Clypeola glabra Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 173. 1842.
= Clypeola jonthlaspi subsp. microcarpa (Moris) Arcang., Comp. Fl. Ital.: 63. 1882.
Notes. – No material was cited by BOISSIER (1842b), but MEIKLE (1977: 144) gave the type as: “ Greece; in parte superiori montium Atticae Pentelicus, Parnes”, which is the same as that of the illegitimate and later homonym C. microcarpa Boiss.
Boissier in Flora Orientalis listed C. glabra in the synonymy of C. microcarpa Moris (non Boiss.). The failure to cite any collections in the original description of C. glabra does not allow accurate and final evaluation of the name status.
