26. Acinos Miller 1

Like Satureia but flowers always in verticillasters; calyx tubular, 13-veined, the tube usually curved, constricted near the middle and gibbous at the base, the limb 2-lipped with the lower teeth longer than the upper; style-branches unequal, the upper subulate, the lower longer and wider.

All species occur in dry, sunny habitats.

Intermediates between 2, 3, 4 and 5, presumably of hybrid origin, can be found in those areas where two or more of these species occur.

1 Leaves with obscure lateral veins and a translucent or whitish margin 1. corsicus

1 Leaves with conspicuous lateral veins and without a translucent or whitish margin

2 Corolla (10-)12-20 mm; perennial

3 Leaf-lamina mostly 1-2 times as long as wide, rounded or broadly cuneate at base, obtuse or acute 2. alpinus

3 Leaf-lamina mostly 2-3 times as long as wide, narrowly cuneate at base, acuminate or narrowly acute 3. suaveolens

2 Corolla 7-12 mm

4 Leaf-lamina not more than 1j times as long as wide, very prominently veined beneath, abruptly acuminate or mucronate 5. rotundifolius

4 Leaf-lamina usually at least l j times as long as wide, not prominently veined, obtuse or acute

5 Perennial with branched woody stock; corolla 10-12 mm, usually distinctly exceeding the subtending bract 2. alpinus

5 Annual or short-lived perennial; corolla 7—10(—12) mm, not exceeding the subtending bract 4. arvensis
