Abstract: Allium mongolicum, Allium tenuissimum and Allium ramosum are great favor as wide vegetable in recently. Some experts paid attention to the studies on these three Allium plants, but the study on anatomy character is not reported. According to farming observation and paraffin section method the flower's morphologial and anther's anatomy character of three Allium plants are observed, the results show that the flower's morphological is obvious difference; the pollen's shape is also diversity: Allium mongolicum is semi-round, Allium tenuissimum is ovoid, Allium ramosum is long-ovoid. As for the size of pollen, Allium ramosum is the biggest, the second is Allium mongolicum, and Allium tenuissimum is the smallest. The studies indicate the anther's anatomy character of threes plants and provide further theoretical evident for Allium's classification, relationship determining and reproduction.

Key words: Allium, flowes, anther, morphological and anatomy character
