Basionym: — Arnebia purpurea Erik & Sümbül (1986: 151) .

Type: — TURKEY. Antalya: Gazipaşa, Sugözü köyü, Akçal tepesi, 1900–2000 m, 17 May 1983, Sümbül 3028 (holotype HUB! [no barcode number]; isotype E [E-00066270]). Fig. 8 .

Description: —Perennial grayish green plant, with stout scaly stock. Stem simple, 10–15 cm long, densely yellow setose. Basal leaves linear-lanceolate to oblong-lanceolate, 5–15 × 0.6–1.5 cm, apex acute, tapering into the petiole, with entire, flat, or sometimes slightly undulate margins; indumentum erect or patent, whitish only on the midrib. Cauline leaves, linear-lanceolate to oblong-lanceolate, 1.5–3 × 0.4–0.7 cm, acute or subacute, sessile, attenuate at base, with an evident midrib, veinless. Inflorescence a compact terminal head; 1.5–4 × 1.5–3 cm pedicels short, peduncle 1–2 cm long; bracts linear to lanceolate, 10–22 × 1–6 mm. Calyx 9–13 mm long in flower, up to 15 mm long in the fruiting state, broad at the base; lobes linear to lanceolate, acute, densely yellow setose, up to 2 mm long. Corolla dark red or purple, lobes 1–1.2 mm long, pubescent outside, glabrous inside; tube almost glabrous outside, slightly pilose at the middle, inside densely pubescent near the anthers, slightly constricted below the anthers. Annulus absent. Stamens inserted irregularly at different levels; three higher at the throat and two lower down in the tube. Anthers 1.2 mm long. Style 9–10 mm long, reaching up to above the middle of the corolla tube, shallowly bilobed, nearly up to the corolla lobes, sometimes exerted from the calyx lobes. Nutlets trigonal, slightly rugulose, keeled on the ventral side, beaked at the apex, shiny, annulate at the base. Other four dorsal keels obvious only on the ring. Ring chestnut brown, other parts whitish with brown striae. Beak acute, 1 mm long, curved to the ventral side.

Palynology: —Pollen grains elliptical shape and narrowly fusiform, stephanocolporate, equatorial axis (E) 24 μm, polar axis (P) 34 μm, in the higher number of apertures which is 6–7, ornamentation (sub) psilate ( Coppi et al. 2015).

Distribution: — Huynhia purpurea is a rare Turkish endemic species known to be distributed in a small area at Taurus Mts. in the southern part of Turkey ( Ekim 2009). Fig. 6 .

Ecology: —It occurs in rocky limestone slopes, ca. 1500–2000 m elevation.

Additional specimens examined: — TURKEY. Antalya: Alanya, Gökbel village ( Taurus Mts. ); 1665 m, 36° 42’ N, 32° 19’ E, sd., Cecchi et al.13.24 ( FIAF) ; Konya: Karahasan , between Sariveliler and Taþkent, 36º 44.91’ N, 32º 38.09’ E, 1800 m, sd., Cecchi et al. 13.38 ( FIAF) .
