Mimophytum Alienum
''Mimophytum'' is a genus of flowering plants in the family (biology), family Boraginaceae. The species are native to 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, ''Mimophytum alienum, M. alienum'' and ''Mimophytum alienoides, M. alienoides'', there are two differently shaped fruits: two navel-like nutlets and two nutlets with flat wings. In three species, ''Mimophytum omphalodoides, M. omphalodoides'', ''Mimophytum benitomartinezii, M. benitomartinezii'', and ''Mimophytum richardsonii, M. richardsonii'', the wings ...

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 ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, 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 Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Glochid
Glochids or glochidia (: "glochidium") are hair-like spines or short prickles, generally barbed, found on the areoles of Cactus, 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 Spine (botany), 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 fore ...
