Diagnosis ( Figs. 2–3 ): — Astrantia haradjianii is closely related to A. maxima but differs several morphological traits. In A. haradjianii , the bracteoles only partially cover the flowers, with the flowers extending to at least two-thirds of the length of the bracteoles or longer. In contrast, the bracteoles of A. maxima more strongly enclose the flowers, which are typically no more than two-thirds of the length of the bracteoles. Additionally, the bracteoles of A. haradjianii are white and green, whereas those of A. maxima are pink to pinkish. The floral parts, including the pedicels, are white in A. haradjianii , while they are pinkish in A. maxima . Although the umbel size generally differs between the two species, with A. haradjianii producing smaller umbels, there is some overlap between the largest umbels of A. haradjianii and the smallest of A. maxima .

Description ( Fig. 2 ): — Perennial herb with rhizomes crowned by a fibrous collar. Stem erect, 40–70 cm, either branched from the base or simple; terete, ridged, hollow, glabrous. Basal leaves long-petiolate, petiole up to 20 cm; lamina 3–5 partite, segments ovate to elliptic-ovate, 3–7 × 1–4 cm, unequally serrate or crenate, with mucronate teeth. Cauline leaves sessile, sometimes amplexicaul, shapes similar to the basal leaves. Bracteoles white and green, 9–12, elliptic, oblong-elliptic or oblanceolate, 10–30 × 3–10 mm, slightly covering the flowers; nerved, with the margin setose-serrulate toward the apex. Inflorescence a simple umbel; lateral umbels (1)–3–5. Pedicels 3–12 mm, white, sometimes minutely hairy. Sepals white, persistent, linear-setaceous, 2–3 mm. Petals white, 1–2 mm. Fruit oblongcylindrical, 5–8.5 × 1.8–2.5 mm.

Flowering and Fruiting: —From June to September.

Distribution: — Türkiye ( Fig. 1 ).
