'''''Delonix''''' is a [[genus]] of [[flowering plant]]s in the family [[Fabaceae]], [[Family (biology)|subfamily]] [[Caesalpinioideae]].<ref name="6subfamilies">{{cite journal | author = The Legume Phylogeny Working Group (LPWG). | year = 2017 | title = A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny | journal = [[Taxon (journal)|Taxon]] | volume = 66 | issue = 1 | pages = 44–77 | doi = 10.12705/661.3| doi-access = free | hdl = 10568/90658 | hdl-access = free }}</ref>  It contains [[tree]]s that are native to [[Madagascar]] and [[East Africa]]. By far the best known species is the Royal Poinciana (''[[Delonix regia|D. regia]]'').
The name of the genus is derived from the [[Greek language|Greek]] words δηλος (''delos''), meaning "evident," and ονυξ (''onyx''), meaning "claw," referring to the [[petal]]s.<ref>{{cite book |url=https://books.google.com/books?id=NJ6PyhVuecwC |title=The Names of Plants |first=David |last=Gledhill |edition=4 |publisher=Cambridge University Press |isbn=978-0-521-86645-3 |year=2008 |page=137}}</ref> The common name, '''poinciana''', comes from a former genus of the same name in which the members of the current genus ''Delonix'' were classified along with plants now placed in the genus ''[[Caesalpinia]]''.

==Use==
These plants (collectively known as {{lang|mg|fengoky}} or {{lang|mg|fengoka}}) release brown resin lumps that can be dissolved to make glue, or sucked as edible sweets among the [[Malagasy peoples|Malagasy]]. Their seeds too are roasted and eaten as a snack in the south.<ref>{{cite journal |last1=Puy |first1=David J.
