Calyx ± half as long as the corolla, divided completely at the back to 2-segments; each lateral segment 2-fid to sometimes almost entire, very variable, teeth ± as long as the tube or shorter. Corolla (12-) 15-20 mm long, usually conspicuously curved, glabrous to puberulous above, tubulose; tube often whitish or pale, hardly to slightly inflated below; limb shortly lobed, bluish, sometimes violaceous to brownish, irregularly toothed to subentire.
