Astrantia minor
''Astrantia minor'' is a species of herbaceous plant belonging to the family of Apiaceae.
== Description ==
A. minor is a flowering plant that often reaches 15–30 cm in height, with simple ''stems'', rarely branched in the upper half, the basal ''leaves'' are of two types, often on the same plant: one with narrow segments that are all pinnatisect, the other with broad segments, the central being pinnatisect and the lateral being deeply pinnatipartite; ''petioles'' 4–12 cm; the ''leaf blade'' with (5) 7 (8) segments of 1-3 (4.5) x 0.5 -1.3 cm, pale green, toothed in upper half or two thirds, the stem at the base of the ''inflorescence'', from 2 to 3.2 x 0.2-0.5 cm reduced to 3-5 segments. ''Inflorescence'' with 1-3 ''peduncles'' unequal, the central, sometimes branched, and longer than the sides that have unique umbels; ''Umbels'' surrounded by (10) 12-14 ''bracts'', 4-10 x 1–3 mm, membranous, entire, the apex green with three ribs. The ''flowers'' are 30-40 per umbel, of the same length or slightly shorter than the bracts, generally hermaphroditic in the centre and male peripherally. ''Calices'' have teeth about 1 mm in size, ovate-oblong, subobtuse and slightly bearded (1.5-2 times longer than wide). ''Petals'' are similar in size to the ''sepals'' and white or cream. ''Stamens'' exserted. ''Fruit'' ovoid (1.5) 2–5 mm with scales in the form of a vesicle, subobtuse.
It differs from its congener Astrantia major, by its smaller size, and basal leaves of seven segments (instead of five) with calyx teeth that are obtuse and slightly mucronate.
