Comments: La madera es liviana y blanda. Apta para producir pasta celulósica, la corteza es empleada como astringente en baños de asiento y baños de vapor para dolores de huesos. Contiene el alcaloide eritrina (muy afín al curari) que posee propiedades narcóticas y sedativas. Arbol melífero. Usado como ornamental (López and Little 1987). The logs, due to their lightness, are used in raft construction. The wood is also used in making wooden shoes, floats, stable floors, and for wide planks, while large canoes are dug out from the biggest trunks. The bark is a source of tanning material and flowers yield a dye (Record and Mell 1924). The wood is also used to make troughs, fishing rope buoys, beehive crates, flooring for grain storage sheds and stables and drafting boards (Santos 1987).
Erythrina crista-galli is a flowering tree in the family Fabaceae, native to Argentina, Uruguay, southern Brazil and Paraguay. It is widely planted as a street or garden tree in other countries, most notably in California (in the United States). It is known by several common names within South America: ceibo, seíbo (Spanish), corticeira (Portuguese) and the more ambiguous bucaré, to name a few. In English it is often known as the Cockspur Coral Tree.
This species characteristically grows wild in gallery forest ecosystems along watercourses, as well as in swamps and wetlands. In urban settings, it is often planted in parks for its bright red flowers.
Erythrina crista-galli is a small tree, the girth of its trunk measuring 50 cm (20 in). Normally it grows 5–8 m (16–26 ft) tall, although some individuals, such as in the Argentine provinces of Salta, Jujuy and Tucumán, can grow up to 10 m (33 ft).
The root is a taproot with nodules produced by nitrogen fixing bacteria. The bacteria live in symbiosis with the tree, facilitating the tree's absorption of nitrogen in return for organic substances which the bacteria need. The tree's trunk is woody with irregular, spiny branches. These branches form a layer without definite form[verification needed] and die after flowering.
The tree flowers in the summer, from October to April in their native South America and from April to October in the northern hemisphere. It Usually blooms from November to February The red flower, arranged in inflorescences of the raceme type, is pentameric, complete, and of bilateral symmetry. Its calyx is gamosepalous, like a little red thimble. The corolla, like that of other legumes like common beans, is butterfly-shaped; however, the largest petal, called the "standard", is arranged in the lower part. The two of the petals called "wings" are so small that they are practically hidden within the calyx. The remaining two petals partially fuse together on occasion and form the flower's keel or "carina"; this protects its reproductive organs. The androecium consists of ten stamens, one free and nine united by their filaments (gynostemial androecium). The unicarpel gynoecium is welded between the stamens like a knife in its sheath.
The tree's fruit is a legume, a dry pod a few centimeters in length derived from a single carpel and contains about 8-10 chestnut-brown bean-shaped seeds. The cotyledons are hypogeal, staying underground upon germination.
