What traits were used by Aristotle to divide plants into groups?

Answer by Captain Algae
Aristotle's student, Theophrastus, gets credit for the first plant
classification system. Theophrastus classified 500 plants mainly on habit as
trees, shrubs, subshrubs and herbs. He gave lesser importance to other
characters including life cycle duration (annual, biennial and perennial),
ovary position, type of inflorescence and corolla type. We still use these
differences in some plant classifications today.

Artistotle did make an animal classification scheme.

"Banksia grandis, commonly known as Bull Banksia, Giant Banksia or Mangite, is a common and distinctive tree in South West Western Australia.

"Bull Banksia usually grows as a tree between 5 and 10 metres high, but may attain heights of up to 15 metres. It is also found in the form of a stunted, spreading shrub, near the south coast and whenever it occurs among granite rocks. Its trunks are short, stout and often crooked, with the rough grey bark characteristic of Banksia. The leaves are very distinctive; they are very large, being up to 45 cm long and 11 centimetres wide, and consist of a series of triangular lobes that go right back to the prominent midrib. Shiny dark green on top, they have a soft white tomentum underneath. New growth is a paler lime green and very attractive. Flowering is in Summer. The large cylindrical flower spikes, which can reach up to 35 cm high, are yellow, with a cream style. The "cones" shed their old flower parts early, so do not have the hairy appearance of the "cones" of many other Banksia species. Old cones are often varnished or cut and the typical banksia species used in decorative woodwork.


"Banksia grandis, developing follicles, with new growth behindBull Banksia is common throughout south west Western Australia, occurring from Jurien (30°17′S) in the north, south to Cape Leeuwin (34°22′S) and east to Bremer Bay (34°23′S 119°22′S E). It has been found inland as far as Badgedup and Dongolocking Nature Reserve. It is very common on the lateritic soils of the Darling Range, where it forms an understory in Jarrah and Marri forests. It will grow on nearly all soils of the coastal sandplain, but is somewhat less common there." (Wikipedia)
