A most peculiar creature..possibly not a Passiflora at all or highly stylised.
Jacopo Ligozzi 1609
'Granadilla, seu Flos passionis Aurantii foliis
coniugatis, elegantibus floribus ad alas racematim dispositis, plerunque senis'
'Granadilla, or Passion Flower, with orange tree-like opposite leaves, with elegant flowers grouped into racemes often of six flowers, at the leaf axils.'
