| − | '''Degeneriaceae''' is a [[Family (biology)|family]] of [[flowering plants]] [[endemic]] to [[Fiji]]. The [[APG IV system]] of 2016 (unchanged from the [[APG system]] of 1998, the [[APG II system]] of 2003 and the [[APG III system]] of 2009), recognizes this family, and assigns it to the order [[Magnoliales]] in the clade [[magnoliids]].{{r|APG3}}{{r|APG4}}
| + | {{inedible family}} |
| − | | |
| − | The family consists of only one genus, '''''Degeneria''''', which was named after [[Otto Degener]], who first found ''D. vitiensis'' in 1942. The ''Degeneria'' genus contains two species of trees in [[Fiji]]:
| |
| − | | |
| − | * ''[[Degeneria roseiflora]]'' <small>John M.Mill.</small> - [[Vanua Levu]], [[Taveuni]] - karawa
| |
| − | * ''[[Degeneria vitiensis]]'' <small>L.W.Bailey & A.C.Sm.</small> - [[Viti Levu]] - masiratu. This species appears on [[Fijian dollar|Fiji's five-dollar bill]].

| − | ==Floral structure==
| |
| − | The floral structure of ''Degeneria'' is unusual, considered to be primitive among the [[flowering plant]]s.{{r|Gifford}} The [[stamen]]s are similar to those in ''[[Austrobaileya]]'', ''[[Galbulimima]]'', and some [[Magnoliaceae]]; they do not have distinguishable anther, filament, and connective, but instead are leaf-like, with two pairs of microsporangia embedded in the surface. There are three veins, rather than the single vein in the stamen of most flowering plants.{{r|Gifford}} The [[gynoecium]] develops in an unusual way, similar to [[Winteraceae]], with laminal placentation, i.e., the young carpel is cup-shaped, and the [[ovule]]s develop on its upper surface. The margins of the carpel never fully fuse. A cleft remains filled with hairs, through which the pollen tubes grow towards the ovules.{{r|Gifford}}
