Holocarpha obconica, also known as the San Joaquin tarweed, is a plant found in North America. It belongs to the sunflower family.

About the San Joaquin Tarweed
The name "obconica" describes the plant's shape. It means "obconical," which is like a cone but wider at the top than at the bottom. The seeds of H. obconica have this special shape.
What Does it Look Like?
This plant is a type of herb that contains resin, a sticky substance. It can grow up to 120 centimeters (about 4 feet) tall. The San Joaquin tarweed produces many flower heads. Each flower head has 4 to 9 yellow ray flowers. These are the petal-like parts you see on a sunflower. Inside, there are 11 to 21 small yellow disc flowers. These disc flowers have yellow or brown anthers, which are parts that hold pollen.
