Clodoveo Carrión Mora
Clodoveo Carrión Mora (1883–1957) was a palaeontologist and naturalist who is regarded as the most prolific and erudite natural scientist of Ecuador of the 20th century. Early years Clodoveo Carrión was born in Loja, Ecuador as the second son of Manuel Alejandro Carrión Riofrío (Poet) and Filomena Mora Bermeo. Among his brothers are Hector Manuel (Poet), José Miguel (lawyer, sociologist, senator, rector of the Universidad Nacional de Loja) and Benjamín Carrión. Clodoveo attended a Catholic primary school La Salle and then a secular high school Colegio Bernardo Valdivieso. As a young man he recognised that he had no aptitude for the letters ---something rare in his family--- but rather for the natural sciences. To pursue his scientific education, Clodoveo travelled to Europe. He studied at the University of London and at the University of Manchester obtaining the title of Industrial Engineer. During his 10-year stay in Europe he also carried out many studies in Spain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loja, Ecuador
Loja (), formerly Loxa and fully City of the Immaculate Conception of Loja ( es, Ciudad de la Inmaculada Concepción de Loja), is the capital of Ecuador's Loja Province. It is located in the Cuxibamba valley in the south of the country, sharing borders with the provinces of Zamora-Chinchipe and El Oro, and with Peru in the south. Loja holds a rich tradition in the arts, and for this reason is known as the Music and Cultural Capital of Ecuador. The city is home to two major universities. The city has a population of about 181,000, and is situated 2060 m (6758 ft) above sea level. It has a mild Andean climate, ranging between 16 and 30 °C. The Pan-American Highway runs past Loja. History The city of Loja was colonized by Field Marshal Alonso de Mercadillo in 1548, and it is named for his hometown of Loja in Spain. Originally located near La Toma in the Catamayo canyon since 1546, the city was relocated to its present location (about 35 km east) after a ...

Santalales
The Santalales are an order of flowering plants with a cosmopolitan distribution, but heavily concentrated in tropical and subtropical regions. It derives its name from its type genus ''Santalum'' (sandalwood). Mistletoe is the common name for a number of parasitic plants within the order. Overview Many of the members of the order are parasitic plants, mostly hemiparasites, able to produce sugars through photosynthesis, but tapping the stems or roots of other plants to obtain water and minerals; some (e.g. ''Arceuthobium'') are obligate parasites, have low concentrations of chlorophyll within their shoots (1/5 to 1/10 of that found in their host's foliage), and derive the majority of their sustenance from their hosts' vascular tissues (water, micro- and macronutrients, and sucrose). Most have seeds without testae (seed coats), which is unusual for flowering plants. Classification The APG IV system of 2016 includes seven families. As in the earlier APG III system, it was ...

Urticales
Urticales is an Order (biology), order of flowering plants. Before molecular phylogenetics became an important part of plant taxonomy, Urticales was recognized in many, perhaps even most, list of systems of plant taxonomy, systems of History of plant systematics, plant classification, with some variations in Circumscription (taxonomy), circumscription. Among these is the Cronquist system (1981), which placed the order in the subclass (biology), subclass Hamamelidae , as comprising: * Barbeyaceae * Cannabaceae * Cecropiaceae * Moraceae * Ulmaceae * Urticaceae In the APG III system (2009), the plants belonging to this order, along with four other families, constitute the order Rosales. Cecropiaceae is no longer recognized as separate from Urticaceae. The families Ulmaceae, Cannabaceae, Moraceae, and Urticaceae form a clade that has strong Resampling (statistics), statistical support in phylogenetic analyses of DNA sequences.Shu-dong Zhang, Douglas E.

Dicotyledonae
The dicotyledons, also known as dicots (or, more rarely, dicotyls), are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this group. The other group of flowering plants were called monocotyledons (or monocots), typically each having one cotyledon. Historically, these two groups formed the two divisions of the flowering plants. Largely from the 1990s onwards, molecular phylogenetic research confirmed what had already been suspected: that dicotyledons are not a group made up of all the descendants of a common ancestor (i.e., they are not a monophyletic group). Rather, a number of lineages, such as the magnoliids and groups now collectively known as the basal angiosperms, diverged earlier than the monocots did; in other words, monocots evolved from within the dic ...

Monocotyledon
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots. Monocotyledons have almost always been recognized as a group, but with various taxonomic ranks and under several different names. The APG III system of 2009 recognises a clade called "monocots" but does not assign it to a taxonomic rank. The monocotyledons include about 60,000 species, about a quarter of all angiosperms. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. About half as many species belong to the true grasses ( Poaceae), which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridophyta
A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes. However, they do not form a monophyletic group because ferns (and horsetails) are more closely related to seed plants than to lycophytes. "Pteridophyta" is thus no longer a widely accepted taxon, but the term ''pteridophyte'' remains in common parlance, as do ''pteridology'' and ''pteridologist'' as a science and its practitioner, respectively. Ferns and lycophytes share a life cycle and are often collectively treated or studied, for example by the International Association of Pteridologists and the Pteridophyte Phylogeny Group. Description Pteridophytes (ferns and lycophytes) are free-sporing vascular plants that have a lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryophyte
The Bryophyta s.l. are a proposed taxonomic division containing three groups of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. Bryophyta s.s. consists of the mosses only. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. The bryophytes consist of about 20,000 plant species. Bryophytes produce enclosed reproductive structures (gametangia and sporangia), but they do not produce flowers or seeds. They reproduce sexually by spores and asexually by fragmentation or the production of gemmae. Though bryophytes were considered a paraphyletic group in recent years, almost all of the most recent phylogenetic evidence supports the monophyly of this group, as originally classified by Wilhelm Schimper in 1879. The term ''bryophyte'' comes . Terminology The term "Bryophyta" was first suggested by Braun in 1864. G.M. Smith placed this group between Algae and Pteridophyta. Features The d ...

Melochia Carrioni
''Melochia'' is a genus of flowering plants in the mallow family, Malvaceae. It comprises 54 species from the tropical and subtropical regions of the world, ranging from India eastwards through Malesia and the Pacific Islands to the Americas and the Caribbean. Some taxonomy books have placed genus ''Melochia'' in family ''Sterculiaceae,'' but ''Sterculiaceae'' is now generally considered obsolete as a taxonomic class. The name "Melochia" comes from the Arabic name Mulukhiyah which in Arabic means mallow plants of the genus ''Corchorus'' (including ''Corchorus olitorius'') which are cultivated as vegetables in Egypt (and elsewhere). The take-up of this Arabic ''Molokheya'' as a label for the ''Melochia'' mallow plants began with the Latin botanist Prospero Alpini (died 1617), who spent several years in Egypt in the 1580s, and Alpini's name was soon adopted by the botanists Johann Bauhin (died 1613), Caspar Bauhin (died 1624), and Johann Vesling (visited Egypt 1628; died 1649).L.
