Calamintha clinopodium
from the link ☼
---Description---The shortly - stalked, egg shaped leaves, 1 to 2 inches long, are placedopposite to one another on the four-angled stem, the pairs being some distance apart. They are only slightly toothed at their edges and like the stem are downy with soft hairs.
The flowers, with tubular, lipped corollas of a pinkish colour, are arranged on the stem in several crowded, bristly rings or whorls, at the points from which the leaf-stalks spring, and are in bloom from July to September.
The whole herb is aromatic and fragrant, with a faint Thyme-like odour, and like Calamint has been used to make an infusion for similar complaints.
