The micromorphology of the seeds of species of Ornithogalum genus found in North Africa is studied by SEM. Each species is characterized by a specific ornamentation which gives a high systematic value to this character. The ornamentation of the seed undergoes deep modifications during dessiccation. The supraspecific grouping based on this character do not correspond with the traditional classification of the genus. The phyletic value of this character is discussed.
