'''''Erythrina''''' is a genus of tropical and subtropical flowering trees in the Family [[Fabaceae]] and distributed in tropical and subtropical regions worldwide. The name '''coral tree''' is used for many of these trees. Many species of ''Erythrina'' have bright red flowers, and this may be the origin of the common name ([[Greek language|Greek]] ''ερυθρος''). However, the growth of the branches can resemble the shape of sea [[coral]], and this is an alternative source for the name. In [[horticulture]], the name "coral tree" is used to refer to any red-flowered member of the genus. Not all species of ''Erythrina'' have bright red flowers; the [[Wiliwili]] (''E. sandwicensis'') has extraordinary variation in its flower colour, with orange, yellow, salmon, green and white all being found within natural populations. This striking color polymorphism is likely unique in the genus.
There are about 130 [[species]] in the Genus ''Erythrina'', some of them well known, as they are used widely in the tropics and subtropics as street and park trees, especially in drier areas. Some, such as the bucares of Venezuela, are used as shade trees for coffee or cacao crops. They grow up to 30 meters in height.
Species include:
*''[[Erythrina americana]]''<ref>[http://books.google.com/books?id=te53VV5u8YMC&pg=RA1-PA124&lpg=RA1-PA124&dq=erythrina+alkaloids&source=web&ots=e5SBqn4GS7&sig=JdEQoIKcYwAM7N_cTUtCQNhl6Hc John Stephen Glasby, Dictionary of Plants Containing Secondary Metabolites, Published by CRC Press]</ref>
*''[[Erythrina caffra]]'' - Coastal Coral Tree (South Africa)
*''[[Erythrina crista-galli]]'' – Cockspur Coral Tree or Ceibo (South America)
*''[[Erythrina edulis]]'' – Basul (Andes)
*''[[Erythrina eggersii]]'' - Cock's-spur (Puerto Rico, U.S. Virgin Islands)
*''[[Erythrina flabelliformis]]'' – Kearney Coral Bean (Arizona, New Mexico)
*''[[Erythrina fusca]]'' - Gallito (New and Old World tropics)
*''[[Coral bean|Erythrina herbacea]]'' – Coral Bean (southeastern United States)
*''[[Erythrina humeana]]'' – Natal Coral Tree (South Africa)
*''[[Erythrina indica]]'' – Tiger Claw ([[Ryukyu Islands]])
*''[[Erythrina lysistemon]]'' – Common Coral Tree (South Africa)
*''[[Erythrina poeppigiana]]'' - Bucare Ceibo (Northern South America)
*''[[Erythrina mulungu]]'' ([[synonymy|syn.]] ''E. verna'') – Mulungu (South America)
*''[[Wiliwili|Erythrina sandwicensis]]'' – Wiliwili ([[Hawaii|Hawai‘i]])
*''[[Erythrina variegate]]'' Roluos tree ([[Cambodia]])
*''[[Erythrina variegata]]'' Tiger's Claw (tropical [[Asia]] and northern [[Australia]])
*''[[Erythrina verspertilio]]'' - Bat's wing coral tree, Been tree ([[Australia]])
All species of ''Erythrina'' have bean-like seed pods, except ''E. sykesii'' which is sterile. The seeds of over 40 of the species contain [[alkaloid]]s, and some of the Amazonian species are used for medicinal and other purposes by indigenous peoples.
''Erythrina'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including ''[[Endoclita|Endoclita damor]]'', ''[[Hypercompe|Hypercompe eridanus]]'' and ''[[Hypercompe|Hypercompe icasia]]''.
The Cockspur coral tree (''E. crista-galli'') is the national flower of [[Argentina]].
The Costal coral tree (''E. caffra'') is the official city tree of [[Los Angeles, California]] (where it is referred to simply as the "coral tree").
