The Jamaica Dogwood
Icthyomethia Piscipula, A. S. Hitch.
The Jamaica dogwood is a West Indian tree that grows also in southern Florida and Mexico. It is one of the commonest tropical trees on the Florida West Coast from the shores of Bay Biscayne to the Southern Keys. The leaves are four to nine inches long, with leaflets three to four inches in length, deciduous, vivid green, making a tree fifty feet high an object of tropical luxuriance. Its beauty is greatly enhanced in May by the opening of the pink, pea-like blossoms that hang in drooping clusters a foot or more in length. The necklace-like pods are frilled on four sides with thin papery wings.
The wood of this tree is very durable in contact with water, besides being heavy, close-grained, and hard. It is locally used in boat-building, and for fuel and charcoal. All parts of the tree, but especially the bark of the roots, contain an acid drug of sleep-inducing properties. In the West Indies the powdered leaves, young branches, and the bark of the roots have long been used by the natives to stupefy fish they try to capture.
The Horse Bean
Parkinsonia aculeata, Linn.
The horse bean or retama, native to the valleys of the lower Rio Grande and Colorado River, is a small graceful pod-bearing tree of drooping branches set with strong spines, long leaf-stems, branching and set with many pairs of tiny leaflets.
The bright yellow, fragrant flowers are almost perennial. In Texas the tree is out of bloom only in midwinter. In the tropics, it is ever-blooming. The fruit hangs in graceful racemes, dark orange-brown in color, and compressed between the remote beans. As a hedge and ornamental garden plant, this tree has no equal in the Southwest. It is met with in cultivation in most warm countries.
