Abstract
Ornithogalum christiniae sp. nov., collected from the offshore islet of Agria Gramvousa (northwestern Crete, Greece), is described and illustrated as a locally endemic species. It is related to Ornithogalum montanum, O. atticum and O. pumilum, however, it differs from these in having wrinkled and corrugated leaf surface, fruiting pedicels thickened at base, flexuose rachis of infructescence and winged capsules. The relationships between the new species and the aforementioned are discussed, while information regarding its ecology, conservation status and karyotype is also given.

Ornithogalum christiniae sp. nov. (Asparagaceae).
 (A) Plant habit at the stage of anthesis. (B) plant habit at the stage of fruit, (C) flower shape (apical and bottom view),
(D) leaf surface structure showing the differences between O. montanum leaf (left) and O. christiniae leaf (right).

Ornithogalum christiniae sp. nov. 

Diagnosis: A species showing some similarities with O. montanum, and to a lesser extent with O. atticum and O. pumilum, in having bulbs with concrescent scales, leaves more than 5 mm wide without a white stripe, a short raceme that is corymbiform at anthesis, entire filaments and hypogeal germination, however, it differs from these three species in having spherical to sub-spherical bulbs, wrinkled and corrugated leaf surface, basally thickened fruiting pedicel and winged capsules.
