The leguminous plant of which a twig is represented in the plate, is one of the handsomest productions of Key West, where I found it in full flower in the month of May. It reaches the height of twenty feet or more, and has a rather slender, but elegant stem, of which the wood is as brittle as that of our common acacias. The pods are eight or nine inches in length, and of the size of a swan's quill ; the seeds, which are dark-brown when ripe, glossy and globular, he at regular intervals. The deep green of the long pendulous leaves, and the bright red of the large papilionaceous flowers, form a beautiful contrast. Many of these trees were planted near the house of my friend Dr Benjamin Strobel, under whose hospitable roof the twig was drawn. I saw no plants of the species on any other Key.
