Note this part As most recently defined Decker Walters et al 1993 free living gourds that occur in Texas are classified as C pepo ssp ovifera var texana Similar free living plants that occur in the U S beyond Texas Illinois Missouri Arkansas Oklahoma and Louisiana are placed in C pepo ssp ovifera var ozarkana There still seems to be disagreement on what to call and the relations between pepo texana and fraterna That 1993 ref is 20 years I m looking for newer stuff
