Menyanthaceae
Menyanthaceae is a family of aquatic and wetland plants in the order Asterales. There are approximately 60-70 species in six genera distributed worldwide. The simple or compound leaves arise alternately from a creeping rhizome. In the submersed aquatic genus '' Nymphoides'', leaves are floating and support a lax, umbellate or racemose inflorescence. In other genera the inflorescence is erect and consists of one (e.g., '' Liparophyllum'') to many flowers. The sympetalous, insect-pollinated flowers are five-parted and either yellow or white. The petals are ciliate or adorned with lateral wings. Fruit type is a capsule. Species of Menyanthaceae are found worldwide. The genera '' Menyanthes'' and '' Nephrophyllidium'' grow only in the northern hemisphere, while '' Liparophyllum'' and '' Villarsia'' occur only in the southern hemisphere. '' Nymphoides'' species have a cosmopolitan distribution. Menyanthaceae species are of economic importance as ornamental water garden plants, ...

Asterales
Asterales ( ) is an Order (biology), order of dicotyledonous flowering plants that includes the large Family (biology), family Asteraceae (or Compositae) known for composite flowers made of Floret#floret, florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is Cosmopolitan distribution, cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly Herbaceous plant, herbaceous species, although a small number of trees (such as the ''Lobelia deckenii'', the giant lobelia, and ''Dendrosenecio'', giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on Morphology (biology), morphological and biochemical levels.

Nephrophyllidium
''Nephrophyllidium'' is a monotypic genus of aquatic flowering plants in the family Menyanthaceae. The sole species is ''Nephrophyllidium crista-galli''. They are wetland plants with basal reniform and crenate leaves. Flowers are five-parted and white, and the petals are adorned with lateral wings and a midline keel. ''Nephrophyllidium'' is most nearly related to '' Menyanthes'', which is very similar in habit. The genus name is derived from the kidney-shaped leaves ( = kidney and ''phyllon'' = leaf), and the specific epithet refers to the curled petal edges ( = cockscomb). ''Nephrophyllidium crista-galli'' is found in the Pacific Northwest of America, and in Japan, where it can be called subspecies ''japonicum'' (Franch.) Yonek. & H.Ohashi. ''Nephrophyllidium'' is commonly known as deer cabbage. The IAPT determined that a prior synonym for the genus, ''Fauria'' Franch., too closely resembled the genus ''Faurea'' (Proteaceae The Proteaceae form a family (biology), family ...

Nymphoides
''Nymphoides'', or floatingheart, is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily ''Nymphaea''. ''Nymphoides'' are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface. Flowers are sympetalous, most often divided into five lobes (petals). The petals are either yellow or white, and may be adorned with lateral wings or covered in small hairs. The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally paired flowers. Species of ''Nymphoides'' are sold as aquarium plants, including the "banana plant", '' N. aquatica'' and the "water snowflake", '' N. indica''. Species native to the United States are '' N. cordata'' in the northeast and '' N. aquatica'' in the southeast.

Capsule (fruit)
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 (multicarpellary) 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 ...

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 ...

Dioecy
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...

Heterostyly
Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and these traits are not continuous. The morph phenotype is genetically linked to genes responsible for a unique system of self-incompatibility, termed heteromorphic self-incompatibility, that is, the pollen from a flower on one morph cannot fertilize another flower of the same morph. Heterostylous plants having two flower morphs are termed " distylous". In one morph (termed "pin", "longistylous", or "long-styled" flower) the stamens are short and the pistils are long; in the second morph (termed "thrum", "brevistylous", or "short-styled" flower) the stamens are long and the pistils are short; the length of the pistil in one morph equals the length of the stamens in th ...
