Description:

Flora Borinqueña Cassia grandis Caña fistula cimarron Pink Shower Family Caesalpiniaceae Senna Family Cassia grandis Linnaeus filius (the son) Supplementum Plantarum 230. 1781. A large tree, inhabiting relatively dry parts of southwestern Porto Rico, sometimes planted for shade and ornament; its hard strong, durable wood valued for cabinet work, and in construction, has become scarce. It grows naturally also in Jamaica, Cuba, Haiti and Santo Domingo, in continental tropical America, and has been planted in other West Indian islands. The tree is elegant when in bloom, profusely covered with clusters of pink or reddish flowers, unfolding after the leaves have fallen, or with the new ones as they appear; the large, long woody drooping pods are conspicuous and interesting. Cassia is an ancient name, taken up by Linnaeus, in 1753, as a genus. Many species of trees, shrubs and herbs have been included in it by authors, but recent studies indicate that most of these are better classified under other genera, and Cassia restricted to about 20 kinds of trees, natives of tropical and temperate regions. These have evenly pinnate leaves, and mostly large flowers in clusters. The 5 sepals are blunt, nearly alike; the 5 petals are also nearly alike, and clawed; there are usually 10 perfect stamens, the 3 lower ones with long filaments and large anthers. The pods are woody, elongated, drooping, partitioned between the seeds, and fall to the ground without opening. Cassia grandis (large) is a tree with maximum height of about 20 meters. The young twigs are hairy. The leaves, finely hairy all over, are from 15 to 30 centimeters long, with a glandless stalk from 2 to 6 centimeters long; the 8 to 20 pairs of leaflets are oblong, nearly stalkless, blunt, thin, and from 3 to 5 centimeters long. The flowers are many, in finely hairy, drooping or spreading clusters from 10 to 20 centimeters long, and borne on slender stalks 1 or 2 centimeters long; the blunt, ovate-oblong sepals are 6 or 8 millimeters long, the nearly round petals about 12 millimeters broad. The compressed-cylindric, woody pods, are from 40 to 90 centimeters long, transversely roughened. Cassia fistula, native of tropical Asia, is naturalized in Porto Rico.
