The determinants of biodiversity patterns can be understood using macroevolutionary
analyses. The integration of fossils into phylogenies offers a deeper understanding of …

The cycad genus Ceratozamia comprises 40 species from Mexico, Guatemala, Belize, and
Honduras, where cycads occur throughout climatically varied montane habitats …

Interconduit pit membranes, which are permeable regions in the primary cell wall that
connect to adjacent conduits, play a crucial role in water relations and the movement of …

Drought‐induced xylem embolism is a primary cause of plant mortality. Although c. 70% of
cycads are threatened by extinction and extant cycads diversified during a period of …

Abstract Background and Aims Cycad is a key lineage to understand the early evolution of
seed plants and their response to past environmental changes. However, tracing the …

Zamia magnifica (Zamiaceae), a new species endemic to Sierra Norte, Oaxaca, Mexico, is
described. Zamia magnifica is characterized by having a rupicolous habit, pendent leaves …

The living fossil metaphor is tightly linked with the cycads. This group of gymnosperms is
supposed to be characterised by long-term morphological stasis, particularly after their peak …

Plant–microbe interactions play a pivotal role in shaping host fitness, especially concerning
chemical defense mechanisms. In cycads, establishing direct correlations between specific …

In the present study, the leaf and scape anatomical features of ten Androsace taxa
distributed in Türkiye were defined to contribute to plant identification. Hand sections from …

Summary Zamia decumbens Calonje, Meerman, MP Griff. & Hoese, a threatened cycad
species from Belize, is showcased and illustrated based on field observations as well as …
