Erythrina crista-galli is a flowering tree in the family Fabaceae, native to Argentina, Uruguay, 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 and bucaré, to name a few. In English it is often known as the Cockspur Coral Tree.
Erythrina crista-galli is a small tree, the girth of its trunk measuring 50 cm. Normally it grows 5–8 meters tall, although some individuals, such as in the Argentine provinces of Salta, Jujuy and Tucumán, can grow up to 10 m.
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 trees flower in the summer, from October to April in their native South America and from April to October in the northern hemisphere. 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 unicarpela gynoecium is welded between the stamens like a knife in its sheath.
The flowers are rich in nectar and get visited by insects, which usually have to crawl underneath the carina and thus pollinate the flowers. They are also popular with many hummingbirds
The tree's fruit is monocarpic and dry, of the legume type, and no more than a few centimeters in length. The chestnut-brown seeds are cylindrical in form and are arranged sparsely throughout the seedpod's interior. The seed germ contains hypogeous cotyledons - the seeds stay underground upon germination.
