ID Keys

SEED ID KEYS

The first time user of the digital key, please refer to the User Guide

ID Key was developed  for common plant families using LUCID builder 3.3.  It contains feature descriptors describing plant families when a family identification is needed for an unknown seed or fruit.

Unlike the traditional dichotomous key, this character-driven tool allows the user to choose which descriptive features best fit the seed or fruit in hand. This aids in determining the family of the unknown seed or fruit.

Each family has a number of identification features programmed into the ID key. If a seed feature is selected that does NOT occur in a particular family, the program will eliminate it from the possibilities. The user will see the number of potential families decrease and the eliminated families increase as they work through the ID key.
