A taxonomic revision of Zamia montana and Zamia oligodonta, with notes on their conservation status
Phytotaxa, 2015 The taxonomy of Zamia montana and Z. oligodonta, two poorly understood species occurring at high elevations in the Western Cordillera of Colombia, is discussed. Zamia oligodonta was recently synonymized under Z. montana, but information derived from recent field studies is provided showing the two species are quite distinct. A treatment of both species

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 ...

A first characterization of the leaflet endophytic prokaryotic community in Dioon cycads
Plant Species Biology, Volume 40, Issue 6, Page 547-555, November 2025.This study presents the first characterization of leaflet endophytic prokaryotic communities in Mexican cycads of the genus Dioon. Using 16S rRNA metabarcoding, we describe the composition and diversity of foliar bacterial communities across species and biogeographic regions, highlighting patterns potentially shaped by environmental conditions.

Plant Species Biology, Volume 40, Issue 6, Page 572-583, November 2025.Spatial distribution pattern were studied for Ceratozamia fuscoviridis, an endangered species in Mexico, based on Ripley's K t and K 12 analysis. Clumped spatial distribution patters was found in individuals of all populations, suggesting low interaction with predators/dispersers and/or evidence of suitable microsites for cycads.

Best in the company of nearby males: female success in the threatened cycad, Zamia portoricensis [PDF]
PeerJ, 2018 Variation in plant reproductive success is affected by ecological conditions including the proximity of potential mates. We address the hypothesis that spatial distribution of sexes affects female reproductive success (RS) in the dioecious cycad, Zamia ...

Progress in the study of dioecy in Mexican cycad species and its implications for conservation
Plant Species Biology, Volume 40, Issue 6, Page 556-571, November 2025.Cycads are endangered dioecious plants of great ornamental value that have a long period of sexual maturity. Therefore, it is crucial to have methods for early sex determination that can help to develop effective strategies for their conservation. Abstract Dioecy is a system of sexual reproduction in plants, characterized by the spatial separation of ...
