Fruit Juices of Etcho (Pachycereus pecten-aboriginum) and Giant Cardon (Pachycereus pringlei) are Sources of Health-Promoting Ingredients with Potential Anticancer Properties

Plant Foods for Human Nutrition, 2023
Mexico is one of the main diversification centers of cacti in the world, with more than 500 endemic species, most of which remain nutritionally and functionally uncharacterized. The columnar cacti of the genus Pachycereus comprise five underutilized endemic Mexican species, whose nutraceutical properties have only been studied in the P. weberi species.

Behavior and characterization of Moneilema variolare (Coleoptera: Cerambycidae), a new pest to Pachycereus marginatus

Phytoparasitica, 2021
This study was conducted to elucidate the identification of Moneilema variolare Thomson, 1867, as a new pest to Pachycereus marginatus (DC.) Britton & Rose. Behavior, identification, and damages were investigated for 3 years. Adults emerged from pupal chamber in late winter, and fed on Pachycereus stems.

On the Age and Growth Rate of Giant Cacti: Radiocarbon Dating of the Spines of Cardon (Pachycereus Pringlei)

Canadian Journal of Botany, 2016
The orientation of flowers in columnar cacti has been a subject of great interest to plant biologists. The interpretation of this pattern has invoked warmer temperatures as the underlying factor. In this paper, we describe flower orientation in two populations of Pachycereus pringlei (S.

Taxonomic Revision of Pachycereus (Cactaceae)

Systematic Botany, 2009
A comprehensive taxonomic revision of the genus Pachycereus (Cactaceae, Cactoideae, Pachycereeae) is presented. Pachycereus is characterized by one synapomorphic character, the presence of a narrow interareolar groove, and by the combination of flowering region differentiated with flexible spines, flower with a narrow region between the pericarpel and

Pollen morphology of Pachycereus weberi (Cactaceae): an evaluation of variation in pollen size

Plant Systematics and Evolution, 2012
Pollen morphology within a single plant species has been regarded as a relatively constant trait; it has, thus, been used as a taxonomic character. Numerous palynological studies have described the morphology of pollen from Cactaceae and from other families of plants.
