wow, you have sharp eyes! i went back and magnified and under that big leaf on the right i see some stalks - and what looks like serrated ridges, but barely!
what does 'winged on lateral margins' and 'wings undulate prominently' mean ? i went searching and i clearly see that i am missing a lot of vocabulary :(.
aroids.org is just dandy - i could give up plant-talk after that...the pics are grossly dim and small and they could've thought to put out some hand-drawn diagrams for illustration or smth...
