirkia (plant)
''Selkirkia'' is a genus of flowering plants in the family (biology), family Boraginaceae. Three species occur on the South American mainland and one, ''Selkirkia berteroi'' (sometimes written ''berteri''), the first of the genus to be reported, is an endemism, endemic on Robinson Crusoe Island off the coast of Chile. It was previously considered a monotypic genus. Morphology ''Selkirkia'' species are perennial, either a shrub (''S. berteroi'') or decumbent, ascending or erect herbs to subshrubs. The leaves are ovate to lanceolate, and mostly occurring along the stem, not in rosettes. The corolla is white (''S. berteroi'') or blue to violet. The fruits consist of four nutlets, which are beset with barbed glochids, and superficially similar to the fruits of Cynoglossum, hound's tongues. The fruits of ''S. berteroi'' are somewhat winged and seemingly attached to the style but in fact, like the other three species, on a pyramidal gynobase. Distribution and conservation The four s ...

William Hemsley (botanist)
William Botting Hemsley (29 December 1843, in East Hoathly – 7 October 1924, in Kent) was an English botanist and 1909 Victoria Medal of Honour recipient. He was born in East Hoathly, Sussex and in 1860 started work at the Royal Botanic Gardens, Kew as an Improver, then Assistant for India in the Herbarium, finally Keeper of Herbarium and Library. He wrote a number of botanical works. In 1888, a genus of flowering plants from south-east Asia, belonging to the family Cucurbitaceae was named '' Hemsleya'' in his honour. He was elected a Fellow of the Royal Society Fellowship of the Royal Society (FRS, ForMemRS and HonFRS) is an award granted by the judges of the Royal Society of London to individuals who have made a "substantial contribution to the improvement of natural knowledge, including mathemat ... in June 1889.

Cynoglossum
''Cynoglossum'' is a genus of small-flowered plants in the family Boraginaceae (borage family). ''Cynoglossum officinale'', the common hound's-tongue, is a native of Asia, Africa, and Europe. It has been introduced into North America, and it is considered to be a troublesome weed because its burs stick to the wool of sheep and to other animals. Ingestion of this plant can also lead to photosensitivity in grazing In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to roam around and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other ... animals.

Omphalodes
''Omphalodes'' (navelwort) is a genus of flowering plants in the family Boraginaceae, widely distributed in the temperate Northern Hemisphere. In spring they produce blue or white flowers similar to forget-me-nots. Both the Greek ''Omphalodes'' (navel-like) and the English "navelwort" refer to the shape of the seeds. '' O. verna'' and cultivars of '' O. cappadocica'' are grown in gardens for their blue flowers which in spring appear above the leaves in loose sprays. They are woodland plants, preferring some shade. Systematics The genus ''Omphalodes'' traditionally contained many species that have been split-off in 2014 and 2016 The Japanese "''Omphalodes''" and "''Omphalodes scorpioides''" turned out not to be closely related to ''Omphalodes'', and were separated as distinct genera, ''Nihon'' and '' Memoremea'' respectively. Serrano et al. separated the Iberian annual species as '' Iberodes''. This left the remainder of species from Western Eurasia as sister to New World speci ...

Myosotidium Hortensia
''Myosotidium'' is a genus of plants belonging to the family Boraginaceae. This genus is represented by the single species ''Myosotidium hortensia'', the Chatham Islands lily, giant forget-me-not or Chatham Islands forget-me-not, which is endemic to the Chatham Islands, New Zealand. In the Maori language, it is known by the name kopukapuka. The biogeography is yet unresolved, but its ancestors may have originated from the American continent, as ''Myosotidium hortensia'' was found to be sister to the South American plant genus ''Selkirkia'' and both genera being sister to the North American genus ''Mimophytum''. ''Myosotidium hortensia'' is a fleshy herb In general use, herbs are a widely distributed and widespread group of plants, excluding vegetables and other plants consumed for macronutrients, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal ... with large orbicular somewhat fleshy leaves and appearingly parallel leaf ven ...

Selkirkia Pauciflora
''Selkirkia'' is a genus of predatory, tubicolous priapulid worms known from the Middle Cambrian Burgess Shale, Ogygopsis Shale and Puncoviscana Formation. 142 specimens of ''Selkirkia'' are known from the Greater Phyllopod bed, where they comprise 0.27% of the community. In the Burgess Shale, 20% of the tapering, organic-walled tubes are preserved with the worm inside them, whereas the other 80% are empty (or sometimes occupied by one or more small agnostid trilobites). Whilst alive, the tubes were probably vertical, whereas trilobite-occupied tubes are horizontal. Morphology ''Selkirkia'' had a body divisible into a proboscis towards the anterior of a trunk enclosed by a tube. The proboscis would have been partially invertable and was armed with several spinules and spines, decreasing size distally overall. It was controlled by at least two sets of anterior retractor muscles. Immediately behind the proboscis was the trunk, smooth for the most part but lined with papillae tow ...

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean.

Glochid
Glochids or glochidia (singular "glochidium") are hair-like spines or short prickles, generally barbed, found on the areoles of cacti in the sub-family ''Opuntioideae''. Cactus glochids easily detach from the plant and lodge in the skin, causing irritation upon contact. The tufts of glochids in the areoles nearly cover the stem surfaces of some cactus species, each tuft containing hundreds of glochids; this may be in addition to, or instead of, the larger, more conspicuous cactus spines, which do not readily detach and are not generally barbed. Mechanical irritant dermatitis Reaction to the glochidia Most cacti possess spines, some large enough to cause serious wounds. Glochids however, though smaller, commonly induce more troublesome, more persistent, dermatological manifestations in humans. Though minute, glochids commonly are barbed and once they have penetrated the skin barbed glochids are practically impossible to dislodge without leaving scraps of foreign material in ...
