Bromeliaceae
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte ''Tillandsia'' species tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitcairnioideae
Pitcairnioideae is a subfamily of the bromeliad family, Bromeliaceae. Traditionally, it was a large subfamily, comprising all those species with winged or more rarely naked seeds. Molecular phylogenetic studies showed that traditional Pitcairnioideae was not monophyletic, and the subfamily was more narrowly circumscribed. , the Encyclopaedia of Bromeliads placed five genera in the subfamily. Members of the subfamily are found from the Andes to the coast of Brazil, with one genus ('' Fosterella'') found northwards to Mexico. Description Species in the subfamily Pitcairnioideae have fruits in the form of capsules with winged seeds. The petals are not joined together when the flowers open, and are usually large and conspicuous. Taxonomy Traditionally, the family Bromeliaceae was divided into three subfamilies based on the structure of the seeds and fruit, with Pitcairnioideae comprising all those with winged or rarely naked seeds. The other subfamilies were Bromelioideae and Til ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cottendorfia
''Cottendorfia'' is a genus of plants in the family Bromeliaceae. The genus name is for Johann Georg Freiherr Cotta von Cottendorf, German patron of the sciences (1796-1863). There is only one known species, ''Cottendorfia florida'', endemic to northeastern Brazil (Bahia and Piauí Piauí ( ) is one of the states of Brazil, located in the country's Northeast Region, Brazil, Northeast Region.

Sequencia
''Sequencia'' is a monotypic genus of plants in the family Bromeliaceae. The sole species is ''Sequencia serrata'' ( originally ''Brocchinia serrata''), endemic to the Vaupés region of Colombia. Formerly in the genus ''Brocchinia'', the genus was separated based on DNA sequence details (hence its name) and restriction site In molecular biology, restriction sites, or restriction recognition sites, are regions of a DNA molecule containing specific (4-8 base pairs in length) sequences of nucleotides; these are recognized by restriction enzymes, which cleave the DNA at ... characteristics.

Genera
Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstrate both monophyly and validity as a separate lineag ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Brewcaria
''Brewcaria'' is a genus of plants in the family Bromeliaceae. The genus is named for Charles Brewer-Carías, Venezuelan explorer and naturalist.

Lyman Bradford Smith
Lyman Bradford Smith (September 11, 1904 – May 4, 1997) was an American botanist. Smith was born in Winchester, Massachusetts. He studied botany during the 1920s at Harvard University and received his PhD from Harvard in 1930. Between 1928 and 1929, he worked for the first time in Brazil. Most of his life's work came to involve the taxonomy of the flowering plants of South America, in particular the bromeliads (''Bromeliaceae''). Smith worked on the Bromeliaceae for the North American Flora published by the American botanist Nathaniel Lord Britton, volume 19, no. 2 (1938). Smith was a world authority on '' Begoniaceae'' and also worked with '' Velloziaceae'' and numerous other plant families. He was a curator in the Smithsonian Institution's Department of Botany from 1947 until his retirement in 1974, but continued to work in the United States National Herbarium as an emeritus curator almost until his death in Manhattan, Kansas, in 1997.

Julian Alfred Steyermark
Julian Alfred Steyermark (January 27, 1909 – October 15, 1988) was a Venezuelan American botanist. His focus was on New World vegetation, and he specialized in the family Rubiaceae. Life and work Julian Alfred Steyermark was born in St. Louis, Missouri as the only child of the businessman Leo L. Steyermark and Mamie I. Steyermark (''née'' Isaacs). He studied at the Henry Shaw School of Botany at Washington University in St. Louis, where he completed his Ph.D. in 1933. His distinguished career included the Field Museum of Chicago, the ''Instituto Botánico'' of Caracas, and he was with the Missouri Botanical Garden in St. Louis from 1984 until his death. Steyermark's major works were his '' Flora of the Venezuelan Guayana'', ''Flora of Missouri'', and his ''Flora of Guatemala''. During his life, Steyermark collected over 130,000 plants in twenty-six countries, which earned him an entry in the '' Guinness Book of World Records''. He made the initial descriptions of 2,392 ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
