The tree is a large evergreen conifer growing to 30–45 metres (98–148 feet), exceptionally 72 m (236 ft) tall, [2] and with a trunk diameter of up to 1.2 m (3 ft 11 in), exceptionally 2.3 m (7 ft 7 in).
Christenhusz and colleagues (2011) included only one family in Pinales, Pinaceae, [2] a practice subsequently followed by the Angiosperm Phylogeny Website [33] and the Gymnosperm Database. [35] In this restricted model Pinales (Pinaceae) comprisea 11 genera and about 225 species, all of the other conifers originally included in this order ...
The female cones are large and usually woody, 2–60 centimetres (1–24 inches) long, with numerous spirally arranged scales, and two winged seeds on each scale. The male cones are small, 0.5–6 cm (1 ⁄ 4 – 2 + 1 ⁄ 4 in) long, and fall soon after pollination; pollen dispersal is by wind. Seed dispersal is mostly by wind, but some ...
The two-volume, extensively illustrated encyclopedia is a complete reference book covering all recognised conifer cultivars and species, both hardy and tropical. The 1,500-page work features names, synonyms, and brief descriptions, as well as information about height and spread after 10 years, where known, for over 8,000 cultivars and all 615 ...
Apart from two species in the yew family, all are in either the pine family (including firs, larches, spruces, pines, Douglas firs and hemlocks) or the cypress family (including junipers, redwoods, giant sequoias, bald cypresses and four genera of cedars). [2] [6] [7] [b] Softwood from North American conifers has a variety of commercial uses.
Conifers are the largest and economically most important component group of gymnosperms, but nevertheless they comprise only one of the four groups. The division Pinophyta consists of just one class, Pinopsida, which includes both living and fossil taxa. Subdivision of the living conifers into two or more orders has been proposed from time to time.
Podocarpus (/ ˌ p oʊ d ə ˈ k ɑːr p ə s / [2]) is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m (3 to 82 ft) tall, known to reach 40 m (130 ft) at times.
Cupressaceae is a widely distributed conifer family, with a near-global range in all continents except for Antarctica, stretching from 70°N in arctic Norway (Juniperus communis) [3] to 55°S in southernmost Chile (Pilgerodendron uviferum), further south than any other conifer species. [4]
