Ceropegieae
The Asclepiadoideae are a subfamily of plants in the family Apocynaceae. Formerly, they were 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 the relatively familiar stem succulent genera such as ''Huernia, Stapelia'' and ''Hoodia''. They are remarkable for the complex mechanisms they have developed for pollination, which independently parallel the unrelated Orchidaceae, especially in the grouping of their pollen into pollinia. The fragrance from the flowers, often called "carrion", attracts flies. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoodia
''Hoodia'' (; known locally as "ghaap" or "bobbejaanghaap") is a genus of flowering plants in the family Apocynaceae, under the subfamily Asclepiadoideae, native to Southern Africa. One species of ''Hoodia'' in particular, ''Hoodia gordonii'', has achieved a degree of fame and controversy, after being investigated for use as a possible appetite suppressant. Description The group was first described as a genus in 1844. Hoodia are stem succulents, described as "cactiform" because of their remarkable similarity to the unrelated cactus family. They have a branching, shrub-like form, and the largest species (''Hoodia parviflora'') can grow to the size of a tree — over in height. The flowers are extremely variable in size — from less than 1 cm, to almost 20 cm in diameter, depending on the species. Flowers appear in large numbers, always near the tops of the stems. Those of larger-flowered species (such as ''Hoodia gordonii'') are often a papery pink-tan colour, pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aidomene
''Asclepias'' is a genus of herbaceous, perennial plant, perennial, flowering plants known as milkweeds, named for their latex, a milky substance containing cardiac glycosides termed cardenolides, exuded where cells are damaged. Most species are toxic to humans and many other species, primarily due to the presence of cardenolides, although, as with many such plants, there are species that feed upon them (e.g. their leaves) and from them (e.g. their nectar). Most notable are Monarch butterfly, monarch butterflies, who use and require certain milkweeds as host plants for their Larva, larvae. The genus contains over 200 species distributed broadly across Africa, North America, and South America. It previously belonged to the family (biology), family Asclepiadaceae, which is now classified as the Family (biology), subfamily Asclepiadoideae of the dogbane family, Apocynaceae. The genus was formally described by Carl Linnaeus in 1753, who named it after Asclepius, the Greek god of he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 nondescript when not in bloom, but the flowers of most species are incongruously decorative. Overview ''Microloma'' R. Br. in Mem. Werner. Soc.1: 53, (1809), is a genus of herbaceous perennial, dicotyledonous plants . ''Microloma'' species were originally described as members of the genus Ceropegia, in the family Asclepiadaceae, but Brown separated them and created the new genus, still in the family Asclepiadaceae. More recently the Asclepiadaceae have been re-classified as the 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 plants do not in general produce latex). Other names include "wax twiner" and "bokhorinkies" (literally "little goat- or antel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending 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 hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
