Quercus hypoleucoides, the Silverleaf Oak or the Whiteleaf Oak can normally be found west to Arizona, east to Texas, southwest of New Mexico, and south to Mexico. Quercus hypoleucoides, though usually seen as a shrub, can be found to be a full-sized tree 30 feet tall in areas where it receives lots of water. The Quercus hypoleucoides can be distinguished from other oaks by its lanceolate leaves which are dark green on top but silver white on the lower surface.

Description
The Quercus hypoleucoides produces its flowers in the spring as most plants do. It is grown in warm regions and used as an ornamental due to its unusual foliage. Its species name, hypoleucoides, means "white underneath" and also happens to be the main way that it is distinguished from other oak trees. This species has acorns which are eaten by both squirrels and birds and even at times by humans. However before it is safe for people to eat, the tannic acid must first be leached out.


 * Bark: Is dark gray in color. It is thin with shallow, lighter colored fissures and narrow ridges.


 * Twig: Reddish brown in color and are broadly triangular with a sharp point. Are slender to moderate, generally with white fuzz. The end buds are clustered.


 * Leaves: Are alternate, evergreen, simple, and narrowly oblong to lanceolate. They are usually 2 to 4 inches long, with edges revolute. Occasionally there are a few shallow teeth, a narrow pointed tip, and a leathery texture. Their color is usually a shiny yellow-green color on top and white or silvery on the bottom.


 * Fruits: Oblong acorn that is 1/2 to 3/4 inch long. The cap is scaly bowl-shaped and covers 1/3 of the nut which ripens in 1 (or 2 seasons), maturing in early fall.


 * Flowers: They are Monoecious. The male flowers form long drooping catkins that are yellow-green in color. The female flowers has very small spikes in leaf axils that appear with the leaves


 * Form: Though usually found as a shrub, given enough moisture it can become a medium sized tree that reaches up to 60 feet tall with a spreading round crown.

Distribution
The Silverleaf Oak is commonly found in moist canyons and on ridges. It also is found in coniferous forests and high elevated lands from 5,000 to 8,000 feet. Mountains of southern Arizona and New Mexico such as the Santa Catalina Mountains and the Chiricahua Mountains, for example, have a pin-oak woodland at an elevation roughly 5700 to 7200 feet. Here the Quercus hypoleucoides can be found as well as other species of oak trees such as the Quercus arizonica, Q. emoryi, and Q. rugosa.
