And you thought you had knobby knees?
“Especially in areas where water levels fluctuate, they tend to form knobby protuberances, called knees. These outgrowths from the lateral roots sometimes reach 12 feet in height, but their precise function—whether support, food storage, or aeration—is unknown.”
