Sagina subulata (Heath Pearlwort; syn. Sagina pilifera auct. non (DC.) Fenzl) is a species of Sagina, native to Europe, from Iceland south to Spain, and east to southern Sweden and Romania. It occurs on dry sandy or gravelly soils.[1][2][3]

Heath Pearlwort is a low-growing prostrate perennial plant forming a thick, dense mat with stems less than 10 cm long, and slender subulate (awl-shaped) leaves up to 1 cm long. The flowers are 4–5 mm diameter, with five white petals the same length as the green sepals; they are produced singly on erect stems 2–4 cm long. The seeds are smooth, brown, triangular shaped, 0.4–0.5 mm, produced in a capsule 2.5–3 mm long.[3][4][5]
