Key to the annual Minuartia species occurring in Turkey:

1. Inflorescence densely arranged; flowers sessil or subsessil (pedicels less than 1 mm); sepal veins with clusters of calcium oxalate crystals appearing as disc-like swellings............................................................................................................................................ 2

− Inflorescence usually lax or ± dense; flowers pedicellate (pedicels more than 1 mm); sepals without clusters of calcium oxalate crystals................................................................................................................................................................................................ 6

2. Inflorescence globose; bracts enclosing the sepals, basal membranaceous margin 0.6–1 mm; sepals outcurved; fruit 1–seeded ...... ............................................................................................................................................................................................ M. hamata

− Inflorescence not globose; bracts not enclosing the sepals, basal membranaceous margin 0.1–0.4 mm; sepals erect or incurved; fruit 2–12-seeded ................................................................................................................................................................................ 3

3. Inflorescence in terminal clusters only; leaves linear-setaceous; bracts basal membranaceous 0.2–0.4 mm; sepals slightly incurved; staminal glands vase shaped; seeds ventral and dorsal surface tuberculate .................................................................. M. sclerantha

− Inflorescence in both lateral and terminal clusters; leaves linear-lanceolate; bracts basal membranaceous 0.1–0.2 mm; sepals erect; staminal glands finger-like; seeds ventral surface tuberculate and dorsal surface papillate .............................................................. 4

4. Inflorescence glandular-pubescent; petals 1/2–3/4 as long as sepals; staminal glands 5................................................ M. decipiens

− Inflorescence glabrous or pubescent, not glandular; petals absent or up to 1/4 as long as sepals; staminal glands 10 ..................... 5
