Diagnosis.
Phryna hamzaoglui is related to P. ortegioides . It differs from P. ortegioides mainly because it has a calyx 4-5.5 mm long, teeth 2-2.5 mm long (not 3-4 mm long, teeth 1-2 mm long); petals completely white not purple veins, as long as calyx (not white with purple veins, 1.5-2 times calyx); capsule including calyx (not longer than calyx); seeds ventral and dorsal cells margine S-undulate (not V-Undulate) (Table 1 View Table 1 ).
Type.
TURKEY. B6 Malatya: Between Hekimhan and Hasançelebi town, 3 km from Hekimhan, 1100 m a.s.l., hillside, 10 October 2015, Koç 2353, Hamzaoğlu & Budak (holotype ANK; isotypes ANK, GAZI, Bozok Univ. Biology Dept. Herbarium).
Description.
Perennial herb. Stems woody caudex, dichotomously forked stems, 30-35 cm, base 1-1.2 mm diam., entirely mixed eglandular and with glandular hairs; internodes 13-20 mm, with glandular hairy. Leaves linear, 6-15 × 0.9-1.1 mm, with glandular hairs, 3-nerved, greenish, solid; acute at apex; sheath membranous, 0.2-0.3 mm long, having glandular hairy. Inflorescence mostly solitary, forming lax terminal racemes. Flowers sessile or subsessile. Bracts lanceolate, 3-4 × 0.8-1 mm; acute at apex. Bracteoles 2-3 pairs; acute at apex. Calyx narrowly campanulate, having densely glandular hairy, 4-5.5 × 1-1.2 mm, with 5 projecting ribs; teeth lanceolate, 2-2.5 mm long; acuminate at apex. Petals oblanceolate, 4-6 × 0.7-0.9 mm, as long as calyx, entirely white not purple veins; rounded at apex; base cuneate. Stamens 4; filaments 3-4 mm long. Styles 2, 3-4 mm long. Capsule oblong, 3.5-5 × 1-1.2 mm, 2-seeded, including calyx.
Seed micromorphology.
Seeds of Phryna hamzaoglui are comma-shaped with prominent radicle, 1-1.4 × 0.8-1 mm; blackish; lateral and dorsal surfaces tuberculate; cells subrectangle, regular; anticlinal cell walls certainly S-undulate; periclinal cell walls convex, wrinkled, upper smooth (Figure 2 View Figure 2 ).
Etymology.
The species is named in honour of the eminent Turkish botanist Prof. Dr. Ergin Hamzaoğlu (Gazi University, Ankara).
Distribution and habitat.
Phryna hamzaoglui is an endemic species known only from the type gathering in Central Anatolia (Hekimhan, Malatya) and is an Irano–Turanian element. Phryna hamzaoglui prefers hillsides at an altitude of 1100 m in Malatya province.
Phenology.
Flowering from August to September; fruiting from October.
Conservation status.
According to current data, Phryna hamzaoglui grows in an area of approximately 1000 km2 covering the Hekimhan districts of Malatya province. The species, which has a discontinuous distribution, has been reported in only one locality in Malatya. Due to overgrazing, the habitat of this species is under threat and destruction of the species is leading to the reduction in the number of plants. For this reason, it is proposed that the species should be classified as Endangered [EN (B1a)] according to the International Union for Conservation of Nature ( IUCN 2014).
