Cordylanthus
''Cordylanthus'' (), commonly known as bird's beaks, is a genus of parasitic plants in the broomrape family, Orobanchaceae. These western North American natives are sparse, weedy-looking annuals with long branching erect stems and little foliage, and many bear bird's-beak–shaped flowers. They are remarkable among the broomrapes for growing at searing temperatures in arid climates. Taxonomy The first species known was '' Cordylanthus rigidus'', which was described as ''Adenostegia rigida'' in 1836 by the well-known English plant taxonomist George Bentham. Thomas Nuttall was another English botanist, an explorer of the former British colony, renamed the United States of America, and its recently acquired French territories to the west, as well as the Mexican and British lands of the far west, returning to England in 1841. In one of Nuttall unpublished manuscripts Bentham found another four species, which Nuttall had described using the name ''Cordylanthus'', despite this being ...

Cordylanthus Rigidus
''Cordylanthus rigidus'' is a species of flowering plant in the family Orobanchaceae known by the common name stiffbranch bird's beak. It is native to California and northern Baja California, where it grows in many types of habitat from coastal flats to high inland mountains. This is a hairy annual herb growing to maximum heights anywhere from 30 centimeters to 1.5 meters. There are at least four subspecies and possibly natural varieties not distinct enough to be considered subspecies. There is great variety in the appearance of the plant. The stem and foliage vary in color from greenish to yellows and reds; like other members of its family this species is a parasite on other plants so it does not rely entirely on green chlorophyll to produce its own nutrients. Its leaves are linear in shape and 1 to 4 centimeters long. The edges may roll in. The loose inflorescence produces solitary flowers on long stalks. Each hair-covered flower is shaped like a conical bird's beak with leaflik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicranostegia
''Dicranostegia'' is a monotypic genus of hemiparasitic flowering plants belonging to the family Orobanchaceae, containing the species ''Dicranostegia orcuttiana'', commonly known as Orcutt's bird's beak or Baja bird's beak. It is near-endemic to Baja California, found from Miller's Landing north to Tijuana, but has a few occurrences in southern San Diego County, California. It is differentiated among other similar species (like ''Cordylanthus'' spp.) in California by its leaves with 8 to 11 lateral lobes that are paired. It was formerly placed in the genus ''Cordylanthus'' until phylogenetic analysis led to it being split off. This species is threatened by the destruction of its habitat from urbanization. Description This annual hemiparasitic herb grows to in height and is green with dark-red markings, and often coated in stiff hairs. The roots are mostly yellowish in color, and form haustoria on their finer branches. The leaves are pinnately divided, arranged alternately, ...

Orobanchaceae
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera (e.g., ''Pedicularis'', ''Rhinanthus'', ''Striga'') were formerly included in the family Scrophulariaceae ''sensu lato''. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing '' Orobanche major'' and relatives, but neither ''Paulownia tomentosa'' nor ''Phryma leptostachya'' nor '' Mazus japonicus''. The Orobanchaceae are annual herbs or perennial herbs or shrubs, and most (all except ''Lindenbergia'', ''Rehmannia'' and ''Triaenophora'') are parasitic on the roots of other plants—either holoparasitic or hemiparasitic (fully or partly parasitic). The holoparasitic species lack chlorophyll and therefore cannot perform photosynthesis. Description Orobanchaceae is the largest of the 20–28 dicot fami ...

Scrophulariaceae
The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus ''Scrophularia'' L. Taxonomy In the past, it was treated as including about 275 genera and over 5,000 species, but its circumscription has been radically altered since numerous molecular phylogenies have shown the traditional broad circumscription to be grossly polyphyletic. Many genera have recently been transferred to other families within the Lamiales, notably Plantaginaceae and Orobanchaceae, but also several new families. - on linhere/ref> Several families of the Lamiales have had their circumscriptions enlarged to accommodate genera transferred from t ...

Richard Wettstein
__NOTOC__ Richard Wettstein (30 June 1863 in Vienna – 10 August 1931 in Trins) was an Austrian botanist. His taxonomic system, the Wettstein system, was one of the earliest based on phyletic principles. Wettstein studied in Vienna, where he was a disciple of Anton Kerner von Marilaun (1831-1898) and married his daughter Adele. He was a professor at the University of Prague from 1892, and at the University of Vienna from 1899. He newly laid out the Botanical Garden of the University of Vienna. In 1901 he became president of the Vienna Zoological-Botanical Society (''Zoologisch-Botanische Gesellschaft''), and during the same year took part in a scientific expedition to Brazil. In 1919 he was appointed vice-president of the Vienna Academy of Sciences. During his later years (1929–30), he traveled with his son, Friedrich, to eastern and southern Africa. The mycological genus ''Wettsteinina'' is named in his honor and also '' Wettsteiniola'', which is a genus of flowering plants ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Family (taxonomy)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

James Francis Macbride
James Francis Macbride (19 May 1892 16 June 1976) was an American botanist who devoted most of his professional life to the study of the flora of Peru. Early life and education Born on 19 May 1892 in Rock Valley, Iowa, Macbride graduated from the University of Wyoming in 1914 and worked briefly at the Gray Herbarium, Harvard University. Career In 1921, Macbride joined the staff of the Department of Botany at Field Museum of Natural History, Chicago, to head the nascent Flora of Peru program. Peru had been selected as the center of floristic research by C. F. Millspaugh, the Museum's first Curator of Botany. In 1922, Macbride and his assistant William Featherstone embarked on the first of two expeditions to Peru. They initially collected in the highland regions of the Departments of Lima, Junín, Huánuco, and Pasco. Macbride returned the following year to the Huánuco region and the Río Ucayali. For a decade from 1929, Macbride visited all the major herbaria of Europe to ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monograph
A monograph is a specialist work of writing (in contrast to reference works) or exhibition on a single subject or an aspect of a subject, often by a single author or artist, and usually on a scholarly subject. In library cataloging, ''monograph'' has a broader meaning—that of a nonserial publication complete in one volume (book) or a definite number of volumes. Thus it differs from a serial or periodical publication such as a magazine, academic journal, or newspaper. In this context only, books such as novels are considered monographs.__FORCETOC__ Academia The English term "monograph" is derived from modern Latin "monographia", which has its root in Greek. In the English word, "mono-" means "single" and "-graph" means "something written". Unlike a textbook, which surveys the state of knowledge in a field, the main purpose of a monograph is to present primary research and original scholarship ascertaining reliable credibility to the required recipient. This research is prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
