Population structure of Goodyera crassifolia and its closely related taxa, inferred with STRUCTURE 2.3.4. Using K = 2 and K = 3 generated the largest and second-largest delta K, indicating that they were the most and second most optimal, respectively. Species and populations are separated by broad and narrow vertical black lines, respectively.
