The deciduous characteristic has developed repeatedly among woody plants. Trees include maple, many oaks and nothofagus, elm, beech, aspen, and birch, among others, as well as a number of coniferous genera, such as larch and Metasequoia. Deciduous shrubs include honeysuckle, viburnum, and many others.
Fossil conifers included many diverse forms, the most dramatically distinct from modern conifers being some herbaceous conifers with no woody stems. [6] Major fossil orders of conifers or conifer-like plants include the Cordaitales , Vojnovskyales , Voltziales and perhaps also the Czekanowskiales (possibly more closely related to the Ginkgophyta ).
Larches are deciduous conifers in the genus Larix, of the family Pinaceae (subfamily Laricoideae).Growing from 20 to 50 metres (65 to 165 feet) tall, [1] they are native to the cooler regions of the northern hemisphere, where they are found in lowland forests in the high latitudes, and high in mountains further south.
Evergreen and deciduous species vary in a range of morphological and physiological characters. Generally, broad-leaved evergreen species have thicker leaves than deciduous species, with a larger volume of parenchyma and air spaces per unit leaf area. [4] They have larger leaf biomass per unit leaf area, and hence a lower specific leaf area ...
The great majority of conifer genera and species are evergreen, retaining their leaves for several (2–40) years before falling, but unusual deciduous conifers occur in five genera (Larix, Pseudolarix, Glyptostrobus, Metasequoia and Taxodium), shedding their leaves in autumn and leafless through the winter.
Coniferous trees are the dominant plants of the taiga biome. Very few species, in four main genera, are found: the evergreen spruce, fir and pine, and the deciduous larch. In North America, one or two species of fir, and one or two species of spruce, are dominant.
A broad-leaved, broad-leaf, or broadleaf tree is any tree within the diverse botanical group of angiosperms that has flat leaves and produces seeds inside of fruits. It is one of two general types of trees, the other being a conifer, a tree with needle-like or scale-like leaves and seeds borne in woody cones. [1]
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones.
