Etymology

The specific epithet major, meaning "larger", distinguishes this species from its smaller relative Astrantia minor.[1]

Astrantia major reaches on average 60 centimetres (24 in) of height. The stem is erect and glabrous, with little branches and few leaves. The basal leaves have a long petiole 10–20 centimetres (3.9–7.9 in), 3 to 7 lobes and toothed segments. Size: 8–15 centimetres (3.1–5.9 in). The cauline leaves are generally two, sessile, amplexicaul and lanceolate-shaped with a trilobed apex. The inflorescence is umbrella-shaped, with 2–3 centimetres (0.79–1.18 in) of diameter. The floral bracts are numerous (10 - 20), 10–18 millimetres (0.39–0.71 in) long, reddish (sometimes white) with acuminate apex. The small flowers are greenish-white with reddish shades. The central ones are hermaphrodite, while the external ones are male. The petals are five, white (or slightly reddened), while the stamens are five and much longer. Size of the flowers: about 1 mm. The flowering period extends from June through September.
