Diagnosis.

Tulipa cinnabarina subsp. toprakii differs from similar Tulipa cinnabarina subsp. cinnabarina by its smaller anthers, narrower outer perianth segments, outer segments with mostly blackish base or buff colored on all of outer surfaces, and smaller capsul sizes, weakly stoloniferous structure, and 2-4 leaves.

Type.

Description.

Plant 18.0-39.0 cm. Stem glabrous, stem width 1-2.5 mm, subterranean stem length 7.0-14.0 cm, aerial stem length 7.0-20.0 cm. Weakly stoloniferous or not. Bulb ovoid, 1.5-2.2 × 1.8-2.4 cm. Bulb neck 2.5-7.0 cm. Tunics coriaceous, dark brown, innermost tunics with a ring of short hairs around basal plate and, adpressed, pilose, bristly with longer hairs at neck, middle part glabrous. Leaves 2-4, falcate to erect-patent, lanceolate, canaliculate, glaucous, alternate or ± crowded, leaf margin membranous, glabrous or ciliate, and entire; lowest leaf 13.0-21.0 × 0.7-1.3 cm, subacute; second lowest leaf 10.0-17.0 × 0.4-0.9 cm, acute to subacute. Flower solitary, infundibular, bright dark red to orange red inside and paler red to orange red outside with mostly blackish base or buff colored on all of outer surfaces, mostly no blotch inside, rarely with a very short yellow blotch; outer tepals elliptic, narrowed at base, suacute to acute, glabrous and pubescent only at tip, 27-41 × 6-8 mm; inner tepals elliptic-obovate, narrowed at base, obtuse or obtuse-apiculate, pubescent at tip and distinctly pubescent at base, 29-44 × 10-16 mm. If it is present, outer and inner blotchs 6-10 mm in length; blotch 1/5-1/6 length of segments. Filaments blurred shades of red, orange, yellow or brown, lanceolate and pubescent at base; outer filaments 7.0-11.5 mm, inner ones 8.0-12.5 mm. Anthers 2.5-6.0 × 1.0-1.5 mm when dry, oblong, bluish-black when fresh, apiculate or not. Pollen yellow or orange. Ovary oblong, fusiform or subfusiform, pale green, yellowish-green or reddish-green when fresh, glabrous, 9.0-11.0 × 3.0-5.0 mm. Style short or obscure, 0.5-1.5 × 1.0-2 mm. Stigma pubescent, whitish-yellow or yellow when fresh, 0.5-0.6 × 1.0-1.5 mm. Capsule 1.5-2.0 × 1.0-1.3 cm, elliptic-obovoid to obovoid, glabrous; neck 0.5-1.0 mm, rib 14.0-16.0 mm, beak 2.0-4.0, apicula 0.5-1.0 mm; tepal scar 0.5-1.0 mm. Seeds numerous, flattened with rugose surface, triangular with two rounded angles to orbicular, light brown, 4.0-5.0 × 3.0-4.0 mm, winged.

Etymology.

This new subspecies is named in honour of Ayhan Toprak, who first collected the new species. The Turkish name of this species is given as "Milas Lâlesi”, according to the guidelines of Menemen et al. (2013).

Suggested conservational status.

The occupancy area (AOO) of Tulipa cinnabarina subsp. toprakii was calculated as 0.012 km2 in which about 600-750 individuals were estimated to occur. The individual of new subspecies found in Olea europaea L. orchard. On the other hand, overgrazing by sheep and goat herds and development of new road for mines were observed to be producing negative effects on the surroundings of the known populations, which are seriously threatened habitats of it. These strong anthropic pressures on this new subspecies are responsible for rapid habitat destruction, and they could cause a dramatic decrease of the number of reproductive individuals in the near future. Therefore, in accordance with the criteria of the IUCN (2012), Tulipa cinnabarina subsp. toprakii is here assessed as "Critically Endangered" (CR) B2ab(i,ii,iii), on account of its restricted distribution in Turkey with an inferred severe decline of the extent of occurrence, the occupancy area and quality of the habitat.

Distribution and ecology.

Tulipa cinnabarina subsp. toprakii is endemic to west Anatolia (Fig. 3 ). It is an element belonging to the Mediterranean floristic region. It grows on calcareous soils at opening slopes and clearings in Olea europaea orchard. The associated species include: Allium neopolitanum Cyr., Anthemis cretica L. subsp. leucanthemodies (Boiss) Griersan., Anthemis macrotis (Rech.f) Oberpr & Voght, Cistus creticus L., Fritillaria minuta Boiss., Melilotus indica (L.) All., Olea europaea , Ophrys iricolor Desf., Pinus brutia Ten. Ranunculus muricatus L., Ranunculus repens L.
