The plants portal
are a major group of life
forms and include familiar organisms
such as trees
, and green algae
. About 350,000 species
of plants, defined as seed plants
and fern allies
, are estimated to exist currently. As of 2004, some 287,655 species had been identified, of which 258,650 are flowering
and 15,000 bryophytes
. Green plants
, sometimes called metaphytes
, obtain most of their energy from sunlight
via a process called photosynthesis
Aristotle divided all living things between plants (which generally do not move), and animals (which often are mobile to catch their food). In Linnaeus' system, these became the Kingdoms Vegetabilia (later Metaphyta or Plantae) and Animalia (also called Metazoa). Since then, it has become clear that the Plantae as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms. However, these are still often considered plants in many contexts, both technical and popular. Indeed, an attempt to perfectly match "plant" with a single taxon is problematic, because for most people the term plant is only vaguely related to the phylogenic concepts on which modern taxonomy and systematics are based.
is a genus
of 9 species of vespertine flowering plants
belonging to the family Solanaceae
. They are known as angel's trumpets
, sometimes sharing that name with the closely related genus Brugmansia
, and commonly as daturas. They are also sometimes called moonflowers
, one of several plant species to be so. Its precise and natural distribution is uncertain, owing to its extensive cultivation
throughout the temperate and tropical regions of the globe. Its distribution within the Americas
, however, is most likely restricted to the United States
, where the highest species diversity occurs.
All Datura plants contain tropane alkaloids such as scopolamine, hyoscyamine, and atropine, primarily in their seeds and flowers. Because of the presence of these substances, Datura has been used for centuries in some cultures as a poison and as a hallucinogen. There can be a 5:1 toxin variation across plants, and a given plant's toxicity depends on its age, where it is growing, and the local weather conditions. This variation makes Datura exceptionally hazardous as a drug.
