Cayaponia
Bejucos herbáceos, monoicos o dioicos, glabros o pubescentes, con zarcillos axilares o laterales a las hojas; látex acuoso, usualmente abundante. Hojas alternas, pecioladas; láminas simples, enteras, lobadas, palmatilobadas o palmatífidas; estípulas ausentes. Flores unisexuales, actinomorfas, solitarias o en racimos, panículas o fascículos axilares. Cáliz campanulado, con 5 lóbulos diminutos; corolas tubulares, con lóbulos reflexos o expandidos; flores estaminadas con un pistilodio y 3 estambres exertos, los filamentos adnatos a la corola, las anteras sigmoides, concrescentes; flores pistiladas con 3 estaminodios; ovario ínfero, 3-carpelado, trilobado, el estilo simple, con 3 ramas estigmáticas. Fruto una pequeña baya; semillas 2-3, comprimidas. Género predominantemente neotropical con alrededor de 60 especies.

Cayaponia is the largest genus in the gourd family Cucurbitaceae, with about 60 species. The plants are referred to as melonleaf. They are common from the southern United States to South America. Some species are also found in western Africa, Madagascar, and Fernando de Noronha, which is about 354km off the coast of Brazil.[2][3] It is native the southern United States to central South America and the Caribbean islands. Most species are found in rainforests and have white or yellow-green flowers. The original Cayaponia were pollinated by bats, but at least two shifts to bee pollination have occurred among some of its species. This is apparently the first clade to shift from bat to bee pollination vice bee to bat pollination.[4] A 2011 study based on genetics placed the genus Selysia under this genus.[5]
Brazilian botanist António Luiz Patricio da Silva Manso named this genus after the indigenous Cayapo people of Brazil.[6]
