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.
, the green-ribbed sedge
, is a European species of sedge
with an Atlantic distribution. It is found from Fennoscandia
to the Iberian Peninsula
, and occurs in heaths
and other damp, acidic environments. It typically grows to a height of 15–120 cm (6–50 in), and has inflorescences
comprising one male and several female spikes
, each up to 45 mm (1.8 in) long. The utricles
have two conspicuous green veins, which give rise to both the scientific name
and the common name
of the species. In the vegetative state, it closely resembles C. bigelowii
, a species that usually grows at higher altitude. C. binervis
was first descrbed by James Edward Smith
in 1800, and is classified in Carex sect. Spirostachyae
; several hybrids
with other Carex
species are known.
Hypericum calycinum is a prostrate or low-growing shrub species of the genus Hypericum (Hypericaceae), indigenous to southeast Europe and southwest Asia. It is a low, creeping, woody shrub to about 1 m tall and 1–2 m wide. The solitary flowers are 3–5 cm in diameter, a rich yellow, with five petals and numerous yellow stamens.
- Describe all families, genera and species of the kingdom Plantae.
- For species, describe botanical properties, distribution, multiplication, usage (medicine, food, etc.), botanical history, cultivation information.
- Develop and implement a robust method of naming plant article for the ease of navigation and searching for Wikipedia users.
- Maintain Category:Plants and its subcategories.
