Semi-deciduous or semi-evergreen is a botanical term which refers to plants that lose their foliage for a very short period, when old leaves fall off and new foliage growth is starting. This phenomenon occurs in tropical and sub-tropical woody species, for example in Dipteryx odorata. [1] Semi-deciduous or semi-evergreen may also describe some trees, bushes or plants that normally only lose part of their foliage in autumn/winter or during the dry season, but might lose all their leaves in a manner similar to deciduous trees in an especially cold autumn/winter or severe dry season (drought).

Evergreen Plant that has leaves in all seasons

In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season.

Deciduous Trees or shrubs that lose their leaves seasonally

In the fields of horticulture and botany, the term deciduous means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit. The antonym of deciduous in the botanical sense is evergreen.

Sclerophyll Type of plant

Sclerophyll is a type of vegetation that has hard leaves, short internodes and leaf orientation parallel or oblique to direct sunlight that are adapted to long periods of dryness and heat that some types of vegetation present. The word comes from the Greek sklēros (hard) and phyllon (leaf). The term was coined by A.F.W. Schimper in 1898, originally as a synonym of xeromorph, but later was changed.

Tropical and subtropical dry broadleaf forests Biome

The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest.

Tropical and subtropical moist broadleaf forests Habitat type defined by the World Wide Fund for Nature

Tropical and subtropical moist broadleaf forests (TSMF), also known as tropical moist forest, is a tropical and subtropical forest habitat type defined by the World Wide Fund for Nature.

<i>Magnolia virginiana</i> Species of tree in the magnolia family, Magnoliaceae

Magnolia virginiana, most commonly known as sweetbay magnolia, or merely sweetbay, is a member of the magnolia family, Magnoliaceae. It was the first magnolia to be scientifically described under modern rules of botanical nomenclature, and is the type species of the genus Magnolia; as Magnolia is also the type genus of all flowering plants (magnoliophytes), this species in a sense typifies all flowering plants.

<i>Ziziphus</i> Genus of shrubs

Ziziphus is a genus of about 40 species of spiny shrubs and small trees in the buckthorn family, Rhamnaceae, distributed in the warm-temperate and subtropical regions throughout the world. The leaves are alternate, entire, with three prominent basal veins, and 2–7 cm (0.79–2.76 in) long; some species are deciduous, others evergreen. The flowers are small, inconspicuous yellow-green. The fruit is an edible drupe, yellow-brown, red, or black, globose or oblong, 1–5 cm (0.39–1.97 in) long, often very sweet and sugary, reminiscent of a date in texture and flavour.

Perennial plant Plant that lives for more than two years

A perennial plant or simply perennial is a plant that lives more than two years. The term is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials.

<i>Terminalia catappa</i> Species of plant

Terminalia catappa is a large tropical tree in the leadwood tree family, Combretaceae, native to Asia, Australia, the Pacific and Madagascar. Common names in English include country almond, Indian almond, Malabar almond, sea almond, tropical almond, beach almond and false kamani.

<i>Aesculus californica</i> Species of plant

Aesculus californica, commonly known as the California buckeye or California horse-chestnut, is a species of buckeye native to California and southwestern Oregon.

Marcescence Retention of dead plant organs that normally are shed

Marcescence is the retention of dead plant organs that normally are shed. Trees transfer water and sap from the roots to the leaves through their vascular cells, but in some trees as autumn begins, the veins carrying the sap slowly close until a layer of cells called the abscission layer completely closes off the vein allowing the tree to rid itself of the leaf. Leaf marcescence is most often seen on juvenile plants and may disappear as the tree matures. It also may not affect the entire tree; sometimes leaves persist only on scattered branches. Marcescence is most obvious in deciduous trees that retain leaves through the winter. Trees that exhibit marcescence are known as "everciduous". Several trees normally have marcescent leaves such as oak (Quercus), beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows (Salix). All oak trees may display foliage marcescence, even species that are known to fully drop leaves when the tree is mature. Marcescent leaves of pin oak complete development of their abscission layer in the spring. The base of the petiole remains alive over the winter. Many other trees may have marcescent leaves in seasons where an early freeze kills the leaves before the abscission layer develops or completes development. Diseases or pests can also kill leaves before they can develop an abscission layer.

Autumn leaf color phenomenon that affects the leaves during autumn

Autumn leaf color is a phenomenon that affects the normal green leaves of many deciduous trees and shrubs by which they take on, during a few weeks in the autumn season, various shades of yellow, orange, red, purple, and brown. The phenomenon is commonly called autumn colours or autumn foliage in British English and fall colors, fall foliage, or simply foliage in American English.

Woody plant Plant that produces wood and has a hard stem

A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. In cold climates, woody plants further survive winter or dry season above ground, as opposite to herbaceous plants that die back to the ground until spring.

Cuban dry forests

The Cuban dry forests are a tropical dry forest ecoregion that occupies 65,800 km2 (25,400 sq mi) on Cuba and Isla de la Juventud. The ecoregion receives 1,000–2,000 mm (39–79 in) of rainfall annually. Cuban dry forests can be differentiated into evergreen forests, semi-deciduous forests, mogotes, and sclerophyllous low forests.

Misanteca is an American flowering plant genus in the family Lauraceae. Mostly deciduous or evergreen tall trees. These trees have a resilient wood, useful as timber, for construction and as firewood.

Drought deciduous Plants that shed their leaves during periods of drought or generally in a dry season

Drought deciduous, or drought semi-deciduous plants refers to the plants that shed their leaves during periods of drought or generally in a dry season. This phenomenon is a natural process of plants and is caused due to the limitation of water around the environment where the plant is situated. In the spectrum of botany, deciduous is defined as a certain plant species that carry out abscission, the shedding of leaves of a plant or tree either by due to age or other factors that the plant regards these leaves to be useless or not worth keeping, over the course of a year. Deciduous plants can also be categorised differently other than due to drought or dry seasons, which can be temperate deciduous during cold seasons, and contrasted by evergreen plants which does not shed leaves and possess green leaves throughout the year.

<i>Ipomoea arborescens</i> Species of tree

Ipomoea arborescens, the tree morning glory, is a rapidly-growing, semi-succulent flowering tree in the family Convolvulaceae. This tropical plant is mostly found in Mexico, and flowers in late autumn and winter. Its common name in Nahuatl is Cazahuatl or Cazahuate.

Seasonal tropical forest

Seasonal tropical forest, also known as moist deciduous, semi-evergreen seasonal, tropical mixed or monsoon forests, typically contain a range of tree species: only some of which drop some or all of their leaves during the dry season. This tropical forest is classified under the Walter system as (ii) tropical climate with high overall rainfall concentrated in the summer wet season and dry season: representing a range of habitats influenced by monsoon (Am) or tropical wet savannah (Aw) climates. Drier forests in the Aw climate zone are typically deciduous and placed in the Tropical dry forest biome: with further transitional zones (ecotones) of savannah woodland then tropical and subtropical grasslands, savannas, and shrublands.

U.S. Virgin Islands Dry Forest

The U.S. Virgin islands dry forest is a sub-tropical dry forest spanning the United States Virgin Islands with varying degrees of coverage on each island. A dry forest is a habitat type defined by the World Wide Fund for Nature as being a predominantly deciduous forest located in a climate that is warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons which last several months. Dry forests can receive 850-1100mm of precipitation per year. In the case of the U.S. Virgin islands forest high quantities of sea salt from the ocean decreases the growth height of the trees, aiding in the creation of two canopy layers that are commonly found at an elevation below 300 meters. Additionally the unique wind pattern that the islands create may have added to this effect.
