Perennial of the Saxifragaceae family, Gymnopera section. This subspecies, endemic to the central and western Pyrenees, is distinguished from the typical form by a noticeably more compact and clustered habit, as well as leaves with fewer and less pronounced crenulations, as indicated by its epithet. It occupies shaded rocks, moist crevices, and cool high-altitude undergrowth, generally between 800 and 2000 meters.
The rosettes, tight and dense, are formed of orbicular to reniform leaves, medium green to gray-green, covered on both sides with a stiff and abundant hairiness that gives them a very noticeable velvety texture. This feature, much more pronounced than in the typical subspecies, is immediately striking and gives the plant an almost woolly appearance upon close observation.
The floral stems, thin and glandular, modestly rise to 10–20 cm and bear small light panicles of cream-white to pinkish-white flowers. In its natural habitat, its flowering extends from June to July. In cultivation, it generally occurs in May-June depending on exposure.
It is cultivated in cool, humus-rich, and well-drained soil, in shade or partial shade, sheltered from drought and direct sunlight. Its contained size and the remarkable texture of its foliage make it an interesting candidate for shaded rock gardens or alpine troughs.
