Lamiaceae

1. Corolla actinomorphic, or almost so, stamens spreading not declinate Tetradenia
2. Corolla strongly zygomorphic, stamens declinate. 2
   1. 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

1. 1. 1. Posterior lip of corolla truncate, lateral lobes usually horizontal, short, held between

the anterior lobe and median lobes of the posterior lip..........Capitanopsis

1. 1. 1. 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

1. 1. 1. 1. Calyx basally circumscissile; tube distally dorsiventrally flattened....Aeollanthus
         2. Calyx very rarely circumscissile; tube not dorsiventrally flattened.....5
            1. Calyx 3-lobed (1 upper, 2 lower), expanded and membranous in fruit......Alvesia
            2. Calyx 5-lobed (1 upper, 4 lower, or actinomorphic), rarely expanded and membranous

in fruit.....6

1. 1. 1. 1. 1. 1. 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 (Fig. 3)........... Coleus

1. 1. 1. 1. 1. 1. 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 (Fig. 3)........7

1. 1. 1. 1. 1. 1. 1. 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 (Fig. 3)..... Equilabium

1. 1. 1. 1. 1. 1. 1. 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 (Fig. 3).......Plectranthus
