Thymus caespitius Brot.

Accepted name: Thymus caespititius

Cushion-forming, low shrub becoming very woody at the base. Young stems prostrate, rooting eventually at the nodes, not markedly angled, covered all round with tiny hairs. Leaves thickish, with inconspicuous veins, green to yellow-green, 6-10 mm long, 1.5 mm wide, narrowly spoon-shaped, widening slightly to a sheathing base, glabrous except for conspicuous, sparse 1 mm cilia on the margins. Bracts like the leaves but smaller. Flowering heads few-flowered, with flowers single in the axils. Calyx green; lower lip with narrowly triangular ciliate teeth, upper lip concave, round, with 3 tiny teeth. Corolla pale lilac without deeper coloured markings, lower lip 7 mm wide, with 3 equal lobes, the middle one notched; upper lip notched, set at right angles to the lower lip so that the flower looks 3-lobed from above. [T. micans Lowe, T. azoricus Lodd.]
