In botany, a spadix (pronounced , ""; plural spadices , "") is a type of spike inflorescence having small flowers borne on a fleshy stem. Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known ''Anthurium'' spp. is a typical spadix with a large colorful spathe.〔(spadix ). CollinsDictionary.com. Collins English Dictionary - Complete & Unabridged 11th Edition. Retrieved October 18, 2012.〕 Monoecious aroids have unisexual male and female flowers on the same individual and the spadix is usually organized with female flowers towards the bottom and male flowers towards the top. Typically, the stigmas are no longer receptive when pollen is released which prevents self-fertilization. ==Gallery== Image:Arum flower.jpg|Elephant ear or ape flower (''Xanthosoma sagittifolium'') with a white spadix partially surrounded by a green-, rose-, and cream-colored spathe Image:Anthurium scherzerianum 2.jpg|''Anthurium scherzerianum'' inflorescence with spathe and spadix Image:Spathiphyllum floribundum1.jpg|Spadix of ''Spathiphyllum floribundum'' Image:Titan-arum1web.jpg| Titan arum (''Amorphophallus titanum'') spadix at the United States Botanic Garden Image:Flamingo Flower.JPG| Flamingo Lily (''Anthurium andraeanum'') at the United States Botanic Garden Image:Jack in the pupit.jpg| Jack in the Pulpit (''Arisaema triphyllum'') in the Allegheny National Forest, Pennsylvania) Image:Funchal - Zantedeschia aethiopica IMG 1904.JPG|Calla lily (''Zantedeschia aethiopica'') in Funchal, Madeira Image:Spadix of Spathiphyllum wallisii.JPG|Spadix of ''Spathiphyllum'' in Brazil.
