Petersianthus Africanus
''Petersianthus'' is a genus of woody plant in the Lecythidaceae family first described as a genus in 1865 under the name ''Petersia''. This turned out to be an illegitimate homonym, meaning that it had already been used by someone else to refer to a very different plant. So the name of these species in the Lecythidaceae was changed to ''Petersianthus''. It is native to the Philippines and to parts of Africa. The following two species belong to this genus, with the basionyms of both taxa belonging to what is known today as the family Combretaceae. ;species # ' (syn.

Elmer Drew Merrill
Elmer Drew Merrill (October 15, 1876 – February 25, 1956) was an American botanist and taxonomist. He spent more than twenty years in the Philippines where he became a recognized authority on the flora of the Asia-Pacific region. Through the course of his career he authored nearly 500 publications, described approximately 3,000 new plant species, and amassed over one million herbarium specimens. In addition to his scientific work he was an accomplished administrator, college dean, university professor and editor of scientific journals.Archives of the Arnold Arboretum Early life Merrill and his twin brother, Dana T. Merrill, were born and raised in the small village of Auburn, Maine, East Auburn, Maine. They were the youngest of six children by Daniel C. Merrill and Mary (Noyes) Merrill. Merrill showed an early interest in natural history, collecting and identifying plants, birds' eggs, rocks, and minerals. In 1894 he entered the University of Maine with the intention of stu ...

Capparis
''Capparis'' is a flowering plant genus, comprising around 250 species in the family Capparaceae which is included in the Brassicaceae in the unrevised APG II system. These plants are shrubs or lianas and are collectively known as caper shrubs or caperbushes. ''Capparis'' species occur over a wide range of habitat in the subtropical and tropical zones. Plant description The leaves are simple, entire and rarely reduced. Flowers are bisexual, bracteates, axillary or supra-axillary, solitary or in rows, in racemes or umbels. Sepals and petals are 4 in number and are free. Stamens are many, ovary on a gynophore, 1-celled. Fruit is a berry, globose or ellipsoid. ''C. zeylanica'' L.

Capparaceae
The Capparaceae (or Capparidaceae), commonly known as the caper family, are a family of plants in the order Brassicales. As currently circumscribed, the family contains 33 genera and about 700 species. The largest genera are '' Capparis'' (about 150 species), '' Maerua'' (about 100 species), '' Boscia'' (37 species) and ''Cadaba'' (30 species). Taxonomy The Capparaceae have long been considered closely related to and have often been included in the Brassicaceae, the mustard family (APG, 1998), in part because both groups produce glucosinolate (mustard oil) compounds. Subsequent molecular studies support Capparaceae'' sensu stricto'' as paraphyletic with respect to the Brassicaceae. However ''Cleome'' and several related genera are more closely related to members of the Brassicaceae than to the other Capparaceae. These genera are now either placed in the Brassicaceae (as subfamily Clemoideae) or segregated into the Cleomaceae. Several more genera of the traditional Capparaceae ar ...

Woody Plant
A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. In cold climates, woody plants further survive winter or dry season above ground, as opposite to herbaceous plants that die back to the ground until spring. Characteristics Woody plants are usually either trees, shrubs, or lianas. These are usually perennial plants whose stems and larger roots are reinforced with wood produced from secondary xylem. The main stem, larger branches, and roots of these plants are usually covered by a layer of bark. Wood is a structural tissue that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants. Woody plants, like herbaceous perennials, typically have a dormant period of the year when growth does not take place, in colder climates due to freezing temperatures and lack of daylight during the winter months, in subtropical and tropical climates due to the dry sea ...

Lecythidaceae
The Lecythidaceae comprise a family (biology), family of about 20 genera and 250–300 species of woody plants native to tropical South America, Africa (including Madagascar), Asia and Australia. The most important member of the family in world trade is the Brazil nut (''Bertholletia excelsa''), valued for its edible nut (fruit), nuts; the paradise nut (''Lecythis'' species) is also eaten. Taxonomy According to the most recent molecular analysis of Lecythidaceae by Mori ''et al.'' (2007), the three subfamilies are: *Foetidioideae (Foetidiaceae) from Madagascar include only ''Foetidia''. *Planchonioideae (including Barringtonia) are restricted to the Old World tropics. *Lecythidoideae (Lecythidaceae) are restricted to the New World tropics. Two other families are sometimes included in Lecythidaceae; the Scytopetalaceae and Napoleonaeaceae are hypothesized as most closely related to Lecythidaceae. The APG II system of 2003 includes genera from the family Scytopetalaceae in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basionym
In the scientific name of organisms, basionym or basyonym means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses. The term "basionym" is used in both botany and zoology. In zoology, alternate terms such as original combination or protonym are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an ''i''. Although "basionym" and "protonym" are often used interchangeably, they have slightly different technical definitions. A basionym is the ''correct'' spelling of the original name (according to the applicable nomenclature rules), while a protonym is the ''original'' spelling of the original name. These are typically the same, but in rare cases may differ. Use in botany The term "basionym" is used in botany only for the circumstances where a previous name exists with a useful description, and the '' International Code of Nomenclature for algae, fungi, and plants' ...

Combretaceae
The Combretaceae, often called the white mangrove family, are a family of flowering plants in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in ca 10 genera. The family includes the leadwood tree, ''Combretum imberbe''. Three genera, ''Conocarpus'', ''Laguncularia'', and ''Lumnitzera'', grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from ''Terminalia ivorensis''. The commonly cultivated ''Quisqualis indica'' is now placed in the genus ''Combretum''. Many plants in the Quisqualis species contain the Non-proteinogenic amino acid excitotoxin Quisqualic acid, a potent AMPA agonist.Excitotoxic cell death and delayed rescue in human neurons derived from NT2 cells, M Munir, L Lu and P Mcgonigl, Journal of Neuroscience, Vol 15, 7847–7860 White mangroves The family name comes from the type genus ''Combretum''; it also ...

Ericales Genera
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Ericales are a cosmopolitan order. Areas of distribution ...
