Cactus Habitus: Hunting Trichocereus in the Americas

This presentation reflects on Fahim’s journeys through Peru, Bolivia, and Argentina in search of new and exceptional Trichocereus varieties, particularly T. peruvianus, T. pachanoi, T. bridgesii, and T. terscheckii. Trekking across the Andes Mountains, Fahim documented striking wild specimens growing in their native habitats, capturing their ecological diversity, form, and resilience in situ.

Beyond botanical fieldwork, Fahim’s travels involved rich engagement with local ethnobotanical practices, ranging from traditional San Pedro use to contemporary adaptations. Through these encounters, he gained deeper insight into the cultural and spiritual significance of Trichocereus across regions and communities, observing how ancient traditions continue to evolve within modern contexts.

A highlight of the journey was a visit to Chavín de Huántar in Peru, one of the most important archaeological and ethnobotanical sites associated with San Pedro ritual use. There, Fahim participated in a modern interpretation of a traditional ceremony, exploring how spirituality, history, and plant knowledge converge. In Argentina, he also interviewed T. terscheckii consumers engaging in a contemporary practice inspired by the traditional use of San Pedro species.

With support from cactus experts including Carlo Brescia, Arthur Dempsey, and Zuzanka Knize, this journey proved a remarkable and unforgettable foray into medicinal cactus ethnobotany. Blending travel narrative, field documentation, and cultural reflection, this presentation sits at the intersection of science, tradition, and adventure. Fahim highlights the beauty and diversity of Trichocereus in habitat while inviting reflection on how outsiders might engage respectfully with these living traditions.
