The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Magnoliopsida is the Botanical name for a class of Flowering plants By definition the class will include the family Magnoliaceae, but its Piperales is a Botanical name for an order of Flowering plants It necessarily includes the family Piperaceae but otherwise has been treated variously Antoine Laurent de Jussieu ( April 12, 1748 - September 17, 1836) was a French Botanist, notable as the first to propose |
The Aristolochiaceae, or the Birthwort family, are a family of flowering plants with 8 genera and about 400 species belonging to the order Piperales. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group The type genus is Aristolochia L.
The Aristolochiaceae are magnoliids, a basal group of angiosperms which are not part of the large categories of monocots or eudicots. Aristolochia is a large Plant Genus with over 500 Species. Collectively known as birthworts, pipevines or Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991 to refer to a group of Flowering plants that had been called "tricolpates" or "non-Magnoliid
Some newer classification schemes, such as the Update of the Angiosperm Phylogeny Group, place the family Aristolochiaceae in the order Piperales, but it is still quite common, though superseded, for the Aristolochiaceae to be assigned their own order (Aristolochiales). The Angiosperm Phylogeny Group, or APG, refers to two international groups of systematic botanists who came together to try to establish a consensus view of the Piperales is a Botanical name for an order of Flowering plants It necessarily includes the family Piperaceae but otherwise has been treated variously
They are mostly perennial, herbaceous plants, shrubs, woody vines or even lianas. A perennial plant or perennial ( Latin per, "through" annus, "year" is a Plant that lives for more than A(n herb (ˈhɝb or /ˈɝb/ see pronunciation differences) is a plant that is valued for qualities such as medicinal properties flavor scent or the like A shrub or Bush is a horticultural rather than strictly botanical category of Woody plant, distinguished from a Tree A vine is any plant of Genus Vitis (the Grape plants or by extension any similar climbing or trailing plant The liana is any of various long-stemmed usually woody vines that are rooted in the soil at ground level and use trees as well as other means of vertical support to climb up to
The membranous, cordate simple leaves are spread out, growing alternately along the stem on leaf stalks. In Botany, a leaf is an above-ground Plant organ specialized for Photosynthesis. The margins are commonly entire. There are no stipules. In Botany, stipule ( Latin stipula: straw stalk is a term coined by Linnaeus
The bizarre flowers are large to medium-sized, growing in the leaf axils. A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also They are bilaterally or radially symmetrical.
Many members of Aristolochia and some of Asarum contain the toxin aristolochic acid, which discourages herbivores and is known to be carcinogenic in rats. Aristolochic acid is a Rodent Carcinogen found in the Aristolochia and Asarum Species, both in the Herbivory is a form of Predation in which an Organism, known as a herbivore, consumes principally Autotrophs ref name=Campbell>Campbell The term carcinogen refers to any substance Radionuclide or radiation that is an agent directly involved in the promotion of Cancer or in the fatation of its propagation Rats are various medium sized long-tailed Rodents of the superfamily Muroidea Aristolochia itself is carcinogenic to humans.

Pipevine swallowtail butterflies lay their eggs on pipevine (Aristolochia species), and the larvae dine on the plant but are not affected by the toxin, which then offers the adult butterfly protection against predators. A butterfly is an Insect of the order Lepidoptera. Like all Lepidoptera butterflies are notable for their unusual life cycle with a In most Birds and Reptiles an egg ( Latin ovum) is the Zygote, resulting from Fertilization of the Ovum. A larva ( Latin; plural larvae) is a juvenile form of Animal with indirect development, undergoing Metamorphosis (for example A toxin ( Greek:, toxikon, lit (poison for use on arrows is a Poisonous substance produced by living cells or organisms that is active at very low
