The Bur Cucumber (Sicyos angulatus) is a vine that grows mostly in moist soils of alluvial woods, river banks, and roadsides. It blooms from August until frost. There are 8-20 white to cream flowers in compact clusters. The laterally-compressed berry is covered with bristles and has only one seed.
Many Bur Cucumber vines, with their large conspicuous leaves, can be seen growing along the Riverwalk Trail in Danville.
The generic name, Sicyos, is derived from the Greek name for cucumber; the specific name, angulatus, relates to the pointed lobes of the leaves.
This member of the gourd family, when handled, is found to be clammy-hairy throughout.
