Mimophytum Alienum
''Mimophytum'' is a genus of flowering plants in the family Boraginaceae. The species occur in Northeastern Mexico and adjacent areas of Texas, United States. They are similar to the closely related genus ''Omphalodes'' but a distinct group. Morphology ''Mimophytum'' species are (sub-)perennial herbs, either with a rhizome or erect. The leaves have petioles and are heart-shaped or rhombic. They produce blue flowers similar to forget-me-nots. The fruits consist of four winged nutlets. The nutlet wing can be turned upwards, creating a navel-like shape, similar to the fruits of ''Omphalodes''. In two species, '' M. alienum'' and '' M. alienoides'', there are two differently shaped fruits: two navel-like nutlets and two nutlets with flat wings. In three species, '' M. omphalodoides'', '' M. benitomartinezii'', and '' M. richardsonii'', the wings of the navel-shaped nutlets are beset with small barbed glochidia. Systematics The barbed glochidia on the nutlet wing was a character that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jesse More Greenman
Jesse More Greenman (December 27, 1867 – January 20, 1951) was an American botanist. He specialized in tropical flora, with emphasis on plants from Mexico and Central America. He was an authority on the genus ''Senecio'' and noted for his work at the Missouri Botanical Garden. Life and career Greenman was born in North East, Pennsylvania. Greenman earned his baccalaureate from the University of Pennsylvania 1893, then became an instructor for a year. In 1894 he went to Harvard University studying and working in the Gray Herbarium until 1899 when he earned his master's degree. There he began a long association with Benjamin Lincoln Robinson. In 1901 he earned his Ph.D. from the University of Berlin. He then taught at Harvard from 1902–1905. In 1902 he married Anne Turner, who was born in 1875 and died in 1936. Subsequently, he worked as an assistant to the curator of the Department of Botany of the Natural History Museum in Chicago and as an Assistant Professor of Botany at th ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omphalodes Erecta
''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 specie ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

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 ...

Mimophytum Richardsonii
''Mimophytum'' is a genus of flowering plants in the family Boraginaceae. The species occur in Northeastern Mexico and adjacent areas of Texas, United States. They are similar to the closely related genus ''Omphalodes'' but a distinct group. Morphology ''Mimophytum'' species are (sub-)perennial herbs, either with a rhizome or erect. The leaves have petioles and are heart-shaped or rhombic. They produce blue flowers similar to forget-me-nots. The fruits consist of four winged nutlets.

Forget-me-nots
''Myosotis'' ( ) is a genus of flowering plants in the family Boraginaceae. The name comes from the Ancient Greek "mouse's ear", which the foliage is thought to resemble. In the northern hemisphere they are colloquially known as forget-me-nots or scorpion grasses. ''Myosotis alpestris'' is the official flower of Alaska and Dalsland, Sweden. Plants of the genus are commonly confused with Chatham Islands' forget-me-nots, which belong to the related genus ''Myosotidium''. Description The genus was originally described by Carl Linnaeus. The type species is ''Myosotis scorpioides''. ''Myosotis'' species are annual or perennial herbaceous flowering plants with pentamerous actinomorphic flowers with 5 sepals and petals. Flowers are typically 1 cm in diameter or less, flatly faced, coloured blue, pink, white or yellow with yellow centres and borne on scorpioid cymes. The foliage is alternate, and their roots are generally diffuse. They typically flower in spring or soon after th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
