Today's word is complex. As in "the Stylosanthes biflora complex". In the past this pencilflower has been split into many species because of its extreme variability. But the variations overlap so much that those species are now united as the S. biflora complex. The sort of complex situation that many plants use to defy our need to sort them out! Other complex suspects include blackberries, apples, hawthorns, and panicgrass. This complex is encountered in AL, AR, AZ, DE, FL, GA, IL, IN, KS, KY, LA, ND, MO, MS, NC, NJ, NY, OH, OK, PA, SC, TN, TX, VA, WI, and WV. Oconee Co GA, 7/7/18. Bean family, Fabaceae.
