Young trees have a smooth, brown bark that becomes gray-black with rough scaly ridges as the tree matures. The leaves are alternate, simple and tardily deciduous, remaining on the tree until mid-winter; they are 3–12 centimeters (1 + 1 ⁄ 4 – 4 + 3 ⁄ 4 inches) long and 2–6 cm (3 ⁄ 4 – 2 + 1 ⁄ 4 in) broad, variable in shape, most ...
Chart illustrating leaf morphology terms. The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets). [1]
Its leaves are dotted with resin glands [2] [3] The leaf base is cordate (heart-shaped) [2] [3] [4] Young shoots are not hairy. [4] It is generally diploid (28 chromosomes) [2] Since many of these characteristics vary from tree to tree, ideally several of these characteristics should be noted before making a positive identification.
Most Catalpa are deciduous trees; they typically grow to 12–18 metres (40–60 ft) tall, with branches spreading to a diameter of about 6–12 metres (20–40 ft). They are fast growers and a 10-year-old sapling may stand about 6 metres (20 ft) tall. They have characteristic large, heart-shaped leaves, which in some species are three-lobed.
The leaves are deciduous, opposite (or whorled), large, heart shaped, 18–30 cm (7.1–11.8 in) long and 13–21 cm (5.1–8.3 in) broad, pointed at the tip and softly hairy beneath. [5] The leaves generally do not color in autumn before falling; instead, they either fall abruptly after the first hard freeze, or turn a slightly yellow-brown ...
Populus grandidentata is a medium-sized deciduous tree native to North America, found mostly in the northeastern United States and southeastern Canada. Leaves are similar to Populus tremuloides, but slightly larger and having larger teeth. [3] The leaves tremble in the wind as those of P. tremuloides do. Bark of younger trees is olive-green ...
Leaves of Ilex decidua. This is an upright shrub or small tree that is typically between 10 and 15 feet at maturity though it may grow larger provided partial shade. [2] [3] I. decidua grows many thin trunks and stems in a clumping fashion [3] If left un-managed it will develop a large spreading mound of foliage up to 30' in the wild.
Periods of leaf fall often coincide with seasons: winter in the case of cool-climate plants or the dry-season in the case of tropical plants, [19] however there are no deciduous species among tree-like monocotyledonous plants, e.g. palms, yuccas, and dracaenas. The hydrangea hirta is a deciduous woody shrub found in Japan. [citation needed]
