Distribution of the species
It has been observed in both low altitudes (150-550 m asl.), and in the zone of subalpine grasslands, at altitudes c. 1,600-1,700 m asl. It is also expected to be found in other places, always in limestone.
Description of the species (biological and ecological features)
This is a fairly common species in northeastern Greece, whose population is estimated to be quite large. Multi-branched, small shrub, with stems up to 25 cm tall, covered with soft hairs. The leaves are narrowly ovate to oblong-elliptical, 3-4 times longer than their width, with an acute apex and usually folded along their central vein, up to 2 cm long. Its leaves are characterized by visible hairs, as well as invisible glandular scales. The name pilosa is due to its hairiness, which comes from the Latin word pilosus, meaning hairy. Inflorescence relatively long, consists of several verticillasters, each with numerous flowers (6-14 or marginally up to 24 flowers at each verticillaster). The color of the flowers is light pink to violet and the bicolor corolla is 8-10 mm long. It is a plant relatively rich in essential oils, with a slight lavender aroma. In some areas, it is collected and can be used as a winter drink. It grows on stony, barren slopes, as well as on forest edge and asphalt road sides. It is also found near river banks and openings in plane tree stands. Rarely grows in rocky crevices, always in limestone. Its altitudinal range is large, as we can see it from low altitudes (about 50 m) up to over 1,000 m or up to 1,700 m. We will see it flowering during the months July and September, whereas it flowers until November at low altitudes.
Due to its relatively wide distribution on Mount Paggaio, no particular threats and pressures were observed or reported, which could lead to a significant reduction in its population.
