Hackelia virginiana, commonly known as beggar's lice,[2][3] sticktight or stickseed,[3] is a biennial plant native to Eastern North America. It has simple, rough leaves and ribbed green stems.

The flowers are small and white, bourne in mid-late summer.[4] The seeds are burs, and are very sticky. The seeding part of the plant -- the upper stem -- dies earlier than mos other plants, and becomes very brittle. Often the entire seed stem, or even the entire plant will come out of the ground if the seeds catch on clothing or fur, so it is generally considered to be a pest plant. These are some of the smaller "tick seeds" in its range, and the seeds can burrow deep within certain clothing, such as socks.

During the plant's first year of growth it has only a basal rosette of foliage, with the flowering stalk ascending the second year. The leaves are dark green and irregularly shaped.
