**Description:** A woodland wildflower with star-shaped yellow flowers that grow in groups (whorls) of four around the stem.
**Size:** 1 to 3 feet tall.
**Behavior:** Unusual because the flowers do not produce nectar; instead, they offer a specialized floral oil to attract specific oil-collecting bees.
**Identification:** Highly symmetrical plant with neat whorls of four leaves and four matching yellow flowers.
**Habitat:** Dappled sunlight of deciduous forest floors and shaded trail edges.
