Schoepfia
''Schoepfia'' is a genus of small hemiparasitic trees, flowering plants belonging to the family Schoepfiaceae. The genus has long been placed in the Olacaceae family. Description Plants in this genus are small trees or shrubs which exhibit heterostyly - individuals can have both often cylindrical brachystylous (short styled) flowers and somewhat bell-shaped dolichostylous (longer styled) flowers. In most plants where heterostyly occurs, there is a sexual differentiation between flower types, the brachystylous flowers being functionally male, or one type of flower is cleistogamous or self-fertile. In ''Schoepfia'' species both flowers are bisexual and can form fruit, the reason for two flower forms is mysterious. The flowers are fragrant and small. They arise from a short peduncle which grows from the leaf axils of a stem. The peduncle is subtended by persistent, imbricate perular bracts. The flower is subtended by a three-lobed epicalyx, it is composed of a bract and two b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schoepfia Arenaria
''Schoepfia arenaria'' is an extremely rare species of hemiparasitic flowering plant in the Schoepfiaceae family. It grows as a small, multi-trunked tree. It is endemic to Puerto Rico, where it is found growing along the northern coast. A local Spanish vernacular name recorded for this tree is ''araña'' ('spider'). It has no common name in English. Taxonomy ''Schoepfia arenaria'' was first collected near the small town of Santurce in 1899, immediately after the US had conquered Puerto Rico from the Spain and renamed the island Porto Rico. It grew here amongst other shrubs atop the higher sand dunes along the beach -although not stated as such, the derivation of the specific epithet is thus likely derived from the Latin word ''arena'', meaning 'sand'. There were three American plant collectors busy on the same beach that day, Amos Arthur Heller and his wife, Emily Gertrude, sent by the New York Botanical Gardens, and Charles Frederick Millspaugh from the Field Museum of Natural H ...

Schoepfiaceae
Schoepfiaceae is a family of flowering plants recognized in the APG III system of 2009. The family was previously only recognized by few taxonomists; the plants in question usually being assigned to family Olacaceae and Santalaceae. The genus ''Schoepfia'' is, according to molecular studies, more closely related to the families Misodendraceae and Loranthaceae, and to uphold the criteria of monophyly it must be excluded from Olacaceae. Further investigations have also shown that the South American genera ''Arjona'' and '' Quinchamalium'' (previously in the family Santalaceae) are part of this family. Thus the family contains three genera. ''Quinchamalium'' was thought to comprise 21 species in 2015, but this was reduced to a single widespread and morphologically variable species in that year. Christenhusz ''et al''. claimed there was a total of 58 known species in 2016, but for some reason counted 25 species of ''Quinchamalium'' and eight of ''Arjona''. *''Arjona'' Cavanilles (5 o ...

Schoepfia Californica
''Schoepfia californica'' is a species of flowering plant in the Schoepfiaceae commonly known as the California schoepfia, iguajil, and candelillo. It is a large shrub or small tree with grayish bark, smooth turquoise-colored leaves, and small red flowers. It is endemic to the Baja California peninsula, and is commonly found in desert flats, slopes, and washes in an area from the Bahia de Los Angeles to the Cape region at the tip of the peninsula. Description This species grows as a large shrub to small tree high. The branches are rigid and diverge widely, with the young branches minutely pubescent, while the older branches have smooth, grayish bark with white fissures. The leaves are arranged alternately, and are usually vertical due to a twist at their base. On the abaxial surface of the leaf are 3 faint ribs. The leaves are shaped obovate with smooth margins (not serrated), and covered with a glaucous layer, giving them a turquoise coloration. From February to April, sma ...

Klondike Mountain Formation
The Klondike Mountain Formation is an Early Eocene (Ypresian) geological formation located in the northeast central area of Washington state. The formation, named for the type location designated in 1962, Klondike Mountain north of Republic, Washington, is composed of volcanic rocks in the upper unit and volcanics plus lacustrine (lakebed) sedimentation in which a lagerstätte with exceptionally well-preserved plant and insect fossils has been found, along with fossil epithermal hot springs. The formation is the youngest in a group of formations which belong to the Challis Sequence rocks. The formation unconformably overlies rocks of the Eocene Sanpoil Volcanics and much older Triassic and Permian formations. The formation is bounded on its edges by a series of high-angle strike slip faults, which have contained the Klondike Mountain Formation in a series of graben structures, such as the Republic Graben. Public access to a fossiliferous outcrop at the north end of Republic is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olacaceae
Olacaceae is a family of flowering plants in the order Santalales. They are woody plants, native throughout the tropical regions of the world. , the circumscription of the family varies; some sources maintain a broad family, others split it into seven segregate families. Taxonomy The 1998 APG system and the 2003 APG II system assign it to the order Santalales in the clade core eudicots. Prior to the advent of molecular data, the circumscription of the family Olacaceae varied widely between different authorities.Valéry Malécot and Daniel L. Nickrent. 2008. "Molecular Phylogenetic Relationships of Olacaceae and Related Santalales". ''Systematic Botany'' 33(1):97-106. Among these various classifications, about 30 genera were included in the family. 15 genera are recognized for Olacaceae by the Germplasm Resources Information Network. The phylogenetic investigation published in 2008 recovered seven clades that were well-supported by molecular and morphological characters, but no for ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America).
