General Information

RENSEIGNEMENTS GÉNÉRAUX

Buffalobur is a fast-growing, spiny weed with toxic berries (CABI 2017). The berries may be dispersed by humans, mammals, water, and even wind, as the plants can become tumbleweeds. The berries are dehiscent, allowing the species to self-propel its seeds (CABI 2017).

Similar Species

ESPÈCES SEMBLABLES

Similar species are based on a study of seed morphology of various species, and those with similar dispersal units are identified. The study is limited by physical specimen and literature availability at the time of examination, and possibly impacted by the subjectivity of the authors based on their knowledge and experience. Providing similar species information for seed identification is to make users aware of similarities that could possibly result in misidentification.

Datura stramonium (jimsonweed)

Jimsonweed seeds have a similar shape, colour, and pitted surface as buffalobur.

Jimsonweed seeds are generally larger (average length: 3.6 mm; width 2.9 mm) than buffalobur, have shallow pits on the surface, and a triangular shaped hilum that is filled with white to pinkish tissue, unlike the round, open hilum of buffalobur.
