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.
, commonly known as the New South Wales waratah
or simply waratah
, is a large shrub in the plant family Proteaceae
. It is a shrub to 3 or 4 m (10–13 ft) high and 2 m (7 ft) wide, with dark green leaves. Its several stems arise from a pronounced woody base known as a lignotuber
. The species is most renowned for its striking large red springtime inflorescences (flowerheads)
, each including hundreds of individual flowers
. These are visited by the eastern pygmy possum (Cercartetus nanus)
, birds such as honeyeaters (Meliphagidae)
, and various insects.
The floral emblem for its home state of New South Wales, Telopea speciosissima has featured prominently in art, architecture, and advertising, particularly since Australian federation. Commercially grown in several countries as a cut flower, it is also cultivated in home gardens, requiring good drainage yet adequate moisture, but is vulnerable to various fungal diseases and pests. A number of cultivars with various shades of red, pink and even white flowers are available. Horticulturists have also developed hybrids with T. oreades and T. mongaensis which are more tolerant of cold, shade, and heavier soils.
- 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.
