Flowers and Fruits

On the early eve of September 10, 2019, when temperatures blazed a warm 90°F, I took my bike up the Olentangy Bike Trail, north of Lane Avenue near Tuttle Park to identify some flowers and fruits. [Template: I=Scientific name, II=plant description, III=location, IV=inflorescence type, V=comments]
