This is a common and widespread ephemeral herb with a lifespan of only about 4 months. The very small pale yellow flowers are followed by small seed heads (achenes) that are about 3mm across. The individual seeds are about 1mm across. The surface of the seeds are covered by small sharp hooks. They look for all the world like Velcro and I can only assume the serve the same function in seed dispersal by attaching the seeds to passing animals. (September 2008)
