West Indian Almond - Terminalia catappa

The West Indian Almond - Terminalia catappa, is a deciduous tree that reaches heights of around 75 feet.  It grows in an erect form, generally with a single straight trunk sometimes becoming wider at the base with age.  It is easily identified in the Fall because of the large whorled leaves that become a bright crimson color in the fall.  Originally introduced from he West Indies but is cultivated and has become naturalized in hammocks and coastal areas of South Florida and the Florida Keys.  It is similar to Wild Almond (Terminalia arjuna), which is also naturalized in Southern Florida but the leaves are more or less oblong or oval rather then distinctively obvate.

The West Indian Almond has branches borne in whorls that are often drooping.  The bark is smooth and a steely gray when young, becoming scaled with age.  The leaves are alternate, crowded near branch tips in an almost umbrella like form.  The leaves are simple, leathery in texture, narrowing to a short point with margins along the entire leaf.  The upper leaf surface is dark green in color with obvious veining, becoming crimson in the fall.  The flowers are bisexual and unisexual, borne in an elongated spike from the leaf axis, occurring in the early summer each year.  Flowers are absent of petals, having 5 sepals and are green-white in color.  The fruit is a flattened, fleshy, almond shaped drupe, green when young becoming yellow and then finally red or blackish-green when ripe.  The fruit reaches sizes of 5 cm long and matures between late Fall to early Winter.

Deciduous Holly - Ilex decidua (Also known as Possumhaw Holly)

The Deciduous Holly (Ilex decidua) or Possumhaw Holly as it is more commonly known is a deciduous Holly tree that reaches heights of only 30 feet tall and grows in an ascending, erect or leaning fashion with a single or multiple trunks.  In open grown specimens the crowns are cylindrical in form and densely foliaged, while in forest grown specimens branches are few. The Possumhaw is native to the Eastern United States from Maryland in the north to Southern Florida in the South, West through Kansas and central Texas.  Most often located between 0-360 m in moist and wet woodlands, floodplains, bottoms, and occasionally dry uplands.  It is similar in appearance to the Carolina Holly but can be distinguished by elliptic rather than oblanceolate leaves.

It is a small deciduous tree or shrub that reaches heights of only 32 feet tall, generally growing in an erect form with a single upright trunk. Originally introduced from Mexico and Central/Southern America it has been cultivated and established in Southern Florida, especially in Key West.

The leaves of the Quickstick are alternate, pinnate, leaflets are in odd numbers between 7-15, ovate, elliptic or lanceolate in shape with a dull green upper surface that is a dull green in color. The flowers are bisexual, white or pink in color 1.5-2.2 cm long, inflorescence is a raceme occurring at the branch tips. Similar in appearance to the Black Locust, however the Black Locust has white flowers and smaller fruit, their ranges do not overlap so you will not see both in one area.
