Borthwickia
''Borthwickia'' is genus of flowering plants, containing one species, ''Borthwickia trifoliata'' from Yunnan, China and Myanmar. The common name in Chinese is 节蒴木 (jie shuo mu). It is a shrub or small tree with evergreen trifoliate leaves, whitish flowers clustered at the tip of the branches, with many stamens, and thin, knobbly, drooping fruits with many small red seeds. Description ''Borthwickia'' is a fragrant, evergreen shrub or small tree of high. It has square, light green, later pale yellow branchlets, which are initially covered in dense, short, white hairs, which are lost in the older, cylindrical branches. Leaves are arranged with two on opposite sides of the branchlets, and consist of a usually long leaf stalk and three papery leaflets, each on a stalk of about long. The midveins are raised on the upper surface, flat on the lower surface, where they are also covered in dense white hairs. Each leaflet has seven to nine side veins on each side, and reticulate ...

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 ...

Resedaceae
Resedaceae is a family of mostly herbaceous dicotyledonous plants comprising 107 known species in 8 to 12 genera: *'' Borthwickia'' - 1 species, sometimes placed in its own family Borthwickiaceae *'' Caylusea'' - 3 species *''Forchhammeria'' - 10 species *''Homalodiscus'' - 2 species *'' Neothorelia'' - 1 species *''Ochradenus'' - 4 species *''Oligomeris'' - 3 species *''Randonia'' - 1 species *'' Reseda'' - ca 55 species *'' Sesamoides'' - 1 species *'' Stixis'' - 7 species *''Tirania'' 1 species Taxonomy Roman natural phylosopher Gaius Plinius Secundus or Pliny the Elder, who lived in the first century, is attributed to have used the name ''Reseda'' for the first time in writing. But he must have used it for another plant, because the medial effect of healing swellings and inflamations that he described, could not be reproduced from ''Reseda'' by later researcher. The British botanist Samuel Frederick Gray erected the family Resedaceae in 1821, based on the type genus ''Res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovary (botany)
In the flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals. The pistil may be made up of one carpel or of several fused carpels (e.g. dicarpel or tricarpel), and therefore the ovary can contain part of one carpel or parts of several fused carpels. Above the ovary is the style and the stigma, which is where the pollen lands and germinates to grow down through the style to the ovary, and, for each individual pollen grain, to fertilize one individual ovule. Some wind pollinated flowers have much reduced and modified ovaries. Fruits A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm. Because gymnosperms do not have an ovary but reproduce through double fertilization of unprotected ovules, they produce naked seeds that do not ...

Family (biology)
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 ...

Monotypic Taxon
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 ...

Tirania
''Tirania purpurea'', the sole species in genus ''Tirania'', is a species of climbing plant native to Asia. This genus is related to ''Forchhammeria'' and '' Stixis'', but the placement of these three is uncertain. They were placed in Capparaceae until DNA studies showed them to be more closely related to Resedaceae that to Capparaceae. They are sometimes placed in their own family Stixaceae, but since it is not yet clear whether they are from a clade, they are better left in Brassicales The Brassicales (or Cruciales) are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system.

Phyllotaxis
In botany, phyllotaxis () or phyllotaxy is the arrangement of leaf, leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic leaf#Arrangement on the stem, arrangements of leaves on a stem are opposite and alternate (also known as spiral). Leaves may also be Whorl (botany), whorled if several leaves arise, or appear to arise, from the same level (at the same Node (botany), node) on a stem. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same Node (botany), node), on opposite sides of the stem. An opposite leaf pair can be thought of as a whorl of two leaves. With an alternate (spiral) pattern, each leaf arises at a different point (node) on the stem. Distichous phyllotaxis, also called "two-ranked leaf arrangement" is a special case of either opposite or alternate leaf arrangement where the leaves on a stem are arranged in two vertical columns on opposite sides of t ...

Capsule (botany)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classifie ...
