It is in the Pinaceae family. However, the pines as a whole form a clear monophyletic unit and retention as a single genus remains the best treatment. In the past, crude pine resin had been used in sailing vessels as packing material and for waterproofing" (Moussouris and Regato 1999). subgenus Pinus, section Trifoliae (Duhamel), subsection Australes (Loudon). Pines are economically important for their timber, pulp, tar, and turpentine. Biodiversity of Pinus (Pinaceae) in Mexico: speciation and paleo-endemism. Pinus, the pines, is a genus of approximately 111 extant tree and shrub species. The sections and subsections presented here are mainly those of Gernandt et al. When sawn, sugar pine wood shows brown streaks from the resin canals in tree trunk. (2005), and Hernández-León et al. The portion of the cone scale that is exposed before the mature cone opens is thickened and is called the umbo; it may be unarmed, or armed with a spine or prickle; and it may be formed into a woody pyramid called an apophysis. Sci. 1 … Cones may have relatively stiff, woody scales (the norm in subgenus Pinus) or more flexible scales (subgenus Strobus). Ages of over 1000 years have been encountered in P. albicaulis, P. aristata, P. balfouriana, P. flexilis, and P. longaeva, all species native to western North America. This Family included Pines, Spruces and Firs. Written and researched by: Andy Brown. More books about trees at the Trees Bookstore.

Many species are very drought tolerant. American Journal of Botany 80(7):743-751. Source: see here (accessed 2001.12.25). A comparable ancient fossil pine is Pinus yorkshirensis, documented from a fossil cone preserved in the Wealden Formation in Yorkshire, UK; these sediments are about 130 million years old (Ryberg et al. Bailey (1970) provides a classic and still very useful treatment of the pines in subsection Balfourianae. 1967. 2009) which continue to confound understanding of large subsections such as Ponderosae. The number of leaves per fascicle, the length of needles, the number of sides of the needles (only Pinus monophylla has a round needle), the distribution of stomata (waxy white specks on the leaf surface), and the color and stiffness of the needles can all be useful characters for identification. 1986. Unlike characters of umbos of most species, characters of apophyses are much altered as the cone grows. P.49-68 in Richardson, D.M. Genome 42:893-908. ; Strobus Opiz), also called white or soft pines. – ocote chino P It also has medical properties and can be used as stimulant, antispasmodic, astringent, diuretic and anti-pathogenic. The oldest pine known is Pinus mundayi, a 2-needle pine described from fossil charcoal of the lower Cretaceous (ca. "Pine … Common names are from state and federal lists. Range maps have been published for the genus, many of its subsections and most of its species by Critchfield and Little (1966). Bailey, D. K. and F. G. Hawksworth. One is the eastern white pine (Pinus strobus). They continue to be a leading genus in agroforestry production, dominating plantations in the U.K. (P. contorta, P. nigra), New Zealand (P. radiata) and Brazil (P. elliottii). Shaw (1909, 1914) and Sudworth (1908), both of whom provide excellent drawings, though the taxonomy is inevitably very dated. Stone pines (P. armandii, P. gerardiana, P. pinea, and the species in subsection Cembroides) have an edible seed gathered by indigenous peoples (and sometimes commercially) and often comprising a major seasonal food source. // End -->. The shape and texture of the apophysis varies between species and is an important character for identification. The leaves ('needles') are in pairs, very stout (2 mm broad), up to 25 cm long, and bluish-green to distinctly yellowish-green. Comparable ages may occur in several old world species native to desert, arctic and alpine areas, but have not been demonstrated. Eastern White Pine (Pinus strobus L.) holds the title of the tallest native conifer in the Northeast. Extant species of Pinus are generally divided into two monophyletic subgenera, subgenus Strobus (haploxylon or soft pines), with one vascular bundle per leaf, and subgenus Pinus (diploxylon or hard pines), with two vascular bundles per leaf, and these morphological distinctions are confirmed based on plastid DNA sequence data (Geada-López et al., 2002; Gernandt et al., 2005). The interior structure of the leaf also may be important for identification, but this requires a microscope and so leaf anatomical characters are rarely used by field workers. There is a choice of different morphological characteristics on which to base classification and therefore (especially in the subgenus Pinus) some very different classification schemes. contorta growing in a peat bog on the Olympic Peninsula in Washington. Earle]. They have long been a principal source of timber for all purposes, including firewood, construction and woodworking. 2007. Willyard, Ann, Richard Cronn, and Aaron Liston. Volume 1 of the Flora of North America (Kral 1993) offers the following advice to those attempting to identify pine specimens: Native to all continents and some oceanic islands of the northern hemisphere, chiefly in boreal, temperate, or mountainous tropical regions; reaching its southernmost distribution shortly below the Equator in southeast Asia (Sumatra; P. merkusii). The Pinus genus is classified into three subgenera based on leaf characters, cone and seed. Graham, S.A. 1997. Washington, DC. Heart disease 5.

USDA Bulletin 460. About 74 species. 1993. Introduction. Univ. Each of the subgenera has been treated as a genus in its own right, and other subgenera have been proposed, but the great majority of morphological evidence, terpene data, and, more recently, molecular phylogenetic data have all firmly established the species composition and monophyletic origin of these two subgenera and the major sections within them. Some types of pine trees are native to the United States. Impact of the Eocene on the evolution of Pinus L. Annals of the Missouri Botanical Garden 80:471-498. (Farjon 1998). For a better understanding of morphology, please select #1. The bristlecone pine is the longest living species of plant on Earth, living for over 4,700 years. (2007) and Willyard et al. Phylogenetics of Pinus (Pinaceae) based on nuclear ribosomal DNA internal transcribed spacer region sequences. Pine pollen is used to promote healing and protect against a wide range of issues, including: 1. 2000. Pines include two subgenera, the typical pines in subgenus Pinus and the white pines in subgenus Strobus. Data collected thus far support the idea that the two subgenera are valid, clearly distinct, and are each monophyletic. Statistics are at the end of the page. Needles, of course, are the most common pine leaves. Pine is a coniferous tree in the genus Pinus, in the family Pinaceae. However, Pinus is one conifer genus that, despite its antiquity, shows ample evidence of ongoing speciation, and this makes it a very taxonomically complex group; see, e.g., Syring et al. Publ. by Eric Meier. Peattie (1950), one of the more 'literate' writers, a man not afraid to confess his love of great trees. These data also indicate that subgenus Strobus is probably of earlier derivation, with the species in section Parrya the most primitive in the genus. (2005) (amended to include subsection Attenuatae) and are based on their cladistic analysis using both character state and molecular phylogenetic data, as well as on molecular phylogenetic studies published by Liston et al. benthamiana), and the third-largest species is P. jeffreyi. 25-27.

To obtain resin commercially, a tapping cut is made in the pine bark and the resin drops are collected into buckets or bags. History of the maritime closed-cone pines, Alta and Baja California. There are about 111 species of pines worldwide, although different authorities accept between 105 and 125 species. Chloroplast DNA transgresses species boundaries and evolves at variable rates in the California closed-cone pines (Pinus radiata, P. muricata, and P.nbsp;attenuata). Oil of turpentine is also produced by pine resin distillation and is used for thinning and dissolving paint and varnish, as well as for shoe polish and sealing wax manufacturing. Cataphylls are alternate (helically arranged) non-chlorophyllous primary leaves produced on shoots; they are typically small, subulate or lanceolate, with erose-hyaline to ciliate margins, leaving a distinctive pattern when they fall off the shoot; they are often a useful character in identification. Cone scales lack a sealing band; seed wing is articulate to strongly adnate. (Fig. Relationships within the group are unclear, but cone morphology and molecular data suggest that. The seed may be wind-carried, in which case it is normally small and light with a wing longer than the seed; or it may be dispersed by animals (primarily birds of the family Corvidae, jays and their allies), in which case the seed is normally larger and heavier, and the wing may be reduced to inconspicuity. From Wikipedia, the free encyclopedia Pinus radiata, the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico (Guadalupe Island and Cedros island). jemail("earlecj", "gmail", "com"); Crossability and relationships of the closed-cone pines.

Two seeds at the base of the cone scale, winged, in some the wing vestigial; cotyledons (3)6-14(24). The chief economic value of pines is in the construction and paper -products industries, but they are also sources of turpentine, rosin, oils, and wood tars. Notes of the Royal Botanical Gardens Edinburgh 44:275-310. Trees in the Pine family are monoecious. Pinus pinaster is a medium-size tree, reaching 20–35 m tall and with a trunk diameter of up to 1.2 m, exceptionally 1.8 m..

Falcon-Lang, Howard J., Viola Mages, and Margaret Collinson. In many areas Pinus is a forest dominant, either early successional or longer-lived, persisting in the late successional forest. Cones scales may remain closed and sealed by resin long after cone maturity; such cones are adapted to open when the resin is melted by fire and are called serotinous. 1999. There are two leaf vascular bundles per needle. There are also groups within some the subsections that appear to be monophyletic (as noted in the table above). 1996.
