may attain a height of 60 feet and a spread of 100 feet, they are best used in large areas or on wide residential streets where they should be 80 to 90 feet apart. Trees are useful in seaside and naturalistic plantings, in parks as a cover for picnic areas and in large formal lawn areas. Sand or twin live oak, Quercus virginiana maritimaa' is a smaller growing variety of the live oak, distinguished by a small trunk, branches and paired acorns borne on long stalks or peduncles. When available the twin live oak is recommended as a framing, background or shade tree. Laurel oak, Quercus laurifolia, is a semi-evergreen oak that loses about one-third of its leaves in the fall and the remainder just before new leaves comes out in spring (Fig. 49). Laurel oak has simple, thin oblong leaves up to 6 inches long, shiny above, and somewhat paler beneath. The laurel oak is a fast-growing tree that produces a sym- metrical oval to round crown to 100 feet in height. This oak tolerates most soil types except extremely wet ones, but is subject to mushroom root-rot and heart rot. This tree is useful as a lawn and park shade tree, for framing in naturalistic roadside and seaside plantings and as a street tree for streets of medium width. As street trees, they should be spaced 50 to 70 feet apart. The water oak, Quercus nigra, is deciduous, but holds its leaves until the first heavy frost or cold weather and breaks dormancy early in the spring. Leaves are obovate, 3-lobed at the tip and 1 to 3 inches long. This rapid-growing tree produces a conical to round crown and grows to a height of 80 feet with a diameter of 50 feet. Water oak is relatively easy to transplant and maintain and is adapted to a wide range of soil conditions. Trees are useful as lawn shade trees, framing, naturalistic and roadside plantings and as street trees for streets of medium width if planted 50 to 60 feet apart. Schinus terebinthifolius. Anacardiaceae. Brazilian Pepper-Tree, Florida Holly or Christmas Berry Tree. Southern and Central areas. Evergreen. Brazil. Brazilian pepper-tree is a small, bushy spreading tree that grows to 30 feet. It is often used as a large shrub. Compound leaves are 4 to 8 inches long, odd-pinnate, with 5 to 9 leaflets (Fig. 50). During winter months, this tree produces numerous clusters of small, bright red fruits, hence the names "Florida Holly" and "Christmas berry tree." The plant is dioecious-male and female flowers are produced on separate plants, and female plants should be selected for fruiting. When clusters of red fruit and leaves are cut, they soon dry, and when used in Christmas decorations should be coated with a wax emulsion to prevent drying and shriveling. Brazilian pepper-tree grows best in a well-drained soil, and needs full sun for best fruiting, although trees will tolerate partial shade. This tree is widely used as a barrier planting for large properties,
