Diversity of plants image version 5.png
Plants are a major group of life forms and include familiar organisms such as trees, herbs, shrubs, grasses, vines, ferns, mosses, and green algae. About 350,000 species of plants, defined as seed plants, bryophytes, ferns 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.

Selected article

Banksia spinulosa
Banksia spinulosa, the Hairpin Banksia, is a species of woody shrub, of the genus Banksia in the Proteaceae family, native to eastern Australia. Widely distributed, it is found as an understorey plant in open dry forest or heathland from Victoria to north Queensland, generally on sandstone though sometimes also clay soils. It generally grows as a small shrub to 2 metres (7 ft) in height, though can be a straggly tree to 6 metres (20 ft). It has long narrow leaves with inflorescences which can vary considerably in coloration; while the spikes are gold or less commonly yellowish, the emergent styles may be a wide range of colours–from black, purple, red, orange or yellow. Banksia spinulosa was named by James Edward Smith in England in 1793, after being collected by John White, most likely in 1792. He gave it the common name "Prickly-leaved Banksia", though this has fallen out of use. With four currently recognised varieties, the species has had a complicated taxonomic history, with two varieties initially described as separate species in the early 19th century. A fourth from the New England region has only recently been described. However there has been disagreement whether one, var. cunninghamii, is distinct enough to once again have specific status. The pre-eminent authority on Banksia, Alex George, concedes there is still more work to be done on the Banksia spinulosa complex.

Pulsatilla alpina, alpine pasqueflower, is an alpine plant found in the mountain ranges of central and southern Europe from central Spain to Croatia. It grows between 1,200 metres (3,900 ft) and 2,700 m (8,900 ft) above sea level, and is mildly toxic.
