Abstract

Ornithogalum umbratile (Sect. Ornithogalum), a new endemic species from Gargano (Apulia, Italy), is described on the basis of morphological, palynological and karyological characters as well as ecological tolerances. The species is usually hexaploid (2n = 54 + 0-4 accessory chromosomes), but occasionally heptaploid (2n = 63 + 1B). Differences with allied Italian taxa, especially O. etruscum, are discussed.
