Definition: Navigobius is a genus of small, arboreal plants in the family Fabaceae that are commonly found growing on trees and shrubs. These plants have a single leaf with a long petiole and a narrow blade at the base, which they use to reach the leaves up towards the branches. They are typically sessile or semi-sessile, meaning they do not grow as a continuous canopy over their host plant but rather move along the surface of the ground to access the leaves
