This looks like a passion flower to me but it has not been identified by the editors of the facsimilar edition of Frei Cristovao de Lisboa’s drawings (Maranhao, Brazil, 1625-1631).

Can someone identify it?  

Passion flower (Passiflora) sketch drawing by Frei Cristovao de Lisboa while he was a missionaire in Maranhao, Brazil (1625-1631) .

From “Historia dos animais e árvores de Maranhao” probably written between 1625 and 1631 by  Frey Cristovao de Lisboa:  Snowy Egret  (Egretta thula) and Little Blue Heron  (Egretta caerulea).
