Abstract
Seeds belonging to seven monocot species belonging to three families; Asparagaceae, Asphodelaceaae and Colchiaceae; are investigated using both stereo-and scanning microscopes. From the studied seed characters, the data obtained revealed that the tri-locular monocot taxa shared most of the floral characters, in spite of the differences in the inflorescences. Seed macro-morphological characters aid some information which can be used in the identification of the species, but the micro-characters are more valuable in the taxonomy of the taxa. Hilum shape and length beside the micropyle position are valuable characters in monocot classification. In this work, the hilum length varied greatly from 0.3 mm in both Leopoldia camosa and Asphodelus ramosus to 1.5mm in Colchium cornigulata. With three different shapes; linear, oval or even circular; and two micropyle position either lateral or central. These characters can help in the discrimination of the studied taxa and consider from the first observable ones within the monocots.
