Discussion:

Momordica charantia has at least three forms that are cultivated for their edible fruits. These are known as "bitter melon" and "bitter gourd" and may attain up to 60 cm long. In Puerto Rico the wild form, not a cultivated one. is found, although there exists one collection (Sintenis 919), made in 1885, with fruits ca. 15 cm long, apparently from a cultivated plant.
