Background and Aims:

The genus Psittacanthus is the largest of the family Loranthaceae, inhabiting temperate and tropical zones of the New World, with a large group of hosts. The objective of this study was to determine the species present in the state of Veracruz, Mexico.

Methods:

The specimens of Psittacanthus collected in Veracruz and deposited in the herbaria ENCB, MEXU and XAL were reviewed. These were identified using keys of taxonomic treatments and floras, supported by collections and observation of the species in the field.

Key results:

It was possible to identify morphological characteristics that allow to differentiate the four species of Psittacanthus distributed in Veracruz. As such, the confusion that existed to distinguish the taxa of this genus in the state could be solved. In addition, a key is presented to differentiate the species, and descriptions, photographs and distribution maps of each of them are presented.

Conclusions:

With this work, it was possible to clarify the confusions among the species of the genus Psittacanthus that are distributed in Veracruz, excluding P. americanus that other authors have cited for the state.
