Both Daucus

Daucus carota vs Daucus pusillus

These two are not on this page because a keyword tool suggested them. They are here because our own identification model genuinely mistook one for the other, on real photographs, 7 times. We publish the rate, and then we tell you what actually separates them.

What actually separates themon the record

Family Both Apiaceae. The family does not separate them.
Genus Both Daucus. Congeners, which is why this is hard.
Flowering Peaks in July versus April. If the plant is in flower, timing helps. (n = 15,123 and 315.)

What we do not have yet: the diagnostic morphological character that a botanist would key on, from a source we can cite. We are not going to invent one. Until we have it, this page tells you the two are genuinely confusable, how often, and what the taxonomy and the flowering data do and do not settle.
