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.
Larches are deciduous conifers in the genus Larix, of the family Pinaceae (subfamily Laricoideae).Growing from 20 to 45 metres (65 to 150 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.
Metasequoia glyptostroboides, the dawn redwood, is a fast-growing, endangered deciduous conifer.It is the sole living species of the genus Metasequoia, one of three genera in the subfamily Sequoioideae of the family Cupressaceae.
Metasequoia, Dawn redwood, is a genus of fast-growing coniferous trees, one of three species of conifers known as redwoods. The living species Metasequoia glyptostroboides is native to Lichuan county in Hubei province, China. Although the shortest of the redwoods, it grows to at least 165 feet (50 meters) in height.
Most conifers are monoecious, but some are subdioecious or dioecious; all are wind-pollinated. Conifer seeds develop inside a protective cone called a strobilus. The cones take from four months to three years to reach maturity, and vary in size from 2 to 600 millimetres (1 ⁄ 8 to 23 + 5 ⁄ 8 in) long.
The conifers, division Pinophyta, are one of 13 or 14 division level taxa within the Kingdom Plantae. ... Deciduous conifers (23 P) I. Individual conifers (9 C, 17 P) P.
Larix laricina is a small to medium-size boreal deciduous conifer tree reaching 15–23 m (49–75 ft) tall, with a trunk up to 60 cm (24 in) diameter. [5] The bark of mature trees is reddish, the young trees are gray with smooth bark. [6]
Pseudolarix is a genus of coniferous trees in the pine family Pinaceae containing three species, the extant Pseudolarix amabilis and the extinct species Pseudolarix japonica and Pseudolarix wehrii. Pseudolarix species are commonly known as golden larch, but are not true larches (Larix) being more closely related to Keteleeria, Abies and Cedrus.
