In Italy there are three species of Drimia:

Drimia Jacq. ex Willd. [1787, Sp. Pl., 2 (1) : 165] (Hyacinthaceae) SPETA (1980), STEARN (1978b) (Epimenidion, Urginea, Scilla, Squilla, Stellaris) T : D. elata Jacq. ex Willd.

Drimia fugax (Moris) Stearn [1978b, Ann. Mus. Goulandris, 4 : 204] 2n = 20 Co 6

Drimia maritima (L.) Stearn [1978b, Ann. Mus. Goulandris, 4 : 204] 2n = 20, 30, 40 Co, Ga 6

Drimia undulata Stearn [1978b, Ann. Mus. Goulandris, 4 : 208] 2n = 20, 60 Co 6

I grow D. maritima and undulata in an unheated greenhouse  but they do not flower regularly.

Drimia acarophylla (Hyacinthaceae), a new species from Eastern Cape, South Africa. South African Journal of Botany    1 October 2003, vol. 69, no. 3,   pp. 396-400(5). Brink E.; Dold A.P.

Abstract:
Drimia acarophylla, a new, inconspicuous, dwarf species from the Albany Centre of Endemism in Eastern Cape, South Africa, is restricted to the Great Fish River floodplain where it is found in small colonies on bare patches of blue-grey pencil shale, where it is further camouflaged by the leaves resembling engorged female blue ticks. It shows affinity to D. depressa (Bak.) Jessop, which is known from the Eastern Cape to KwaZulu-Natal, Lesotho, Swaziland and Northern Province, in their shared capitate inflorescence and spreading tepals but is distinguished by its terete, succulent, clavate leaves with a cuticle of densely packed, multifaceted, erect
wax platelets. Upon fading the inner tepals close first and their papillate apices fuse with the stigmatic papillae, the stamens wilt and the anthers connive with the style just below the stigma.
