( Tunica armerioides (Ser.) Halâcsy ).

Perennial up to 30 cm, densely glandular-pubescent at base and apex, glabrous in the middle. Inflorescence fastigiate; pedicels 1-5 mm. Calyx 4-6-5 mm, teeth strongly 3-veined. Petals 6—8(—9) mm, oblong-spathulate, white, often purple-spotted at base; anthers usually purple. Seeds 1-8-2-1 x 1-0—1-3 mm. Aegean islands and S.E. Greece. Gr. The plants from the mainland of Greece and Evvoia are intermediate between 1 and 3 or 2 and 3. They usually have the stems glandular-pubescent throughout, and sometimes lax inflorescences with pedicels up to 9 mm. These latter plants have been confused with P. candica , from which they can be distinguished by the entire petals.
