Ok Camillo Alexis...I got you covered!
first pic..from top left going clockwise...E uniflora, E. involucrata, E. brasiliensis, E. victoriana, and E. involucrata.
bottom three pics look like involucrata...the leaves can be rounded or more lance shaped, it just depends...looks like you have two different shaped leaves for whatever reason...I've got seeds with rounder leaves too...they can be variable.
