Integrative taxonomy of the Ceratozamia mexicana Brongn. (Zamiaceae) species complex from a phylogeographic perspective

open access: yesPlant Species Biology, EarlyView.
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.

Breaking the norm: Absence of seed size/seed number trade‐off in Hymanaea stigonocarpa, a tree species from the Brazilian semi‐arid

open access: yesPlant Species Biology, EarlyView.
Seed size/number trade‐off is a central topic in plant biology as it reflects ecological and evolutionary aspects of the species. Here we report the absence of a trade‐off mass/number of seeds and fruits in a polyspermic plant probably associated to abortion of self‐pollinated pistils and flowers.
