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.
Hesperis matronalis (dame’s-rocket)
Hesperis matronalis seeds are a similar reddish-brown colour, and reticulate surface with a prominent rib formed from the radicle.
Hesperis matronalis seeds are generally smaller (average length: 2.6 mm, width: 1.4 mm), angular shaped, the ends appear pinched, the surface has negative reticulation with grooves and a porous appearance with smaller interspaces. The hilum tissue is not evident. The pod of dame’s-rocket is cylindrical with slight constrictions between the seeds.
