Colouring the Petals of a Graph [PDF]
The Electronic Journal of Combinatorics, 2003 A petal graph is a connected graph $G$ with maximum degree three, minimum degree two, and such that the set of vertices of degree three induces a $2$–regular graph and the set of vertices of degree two induces an empty graph. We prove here that, with the single exception of the graph obtained from the Petersen graph by deleting one vertex, all petal ...

Petal development and elaboration
Journal of Experimental Botany, 2022 Abstract Petals can be simple or elaborate, depending on whether they have complex basic structures and/or highly specialized epidermal modifications. It has been proposed that the independent origin and diversification of elaborate petals have promoted plant–animal interactions and, therefore, the evolutionary radiation of corresponding
