Example: Pin Oak -Quercus palustris Pin Oak Taxonomy Kingdom: Plantae (Plants) Phylum: Magnoliophyta (Angiosperms) Class: Rosopsida (Eudicot) Order: Fagales Family: Fagaceae (Beech) Genus: Quercus (Oak) Specie: Quercus palustris (Pin Oak) Phylum: Magnoliophyta (Angiosperms) The flowers, which are the reproductive organs of flowering plants, are the most remarkable feature distinguishing them from other seed plants. Flowers aid angiosperms by enabling a wider range of adaptability and broadening the ecological niches open to them. This has allowed flowering plants to largely dominate terrestrial ecosystems. Class: Rosopsida (Eudicot) Pin Oak flowering Eudicots and Eudicotyledons are terms introduced by Doyle & Hotton (1991) to refer to a monophyletic group of flowering plants that had been called tricolpates or non-Magnoliid dicots by previous authors. The term means, literally, "true dicotyledons" as it contains the majority of plants that have been considered dicotyledons and have typical dicotyledonous characters. The term "eudicots" has been widely adopted to refer to one of the two largest clades of angiosperms (constituting >70% of all angiosperms), monocots being the other. General Characteristics Pin oak is a moderately large tree with normal heights ranging from 70 to 90 feet with diameters between 2 and 3 feet. Trees reaching 120 feet tall with 5-foot diameters are occasionally encountered on good sites. The bark of this tree is smooth, reddish to grayish-brown during the juvenile period, becoming darker and shallowly fissured as the tree growth slows with age. The lower branches of pin oak are prostrate to descending, with smooth, slender, reddish-brown twigs. Clusters of pointed buds are located at the tips of twigs. Three to five inch alternate leaves have 5 to 7 points or lobes with bristled tips and U-shaped sinuses. The leaves change in color from a dark green to a deep scarlet red in fall. The leaves are deciduous but will usually persist on the tree into winter. They love the swamp! -The pin oak tree can typically be found in swampy, low lands of forested areas. It is very common to see it in seasonal standing water where no other oaks are growing. -It likes acidic soil which is common in the swampy spots of the forest. Identification -Pin oaks are easy to spot. The bark is relatively thin and does not have deep furrows like burr oak, or black oak. Sometimes it almost looks like a pin oak is growing right out of its bark. Identification (cont.) -The lower branches are often a tangled mess. They tend to die off as the tree grows taller, especially in a wooded area. -The lower branches grow in a downward direction any way so as they die (due to lack of light) it looks like they are surrounding the trunk. The middle branches grow horizontally while the upper branches grow in an upward direction. The leaves of the pin oak tree -The leaves of the pin oak tree are similar to the scarlet oak, except a little smaller. The pin oak leaf also has a "U-shaped" sinus (or area between the "fingers", or lobes). How it got its name -One might think that the pin oak gets it name from the "pinny" appearance of the leaves and branches. Actually the name comes from the practice years ago of "pinning together" the timbers of a barn. The tough and resilient branches of this tree worked nicely for this task. Pin Oak Fruit: (Acorns) An acorn (nut) matures at the end of the second growing season after flowering. Acorns are dispersed from September to early December. Pin Oak Wood The wood is generally marketed as red oak, but is of significantly inferior quality, being somewhat weaker, often with many small knots. The wood is hard and heavy and is used in general construction and for firewood. Autumn Colors Pin oak acorns are an important food for mallards and wood ducks during their fall migration. Pin and other bottom-land oaks are the primary tree species in bottom-land duck-hunting areas (greentree reservoirs) that are artificially flooded during the fall and winter to attract migrating waterfowl. Pin oak acorns are also an important food for deer, squirrels, turkeys, woodpeckers, and blue jays.
