A synsepal is a floral structure formed by the partial or complete fusion of two or more sepals. Such sepals are said to be gamosepalous.
It is common among Lady's Slipper orchids (Cypripedioideae) that the two lateral sepals are connate to form a synsepal in the outer whorl. This is located directly behind the pouch, opposite the upward-pointing dorsal sepal.
Synsepals may be bifid, i.e. divided into two equal lobes, or forked and divided in two by a deep cleft.
A sepal is a part of the flower of angiosperms. Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom.
Restrepia, abbreviated Rstp in horticultural trade, is a small genus of 50 species in the orchid family (Orchidaceae), closely related to Pleurothallis. Named in honor of Don Jose Restrepo, it tends to be more showy than most other Pleurothallids. They are found primarily at higher altitudes in the cool, damp montane forests of the Andes and Venezuela, with some into Central America up to southern Mexico.
Restrepia antennifera, the antennae-carrying restrepia, is an epiphytic, miniature species of orchid found at higher altitudes in cool, moist montane forests in Venezuela, Colombia, Ecuador and Peru.
Restrepia chocoensis is a species in the orchid family (Orchidaceae), named for the Department of Chocó, Colombia, where it was discovered.
Restrepia muscifera, commonly known as the fly-carrying restrepia, is a species of orchid.
A tepal is one of the outer parts of a flower. The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated, as in Magnolia, or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another. The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal".
In botany, the labellum is the part of the flower of an orchid or Canna, or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them.
Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts.
The perianth is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term perianth is derived from Greek περί and άνθος, while perigonium is derived from περί and γόνος . In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure.
Gynoecium is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of pistils and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes, the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells.
Lacistemataceae is a small flowering plant family. There are two genera:
Limnanthes, the type genus of the family Limnanthaceae, consists of annual herbaceous plants commonly known as the meadowfoams. The seven species are all native to coastal and adjoining regions of western North America, where they typically grow in marshy habitats, such as the margins of vernal pools. Some are endemic to California.
Paphiopedilum barbigerum is a species of flowering plant in the family Orchidaceae known commonly as the beard carrying paphiopedilum. It is native to China, Vietnam, and Thailand. It is an endangered species due to habitat destruction and overcollection for the horticultural trade.
Paphiopedilum dianthum is a species of flowering plant in the orchid family, Orchidaceae. It is native to China, Laos, and Vietnam. It is known commonly as the double flowered paphiopedilum.
Trisetella is a genus of orchids, native to Central and South America. Twelve of the 23 currently known species are endemic to Ecuador. They bear small flowers with fused sepals and fused petals. The synsepal bears three hair-like tails, which is the namesake of Trisetella.
Sclerosperma is a monoecious genus of flowering plant in the palm family found in Africa where three species are known. Having no obvious relatives, it does resemble the Madagascar native Marojejya though a detailed study of Madagascar's palms is required to determine if any true relationship exists. The lack of relatives, and its interesting qualities, indicate, at one time, the existence of a diverse African palm flora. The name is from two Greek words meaning "hard" and "seed".
This glossary of botanical terms is a list of definitions of terms and concepts relevant to botany and plants in general. Terms of plant morphology are included here as well as at the more specific Glossary of plant morphology and Glossary of leaf morphology. For other related terms, see Glossary of phytopathology, Glossary of lichen terms, and List of Latin and Greek words commonly used in systematic names.
Lepidobotryaceae is a family of plants in the order Celastrales. It contains only two species: Lepidobotrys staudtii and Ruptiliocarpon caracolito.
Bulbophyllum sect. Xiphizusa is a section of the genus Bulbophyllum. It is one of six Bulbophyllum sections found in the Americas.
In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
