Geobotanically, Missouri belongs to the North American Atlantic region, and spans all three floristic provinces that make up the region: the state transitions from the deciduous forest of the Appalachian province to the grasslands of the North American Prairies province in the west and northwest, and the northward extension of the Mississippi embayment places the bootheel in the Atlantic and ...
Cinchona (pronounced / s ɪ ŋ ˈ k oʊ n ə / or / s ɪ n ˈ tʃ oʊ n ə / [1]) is a genus of flowering plants in the family Rubiaceae containing at least 23 species of trees and shrubs. All are native to the tropical Andean forests of western South America.
It is fast-growing, insect- and disease-resistant, and drought-tolerant. [7] The species is adaptable to a very wide range of soil and site conditions, from moist to dry, acid to alkaline, and gravelly to heavy clay; and can grow in partial shade to full sun. [8] The 5-petaled, 6–8 mm (0.24–0.31 in) diameter flowers form in corymbs. [8]
If the tree is felled but the stump is left, it can grow back new stalks. [7] If the bark is removed and the xylem is exposed to the elements, the tree will grow the bark back. The tree can even grow back if roots that are left in the ground are larger than 2 cm in diameter. [8] It reproduces rapidly and spreads its seeds via wind.
The bark is dark grey to black, deeply furrowed ironbark on the trunk and larger branches, smooth white to grey on the thinnest branches. Young plants and coppice regrowth have lance-shaped to oblong or linear leaves that are 30–110 mm (1.2–4.3 in) long and 5–35 mm (0.20–1.38 in) wide.
It is a slow-growing tree which may reach 35 m (115 ft) tall [5] with a trunk up to 1 m (3 ft 3 in) in diameter. [citation needed] The bark is dark red-brown.The leaves are scale-like, 2–4 mm (0.079–0.157 in) long, blunt tipped (obtuse), green above, and green below with a white stomatal band at the base of each scale-leaf.
It is a deciduous shrub or small tree growing to 2–9 metres (7–30 ft) tall with a short crooked trunk and stout spreading branches; in the northern parts of its range, it is a shrub, becoming a small tree in the southern parts of its range. The bark is reddish-brown, very rough on old stems. The branchlets are red at first, then green ...
Populus deltoides is a large tree growing to 20–30 m (65–100 ft) tall and with a trunk up to 2.8 m (9 ft 2 in) diameter, one of the largest North American hardwood trees. The bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees.
