Rivasmartinezia
''Rivasmartinezia'' is a genus of flowering plants belonging to the family Apiaceae. Its native range is Spain. The genus name of ''Rivasmartinezia'' is in honour of Salvador Rivas Martínez (1935–2020), who was a Spanish Biologist, Apothecary, Botanist (Mycology, Lichenology, Pteridology), also mountaineer and Alpinist. He was also Director of the Botanical Garden in Madrid. The genus was circumscribed In geometry, a circumscribed circle for a set of points is a circle passing through each of them. Such a circle is said to ''circumscribe'' the points or a polygon formed from them; such a polygon is said to be ''inscribed'' in the circle. * Circum ... by José Antonio Fernández Prieto and Eduardo Cires Rodríguez in Pl.

Apiaceae Genera
This is a list of genera belonging to the family Apiaceae. It contains all the genera listed by Plants of the World Online (PoWO) . A few extra genus names are included that PoWO regards as synonyms. Unless otherwise indicated, the placement of genera into sub-taxa is based on the taxonomy used by the Germplasm Resources Information Network (GRIN). "Not assigned" means either that the genus is unplaced in GRIN or that it is not listed by GRIN. Not assigned to a subfamily In a 2021 molecular phylogenetic study, the ''Platysace'' clade and the genera ''Klotzschia'' and ''Hermas'' fell outside the four subfamilies. It has been suggested that they could be placed in subfamilies of their own. *'' Hermas'' *'' Klotzschia'' *'' Platysace'' ;Others *'' Actinanthus'' *'' Adenosciadium'' *'' Agasyllis'' *'' Angoseseli'' *'' Apodicarpum'' *'' Asciadium'' *'' Austropeucedanum'' *'' Brachyscias'' *'' Caropodium'' *'' Caropsis'' *'' Chaetosciadium'' *'' Dactylaea'' *'' Deth ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apiaceae
Apiaceae () or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus ''Apium,'' and commonly known as the celery, carrot, or parsley family, or simply as umbellifers. It is the 16th-largest family of flowering plants, with more than 3,800 species in about 446 genus, genera,Stevens, P.F. (2001 onwards).APIACEAE Lindley, nom. cons. ''Angiosperm Phylogeny Website''.

Pteridology
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate ( Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and eusporangiates, is estimated to have originated in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpinist
Alpine climbing () is a type of mountaineering that uses any of a broad range of advanced climbing skills, including rock climbing, ice climbing, and/or mixed climbing, to summit typically large routes (e.g. multi-pitch or big wall) in an alpine environment. While alpine climbing began in the European Alps, it is used to refer to climbing in any remote mountainous area, including in the Himalayas and Patagonia. The derived term alpine style refers to the fashion of alpine climbing to be in small lightly equipped teams who carry their equipment (e.g. no porters), and do all of the climbing (e.g. no sherpas or reserve teams). Alpinists face a wide range of serious risks in addition to the specific risks of rock, ice, and mixed climbing. This includes the risks of rockfalls (common with rock faces in alpine environments), avalanches (especially in couloirs), seracs and crevasses, violent storms hitting climbers on exposed mountain faces, altitude effects (dehydration, edema, fro ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. For example, if we determine that species X, Y, and Z belong in genus A, and species T, U, V, and W belong in genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecu ...

José Antonio Fernández Prieto
José is a predominantly Spanish and Portuguese form of the given name Joseph. While spelled alike, this name is pronounced very differently in each of the two languages: Spanish ; Portuguese (or ). In French, the name ''José'', pronounced , is an old vernacular form of Joseph, which is also in current usage as a given name. José is also commonly used as part of masculine name composites, such as José Manuel, José Maria or Antonio José, and also in female name composites like Maria José or Marie-José. The feminine written form is ''Josée'' as in French. In Netherlandic Dutch, however, ''José'' is a feminine given name and is pronounced ; it may occur as part of name composites like Marie-José or as a feminine first name in its own right; it can also be short for the name ''Josina'' and even a Dutch hypocorism of the name ''Johanna''. In England, Jose is originally a Romano-Celtic surname, and people with this family name can usually be found in, or traced to, the ...
