Term:
Cylindrical fruit
Cylindrical fruit
Definition:
A fruit that is much longer than it is broad.
A fruit that is much longer than it is broad.
Notes:
In Lecythidaceae, fruits at least 1.5 times longer than broad and more-or-less the same diameter throughout are considered cylindric. Only a few species possess fruit that are truly cylindrical (e.g., Allantoma lineata) because most species that are longer than broad in the Lecythidaceae taper at least slightly at the ends; nevertheless, these species, e.g., Couratari guianensis, are considered cylindric in the broad sense. Although it is difficult to more specifically classify their forms, species with cylindric fruits do vary among themselves by subtile differences in their forms.
