Özet
Cephalaria cameliensis Göktürk, Yıldırım & Özdemir, sp. nov. (Figs. 1–2, Table 1) Diagnosis: — Cephalaria cameliensis is closely allied to C. saldaensis, C. dirmilensis, and C. lycica, but can be readily distinguished from each by a combination of stable morphological characters. It differs from C. lycica in having an erect or ascending and completely glabrous stem (not procumbent, glabrous or minutely puberulent), lyrate basal leaves with only 1–2 segments (not 4–6), and linear to lanceolate simple cauline leaves (3–7 × 0.2–1.4 cm vs. oblanceolate–obovate, 2.5–4.5 × 0.4–0.7 cm); receptacular bracts oblanceolate (not oblong-spatulate); involucel is 3–5 mm (not 4–6 mm). From C. dirmilensis, it differs by the completely glabrous stem (not entirely minutely puberulent), basal lyrate leaves with 1–2 segments (not 2–4), oblanceolate receptacular bracts (not lanceolatecuneate), fewer flowers per capitulum (8–20 vs. 12–28), and a shorter involucel (3–5 mm vs. 6–8 mm). It is separated from C. saldaensis by its completely glabrous stem (not lower and middle parts minutely puberulent), smaller capitula (8–20-flowered vs. 15–25-flowered), and a shorter involucel (3–5 mm vs. 5–8 mm) bearing shorter teeth (up to 1 mm vs. 1.8–2.2 mm) (Table 1). TYPE:— TÜRKİYE.

Capitula ovoid, 8−20-flowered, 1−1.6 cm in diameter in flower, 0.4−1 cm in diameter in fruit. Involucral bracts orbicular or ovate-orbicular, 3−5 × 2−5 mm, pale purple to violet or straw color, pilose, margins ciliate, obtuse at apex; receptacular bracts oblanceolate, 6−10 × 2−4 mm, straw coloured at the base, purple-brown to violet in dorsal and at apex, pilose, margin ciliate, pilose at apex, acute at apex. Calyx cupuliform, 1 mm in diameter, with irregular teeth. Corolla pale blue, pinkish-purple or white, 8−11 mm long, densely adpressed pilose outside. Involucel 4-angled, 3−5 mm long in fruit, pilose, 4 long and 4 short teeth at apex; long teeth up to 1 mm long, short teeth up to 0.5 mm long. Distribution, habitat and ecology: — Cephalaria cameliensis is endemic to southwestern Anatolia, Denizli, and Muğla Provinces in Türkiye (Fig. 2). It is distributed in steppes ranging between 1350–1850 m a.s.l. It is associated with other many endemic plants as Echinops emiliae O.Schwarz ex P.H.Davis (1956: 69), Alkanna pamphylica Hub.- Mor. & Reese (1943: 50), Muscarimia muscari (L.) Losinsk. (1935: 411), Ajuga bombycina Boiss. (1879: 803), Salvia potentillifolia Boiss. & Heldr. ex Benth. (1848: 270), Verbascum trapifolium var. flabellifolium (Hub.-Mor.) Karavel. & Aytaç (2008: 17), Asyneuma michauxioides (Boiss.) Damboldt (1976: 49), Anthemis rosea Sm. subsp. subsp. carnea (Boiss.) Grierson (1974: 217), Arenaria tmolea Boiss. (1843: 50), Hypericum albiflorum (Hub.-Mor.) N.Robson (2010: 45), Verbascum bellum Hub.-Mor. (1939; 170), Ptilostemon afer subsp. eburneus Greuter (1973: 97), Centaurea drabifolia subsp. austro-occidentalis Wagenitz (1963: 160) and other non-endemic plants as Aethionema cordatum (Desf.)

(1932: 40), Satureja cuneifolia Ten. (1812: 33). Phenology:—Flowering from June to August. Fruiting from August to September. Proposed conservation status: — Cephalaria cameliensis is currently known from four adjacent localities with small subpopulations in Denizli (Çameli district) and Muğla (Fethiye district). The extent of occurrence (EOO) of the new species is estimated at 16 km ², and the area of occupancy (AOO) at 120 km ². Based on these values and its restricted distribution, the species is proposed to be assigned to the IUCN threat category “Endangered EN [B1 + B2a,b(i,ii) + C2a(i)]” (IUCN 2024). The global population size is estimated to comprise 200–350 mature individuals per subpopulation. Furthermore, its population size, extent of occurrence, and area of occupancy are likely to decline in the near future due to intense grazing pressure, localized livestock grazing observed in some populations, and other anthropogenic impacts. Therefore, is necessary to evaluate specific actions to be undertaken for in situ and ex situ conservation, as already done for other taxa in similar ecologically condition (Wagensommer et al. 2020, Perrino et al. 2022) Etymology: —The specific epithet is derived from the type locality.
