Codonanthe is a genus of mainly epiphytic plants in the family Gesneriaceae, endemic to the Atlantic Forest of Brazil.

The flowers, produced in the upper leaf axils, on pedicels up to 1 cm (0.4 in) long, are either solitary or in groups of a few together, rarely in the form of a cyme.

[2] In one classification scheme for the family Gesneriaceae, Codonanthe is placed in the subfamily Gesnerioideae, tribe Gesnerieae, subtribe Columneinae.

[5] Within the subtribe, it forms a clade with Nematanthus, Codonanthopsis and Lesia:[6][2] Lesia Codonanthopsis Codanthe Nematanthus As of April 2021[update], Plants of the World Online accepted the following species:[1] Codonanthe species are endemic to Brazil, where they are found in the Atlantic Forest.

Their relatively small size and free-flowering habit make them easier to grow than other epiphytic members of the family Gesneriaceae, although their flowers are smaller and less colourful than those of some other genera.
