| | Apocynaceae (from the genus Apocynum, the ancient name of the dogbane, from the Greek). DogBane Family. Fig. 49. Herbs, shrubs or trees with milky juice, often climbing: leaves opposite or whorled, rarely alternate, entire, exstipulate: flowers bisexual, regular; calyx 4-5-parted; corolla 4-5-lobed, hypogynous, gamopetalous, usually with appendages or folds in the throat, convolute or valvate; stamens 4-5, epipetalous, alternating with the corolla lobes; anthers usually sagittate and acute; pollen granular; hypogynous disk usually present and variously lobed; ovaries usually 2, rarely more or less united; mostly superior, each 1-celled, many-seeded, style 1, usually bearing a fleshy ring below the solitary stigma: fruit follicular with comose seeds, or indehiscent, or berry-like, or of nutlets, sometimes winged or prickly. | | Apocynaceae (from the genus Apocynum, the ancient name of the dogbane, from the Greek).

| | Many species of Landolphia yield commercial caoutchouc, as do also other genera, such as Urceola and Willoughbya. Some are very poisonous, e. g., Tanghinia of Madagascar; also Cerbera and Acocanthera. Tanghinia, the ordeal tree of Madagascar, "is the most poisonous of plants; a seed no larger than an almond suffices to kill twenty people." Death has followed the use of oleander wood as meat-skewers. An infusion of its leaves is an insecticide; of its bark, a rat-poison. Some are heart-poisons, for example Strophanthus and Aspidosperma (quebracho bark). The bark of Alstonia is a tonic. Allamanda cathartica is purgative. Several species furnish edible fruits tasting like citron. Wrightia tinctoria furnishes an indigo; W. tomentosa, a yellow dye. | | Many species of Landolphia yield commercial caoutchouc, as do also other genera, such as Urceola and Willoughbya.

| |
| − | The '''Apocynaceae''' or '''dogbane family''' is a family of [[flowering plant]]s, including [[tree]]s, [[shrub]]s, [[herb]]s, or [[liana]]s.
| |
| − |
| |
| − | Many species are tall trees found in the tropical [[rainforest]], and most are from the [[tropic]]s and subtropics, but some come from tropical dry, xeric environments. There are also some [[perennial plant|perennial]] herbs from [[temperate zone]]s. Many of these plants have milky sap; and many species are poisonous if ingested. Some genera of Apocynaceae, such as ''Adenium'' however, have either clear and milky, latex sap, and others, such as ''Pachypodium'', always have clear sap.
| |
| − |
| |
| − | ==Taxonomy==
| |
| − | The family, as currently recognized, includes some 1500 species divided in about 424 genera. The family [[Asclepiadaceae]] is now, according to [[Angiosperm Phylogeny Group|AGP II]] included in the '''Apocynaceae''' (Endress & Bruyns, 2000).
| |
| − |
| |
| − | There are five subfamilies:
| |
| − | *[[Rauvolfioideae]]
| |
| − | *[[Apocynoideae]]
| |
| − | *[[Periplocoideae]]
| |
| − | *[[Secamonoideae]]
| |
| − | *[[Asclepiadoideae]]
| |
| − |
| |
| − | The former two sub-families were part of the Apocynaceae ''sensu stricto'', whilst the latter three sub-families used to belong to the Asclepiadaceae. The Apocynaceae is the result of a conflation of the two families.

| |
| − | ==Distribution==
| |
| − | [[Image:Flower-01-KayEss-1.jpeg|thumb|''Wrightia antidysenterica'']]
| |
| − | Species in this family are distributed mainly in tropical regions:
| |
| − | *In the rainforests and swamps of India and Malaya: small to very tall evergreen trees, often with buttress roots, such as ''[[Alstonia]]'' and ''[[Dyera]]''.
| |
| − | *In northern Australia: small evergreen trees such as ''[[Cerbera]]'' and ''[[Ochrosia]]''.
| |
| − | *In deciduous forests of Africa and India: smaller trees such as ''[[Carissa]]'', ''[[Wrightia]]'' and ''[[Holarrhena]]''.
| |
| − | *In tropical America, India, Myanmar and Malaya: evergreen trees and shrubs, such as ''[[Rauwolfia]]'', ''[[Tabernaemontana]]'' and ''[[Acokanthera]]''.
| |
| − | *In Central America: ''[[Plumeria]]'', or the frangipani, with its waxy white or pink flowers and a sweet scent.
| |
| − | *In South America, Africa and Madagascar: many [[liana]]s such as ''[[Landolphia]]''.
| |
| − | *In the Mediterranean region: ''Nerium'', with the well-known [[oleander]] or Be-still tree (''Nerium oleander'').
| |
| − | *The only genera found in temperate [[Europe]] away from the Mediterranean are ''[[Vinca]]'' (Apocynoideae) and ''[[Vincetoxicum]]'' (Asclepiadoideae).
| |
| − | *In North America: ''[[Apocynum]]'', dogbane or Indian hemp, including ''[[Apocynum cannabinum]]'', a traditional source of fiber.
| |
| − | *In continental southern Africa (Angola, Botswana, Mozambique, South Africa, Swaziland, and Zimbabwe) and Madgascar, except for the humid evergreen forest of the eastern side of Madgascar, and never above 2000 m for the entire island: ''[[Pachypodium]]''.
| |
| − |
| |
| − | ==Characteristics==
| |
| − | The [[leaf|leave]]s are simple, usually opposite and decussate, or whorled; lacking [[stipule]]s. [[Flower]]s are usually showy, radially symmetrical (''actinomorphic''), aggregated in cymose or racemose [[inflorescence]]s (rarely fasciculate or solitary). They are [[Perfect flower|perfect]] (bisexual), with a synsepalous, 5-lobed calyx. Inflorescences are terminal or axillary. The [[stamen]]s are inserted on the inside of the corolla tube. The [[ovary (plants)|ovary]] is usually superior.
| |
| − |
| |
| − | The fruit is a [[drupe]], a [[berry]], a [[capsule (fruit)|capsule]] or a [[follicle]].
