They are herbaceous plants, or shrubs. It has an erect, branched stem, without scaly rhizomes. The leaves are arranged in the opposite way. The inflorescences are axillary, in cymes or solitary flowers. The corolla is red, orange or yellow, in the form of a long tube, which is broader in the centre. With the base of the extremities and narrow throat. The fruit (or seed capsule) is a dry, ovoid or ellipsoidal bivalve capsule. Taxonomy 
It was previously included in the genus Kohleria, but with a different chromosomal number 2n=11, the ring-shaped nectary and without rhizomes. The molecular results support the separation of this genus. The genus name of Moussonia is in honour of Albert Mousson (1805–1890), a physicist and a malacologist from Switzerland.. It was first described and published in Flora Vol.31 on page 248 in 1848. Species
