Populus lasiocarpa, commonly called the Chinese necklace poplar, is a species of poplar native to humid forests of China. It is closely related to Populus wilsonii , Wilson's poplar.
Populus lasiocarpa is known for its large leaves that may reach dimensions of 35 × 25 cm. The stalk reaches a length of 20 cm and the bottom sides of the leaves are very hairy. The buds have a length of 3 cm. Shoots are sturdy, angular and fluffy. The petals grow on 25 cm long catkins and produce round, woolly fruit. [2]
This species blooms from March to May with the fruits ripening from May to June. [3]
Wilson's poplar differs from it in that the former's leaves are not hairy underneath and are generally smaller with a flattened petiole and resinous buds. [2]
Populus lasiocarpa is a species of poplar in the family Salicaceae . It was first described by Daniel Oliver in 1890. [4]
There are two known varieties:
The native distribution of Populus lasiocarpa comprises the temperate zones of China including the provinces of Guizhou, Hubei, Shaanxi, Sichuan and Yunnan. [4] There it grows in species-rich forests on mountain slopes and river banks [3] in altitudes of 1,300 to 3,500 metres (4,300 to 11,500 ft). It prefers fresh to moist clay soil which is lightly basic to alkaline, on sunny locations. The species thrives in warm temperatures but is most often winter-hardy. [5]
The Chinese necklace poplar is an important log tree in its area of distribution. In Central Europe, the tree is often used as an ornamental plant but is of no distinct forestral importance. [6]
Populus is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar, aspen, and cottonwood.
Populus section Aigeiros is a section of three species in the genus Populus, the poplars. Like some other species in the genus Populus, they are commonly known as cottonwoods. The species are native to North America, Europe, and western Asia. In the past, as many as six species were recognized, but recent trends have been to accept just three species, treating the others as subspecies of P. deltoides.
Salix caprea, known as goat willow, pussy willow or great sallow, is a common species of willow native to Europe and western and central Asia.
Populus nigra, the black poplar, is a species of cottonwood poplar, the type species of section Aigeiros of the genus Populus, native to Europe, southwest and central Asia, and northwest Africa.
The balsam poplars are a group of about 10 species of poplars, indigenous to North America and eastern Asia, distinguished by the balsam scent of their buds, the whitish undersides of their leaves, and the leaf petiole being round in cross-section. They are large deciduous trees, 30–60 m tall, with leaves with a rounded base, pointed apex, and a whitish waxy coating on the underside of the leaf; this latter distinguishes them from most other poplars. The name is derived from the pleasant balsam smell of the opening buds and leaves in spring, produced by a sticky gum on the buds which also helps protect the buds from insect damage. The balsam poplars are light-demanding trees that require considerable moisture. Balsam poplars are tolerant of very cold conditions, occurring further north than other poplars except for the aspens. The poplars in Southern California are tolerant of 100 plus degree heat. They grow along dry washes and dry riverbed's. The dry washes and dry riverbeds will have flowing water when it rains sufficiently. Their leaves hang down and are at an edge to the sun. This may be another factor why they can take the high heat. Their leaves tremble in the slightest breeze like the quaking aspen
Populus alba, commonly called silver poplar, silverleaf poplar, or white poplar, is a species of poplar, most closely related to the aspens. It is native to a region spanning from the Atlas Mountains of Africa, through most of South and Central Europe, into Central Asia; it has been introduced to many temperate, moist regions worldwide. It grows in moist sites, often by watersides, in regions with hot summers and cold to mild winters.
Salix babylonica is a species of willow native to dry areas of northern China, but cultivated for millennia elsewhere in Asia, being traded along the Silk Road to southwest Asia and Europe.
Populus deltoides, the eastern cottonwood or necklace poplar, is a species of cottonwood poplar native to North America, growing throughout the eastern, central, and southwestern United States as well as the southern Canadian prairies, the southernmost part of eastern Canada, and northeastern Mexico.
Populus tremula is a species of poplar native to cool temperate regions of the Old World.
Populus fremontii, commonly known as Frémont's cottonwood, is a cottonwood native to riparian zones of the Southwestern United States and northern through central Mexico. It is one of three species in Populus sect. Aigeiros. The tree was named after 19th-century American explorer and pathfinder John C. Frémont.
Prunus sibirica, commonly known as Siberian apricot, is a species of shrub or small tree native to northern China, Korea, Mongolia, and eastern Siberia. It is classified in the rose family, Rosaceae, and is one of several species whose fruit are called apricot, although this species is rarely cultivated for its fruit. The species was named by Carl Linnaeus in 1753.
Salix annulifera is a small shrub from the genus of the willow (Salix) with up to 8 centimeter long leaf blades. The natural range of the species is in China.
Salix calyculata is a low shrub in the willow genus Salix with mostly 8 to 15 millimeter long leaf blades. The natural range of the species is in China, Sikkim, and Bhutan. A distinction is made between two varieties.
Salix chienii is a large shrub or small tree in the willow genus Salix with initially light green and tomentose hairy and later reddish brown and balding branches. The leaf blades have lengths of 2 to 3.5 sometimes 5.5 centimeters. The natural range of the species is in China.
