Milkweed Family
The Asclepiadoideae are a subfamily of plants in the family Apocynaceae. Formerly, it was treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family. They form a group of perennial herbs, twining shrubs, lianas or rarely trees but notably also contain a significant number of leafless stem succulents. The name comes from the type genus ''Asclepias'' (milkweeds). There are 348 genera, with about 2,900 species. They are mainly located in the tropics to subtropics, especially in Africa and South America. The florally-advanced tribe Stapelieae within this family contains several relatively familiar stem succulent genera, such as ''Orbea'', ''Huernia, Stapelia'' and ''Hoodia''. They are remarkable for the complex mechanisms which they have developed for pollination, independently parallel to the unrelated Orchidaceae, such as the grouping of their pollen into pollinia. The "fragrance" (or odor) of the flowers, often called "carrion flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Huernia
The genus ''Huernia'' (family Apocynaceae, subfamily Asclepiadoideae) consists of perennial, stem succulents from Eastern and Southern Africa and Arabia, first described as a genus in 1810.Brown, Robert. 1810. On the Asclepiadeae 11 The flowers are five-lobed, usually somewhat more funnel- or bell-shaped than in the closely related genus ''Stapelia'', and often striped vividly in contrasting colors or tones, some glossy, others matte and wrinkled depending on the species concerned. Frequently the flowers are colored a variation of red, yellow or brown. To pollinate, the flowers attract flies by emitting a scent similar to that of carrion. The genus is considered close to the genera ''Stapelia'' and '' Hoodia''. Phylogenetic studies have shown the genus to be monophyletic, and most closely related to the genus '' Tavaresia'', and to a widespread branch of stapeliads comprising the genera '' Orbea'', ''Piaranthus'' and ''Stapelia''.P.

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 ...

Microloma Calycinum PICT2490
''Microloma'' is a small genus of ''Ceropegia''-like twiners and twiggy bushes occurring in mainly arid or fynbos regions in South Africa. They are generally undistinguished when not in bloom, but the flowers of most species are incongruously decorative. Overview ''Microloma'' Robert Brown (botanist, born 1773), R. Br. in Mem. Werner. Soc.1: 53, (1809), is a genus of herbaceous perennial plant, perennial, dicotyledonous plants. ''Microloma'' species were originally described as members of the genus Ceropegia, in the family (biology), family Asclepiadaceae, but Robert Brown (botanist, born 1773), Brown separated them and created a new genus, still in the family Asclepiadaceae. More recently the Asclepiadaceae have been reclassified as the Family (biology), subfamily Asclepiadoideae of the dogbane family Apocynaceae. Common names of ''Microloma'' species are various and regional; Manning mentions "wax creeper" and "melktou" (literally "milk-string", a curious name because the pl ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetics, phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in Taxonomy (biology), taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tre ...

Gilbert Thomas Burnett
Gilbert Thomas Burnett (15 April 1800 – 27 July 1835) was a British botanist. Life Burnett was the first professor of botany at King's College London, from 1831 to 1835. He was the author of ''Outlines of Botany'' (1835), and ''Illustrations of Useful Plants employed in the Arts and Medicine'', published posthumously and illustrated by his sister Mary Ann Burnett.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Pollinia
A pollinium (: pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen are well attached to one another, but in other orchids there are two halves (with two separate viscidia) each of which is sometimes referred to as a pollinium. Most orchids have waxy pollinia. These are connected to one or two elongate stipes, which in turn are attached to a sticky viscidium, a disc-shaped structure that sticks to a visiting insect. Some orchid genera have mealy pollinia. These are tapering into a caudicle (stalk), attached to the viscidium. They extend into the middle section of the column. The pollinarium is a collective term that means either (1) the complete set of pollinia from all the anthers of a flower, as in Asclepiadoideae, ( ...

Orchidaceae
Orchids are plants that belong to the family (biology), family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan distribution, cosmopolitan plants that are found in almost every habitat (ecology), habitat on Earth except glaciers. The world's species richness, richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla (genus), Vanilla'' (the genus of the Vanilla planifolia, vanilla plant), the type genus ''Orchis'', and many commonly cultivated plants s ...
