Let be a graph with vertex set and edge set . A vertex labelling induces an edge labelling defined by . Let denote the number of vertices with and respectively. Let be similarly defined. A graph is said to be cordial if there exists a vertex labeling such that and . In this paper, we show that for every positive integer and the following families are cordial: (1) Helms . (2) Flower graphs . (3) Gear graphs . (4) Sunflower graphs . (5) Closed helms . (6) Generalised closed helms . (7) Generalised webs .
