Classification

Following APG IV, the family includes the following families previously distinguished:

Key of subtribe Plectranthinae

according to Paton et al. (2019).

1 Corolla actinomorphic, or almost so, stamens spreading not declinate	Tetradenia
1 Corolla strongly zygomorphic, stamens declinate	2
2 Lateral lobes of the corolla deflexed towards the anterior lobe	Thorncroftia
2 Lateral lobes of the corolla ascending towards the median lobes of the posterior lip or horizontal and held between the anterior lobe and median lobes of the posterior lip	3
3 Posterior lip of corolla truncate, lateral lobes usually horizontal, short, held between the anterior lobe and median lobes of the posterior lip	Capitanopsis
3 Posterior lip of corolla not truncate, diverging from anterior lip of the corolla, with lateral lobes usually ascending and close to median lobes of posterior lip	4
4 Calyx basally circumscissile; tube distally dorsiventrally flattened	Aeollanthus
4 Calyx very rarely circumscissile; tube not dorsiventrally flattened	5
5 Calyx 3-lobed (1 upper, 2 lower), expanded and membranous in fruit	Alvesia
5 Calyx 5-lobed (1 upper, 4 lower, or actinomorphic), rarely expanded and membranous in fruit	6
6 Calyx with pedicel attached asymmetrically to the base of the calyx tube, opposite the posterior lip; corolla with upper (posterior) lip shorter than lower (anterior), rarely subequally lobed	Coleus
6 Calyx with pedicel attached symmetrically to the base of the calyx tube, not opposite the upper lip, corolla lobes more or less equal in length	7
7 Calyx throat truncate with lateral lobes of the calyx held midway between the uppermost and lowermost lobes; corolla tube usually sigmoid, parallel-sided at base, dilating towards throat	Equilabium
7 Calyx throat oblique with lateral lobes of the calyx held closer to the lowermost pair of lobes than the upper lobe; corolla tube straight or curved downwards, usually gibbous, saccate or shortly spurred at base	Plectranthus
