👉 Polyderis is a genus of flowering plants in the family Poaceae, commonly known as the sunflowers. They belong to the family of monocots and are native to North America. Each species has a unique shape, often resembling a sunflower but with a slightly flattened stem, leaves, and flowers. Polyderis is distinguished by its large, flat seeds, which can vary in size from small to medium-sized, depending on the cultivar.
