Notes: —This taxon was first described as one of the subspecies of M. varia present in Gran Canaria by Pérez de Paz (1978) . Molecular studies ( Meimberg et al. 2006 , Puppo et al. 2015 ) showed that it is different to M. varia present in Tenerife and deserves specific status. a. subsp. canariensis . Fig. 1–B , Fig. 3 . Subshrub up to 80 cm high; basal parts of branches glabrate, younger parts puberulent. Leaves blades 5–10 × 0.5–3 mm , green, basal blades lanceolate, flat, glabrate on both sides, abaxially puberulent on the midrib, upper blades linear, revolute, puberulent throughout. Cyme peduncles 2–5 mm long. Calyx green tinged with purple, puberulent, 2.5–3.5 mm long, calyx apices subulate, acute, ciliate. Corolla 3.5–5 mm long, exerted, lower lip projected upwards almost forming a 90º angle with the upper lip. Representative Specimens Examined: — SPAIN .

Habitat and Geographical Distribution: —This subspecies is restricted to the island of Gran Canaria where it grows in several localities in the NE side of the island between 400–1000 m . It is especially abundant in rocky, humid areas, in the border of the Laurisilva forest and humid gorges. Notes: —This subspecies grows in the humid northeast side of the island and is overall larger in size and less pubescent than subsp. meridialis from the drier zone. FIGURE 3 .

Subshrub up to 30 cm high; basal parts of branches densely puberulent, younger parts canescent. Leaves blades 3–6 × 0.5–0.9 mm , reddish or green tinged with red, all blades linear, revolute, densely puberulent to hirsute. Cymes sessile or shortly pedunculated; peduncles less than 2 mm long when present. Calyx reddish or lilac, tomentose, less than 3 mm long; calyx apices lanceolate, acute.

Geographical Distribution: —This subspecies is widely distributed on the southern side of Gran Canaria from 100 m up to the highest areas in the island. This subspecies grows in dry areas and is especially common colonizing abandoned fields. Notes: —This taxon was the other M. varia subspecies described by Pérez de Paz (1978) for Gran Canaria. Micromeria canariensis subsp. meridialis grows in the dry southeastern part of the island and is shorter and more pubescent than subsp. canariensis . The distinctiveness of subsp. meridialis was not supported by molecular studies since samples from both subspecies appear intermixed in phylogenetic analysis ( Puppo et al. 2015 ). This, together with the limited morphological separation of these taxa led us to treat them at subspecific rank.
