Diagnosis.

The new subspecies is similar to Grammosciadium pterocarpum subsp. pterocarpum , but mainly differs from it by the fruits with the narrower wings of lateral ribs (0.5-0.8 mm, not 1-3.1 mm).

Type.

Turkey. B3 Eskişehir: around of Yarimca village , clearings of oak woodland, 1250 m, 20.06.2014, B.Bani 6983, E.D. Güner (holotype GAZI!) .

Perennial, erect, branched (at third node or above) herbs. Rootstock with remaining of elder leaf bases. Stem 35-50 cm long and 0.15-0.40 mm broad (just below the first node), angular, prominently or slightly striate, always smooth, white, green or purplish at base. Basal leaves petiolate; petioles 2.5-8 cm long, broadly sheathed towards base, always smooth, prominently ribbed, canaliculate or flat, angular or triangular. Lamina 5-pinnatisect, 5.5-12 cm long, glabrous, linear-elliptic in outline; primary segments 0.5-1.3 cm long, distance between primary segments 0.4-1.5 cm long; ultimate segments 2-4 mm long, mucronate at apex. Lower leaf sheaths mostly connate at base, with stipular segments at margins; stipular segments sessile or shortly petiolate. Upper leaves similar but decreasing in size upwards. Bracts 3-6, trisect or up to 1-3-pinnatisect, 0.6-1.6 cm long; rarely narrowly sheathed; segments 0.3-0.7 cm, always smooth, mucronate at apex. Rays 5-9, unequal, 2.5-5.5 cm. Bracteoles 5-7, trisect to 1-pinnatisect, 0.35-0.65 cm long, always smooth. Flowers male only or hermaphrodite, 8-18, slightly radiate. Pedicels of male flowers 0.15-0.6 cm long. Sepals 0.14-0.5 mm long, smooth, patent or erect. Petals cordate, with long central oil duct, largest petal 2.8-3.5 mm long. Stamens 5; longest filament 1.3-2 mm long. Fruiting pedicels 3.5-5 mm long. Fruits, 9-16 per umbellule, oblong or narrowly lanceolate, 0.7-1.1 × 0.1 cm; each mericarp has 5 primary ribs and four secondary ribs alternating with the primary ribs; lateral ribs winged; wings 0.5-0.8 mm. Stylopodium minute up to 0.5 mm long. Styles divergent, 0.8-1 mm, uninerved on outer side. Flowering May-June; fruiting June-July.

Etymology.

We dedicate this new subspecies in memory of our dear colleague Dr. Bilgehan Bilgili who passed away in 2015.
