ovoid fruits, about 1 inch long, appear in clusters after flowers dis-
appear and turn black when mature.
 Ylang-ylang is not widely used; however, this tree is highly
recommended for its fall flowering habit and scented flowers. A rapid
growth rate is another factor in its favor since shade can be obtained
in a short time. Ylang-ylang is recommended for use as a framing
or shade tree and for its tropical effect.

 Carpinus caroliniana. Betulaceae. American Hornbeam or Blue
Beech. Central and Northern areas. Deciduous. Native.
 American hornbeam is common in moist hammocks in Northern
and Central Florida. This small tree has a rounded irregular crown
attaining a height of 30 feet with an 8- to 12-inch trunk. Thin, blue-
gray bark forms vertical ridges and channels and easily separates
this species from similar trees. Leaves are alternate, simple, ovate
to oblong, dark green, 2 to 4 inches long with double toothed margins.
Flowers are borne in 11/2-inch pendent, greenish catkins which appear
in early spring just as leaves appear.
 American hornbeam is ideally suited to low, moist, shady areas.
Trees can withstand some flooding without injury and serve well in
problem areas where water tables cannot be controlled. In the land-
scape they can be used as framing, patio and shade trees and in
informal gardens. Insects and diseases are not known to be a problem.

 Carya illinoensis. Juglandaceae. Pecan. Northern area. Decidu-
ous. United States and Mexico.
 Pecan normally attains 75 to 100 feet in height when mature with
large, ascending, symmetrical crowns. Leaves are alternate, pinnately
compound, with 11 to 17 oblong-lanceolate leaflets of a medium green
color. Fruit is the pecan, an edible nut.
 An occasional specimen is seen in central and southern Florida,
but there these trees do not fruit regularly. This large, wide-spread-
ing tree is ideal for summer shade and for its nuts. The pecan, where
soils are suitable, is ideally adapted where shade is wanted in summer
but not during winter months. Pecan is difficult to transplant but
grows rapidly once established. Leaves drop early in fall and are late
emerging in spring. Considerable care is required to control several
serious insect and disease pests, and zinc deficiency is also a serious
problem of pecans on many soils.

 Cassia spp. Leguminosae. Southern area and warmer parts of
Central area. Semi-evergreen.
 Species of the genus Cassia are among the most widely grown
flowering trees in southern Florida. Cassias are small trees with
large pinnate leaves and are prized for their flowers, which are pro-
duced in large masses. Most are tropical, but will withstand tempera-
tures as low as 25F for short periods of time. Diseases and insects
