Shrub, or plant
'A shrub' or 'plant,' as in Genesis 21:15, denotes perception, but so little that it is hardly anything, in same way as 'trees,' but to a lesser degree. So 'to be cast under one of the shrubs,' signifies being destroyed regarding truth and good, to the point of desperation.

1 Kings 2:32
32
And the Lord will send back his blood on his head, because of the attack he made on two men more upright and better than himself, putting them to the sword without my father's knowledge; even Abner, the son of Ner, captain of the army of Israel, and Amasa, the son of Jether, captain of the army of Judah.
