Chaenorhinum minus, also known as small toadflax in Europe and dwarf snapdragon in the US and Canada, is a very diminutive member of the plant family Plantaginaceae.

[3] Chaenorhinum minus differs from many toadflaxes in having alternate leaves growing singly.

Its leaves and sepals are covered with glandular hairs.

Once a common weed in farmers' fields, it has suffered from agricultural intensification and is now mainly seen in gardens and around railways, as well as roadsides and industrial sites.

[2][3] Its UK distribution shows it favours chalky soil.
