Counting Fully-developed Trifoliates

Count the number of fully-developed Trifoliates. Trifoliates are compound leaves with three leaflets (see image below). When the trifoliate first emerges from the bud, the leaflets are folded in half with the leaf edges (margins) touching. The trifolates are considered fully developed when the leaflets unfold to the point where the leaf margins are no longer touching (see photo below).
