Missouri Botanical Garden's cycad collection: A journey through time
Plant Species Biology, Volume 40, Issue 6, Page 607-624, November 2025.This article summarizes the history of the Missouri Botanical Garden's extensive cycad collection. Some of the specimens currently housed in the living collections date back well over 100 years. Cycads continue to face a myriad of threats in the wild, and their conservation in ex situ collections is of critical importance to assist in their survival ...

Plant Species Biology, Volume 40, Issue 6, Page 530-546, November 2025.Recent research has ignited a renewed interest in Ceratozamia cycads, unveiling their remarkable diversity. While previous studies primarily focused on morphology, this investigation employs a multidisciplinary approach, integrating phylogenetics, morphology, and ecological niches. Our methods identify seven distinct lineages as separate species.
