- Sepals 3 or more than 3 times the length of petals ....................................................................................................... 2

2. Racemes 3–4 cm long, short and compact (Peloponnese, Greece) ................................................ G. peloponnesiacum

- Racemes 6–20 cm long, lax or dense .......................................................................................................................... 3

3. Tuber 4–15 cm in diameter; flowering stems 4–14, 4– 7 mm in diameter, appearing before the leaves; raceme dense, 12–25(–40)-flowered; leaflets thick, glaucous, often emarginate (southern Albania) ..................................... G. maloi
