Family Fabaceae (habit, leaves, fruit)

habit: herb → vine → tree

leaves: stipules, compound leaves, pulvini/pulvinus, entire margins, tendrils

fruit: legume, ovary superior

pulvini/pulvinus (plural/singular)

responsible for moving leaflet, pull water out and in (to move leaf)

-if need to reach more sun → move

legume

-single carpel

-usually 2 sides split open one carpel (2 lines of dehiscence)

-essentially a “follicle”
