Abstract :The concept of mean labeling was introduced by Somasundaram and Ponraj [26]. Different kinds of mean labeling are further studied by Gayathri and Gopi [9-17]. Swaminathan and Sekar [28] introduced the concept of modulo three graceful labeling. As an analogue Jayanthi and Maheswari [22] introduced one modulo three me an labeling and proved that some standard graphs are one modulo three mean graphs. In [20], we have obtained some necessary conditions and properties for the one modulo three mean labeling. In this paper, we ob tain the one modulo three mean labeling of some family of trees.
