A phylogenetic tree is also called an evolutionary tree and it shows the evolutionary relationships that exists among organisms called taxa based on their physical or genetic similarities and differences. The Phylogenetic tree consists of ingroup and outgroup. The ingroup consists of a group of closely related organisms or taxon while the outgroup represents a more distantly related group of organisms or taxon but as close as possible to the ingroup.
The Lily represents the outgroup in the phylogenetic tree while the Orchid are the ingroup. This is because the Lily is distantly related to the orchid.
