Stomatal development in the cycad family Zamiaceae [PDF]
Annals of Botany, 2021 Abstract Background and Aims The gymnosperm order Cycadales is pivotal to our understanding of seed-plant phylogeny because of its phylogenetic placement close to the root node of extant spermatophytes and its combination of both derived and plesiomorphic character states. Although widely considered a

Monograph of Ceratozamia (Zamiaceae, Cycadales): an endangered genus [PDF]
PhytoKeys, 2022 Ceratozamia (Zamiaceae, Cycadales), is a member one of the most endangered seed plant groups. Species of Ceratozamia grow from near sea level up to 2,100 meters in Mexico and Mesoamerica. We present a modern taxonomic treatment of Ceratozamia, based on fieldwork combined with detailed study of herbarium specimens in and from Mexico and Central America.

What is Ceratozamia mexicana (Zamiaceae)? [PDF]
Botanical Sciences, 2016 Explorations in central Veracruz on the Transvolcanic Mexican Belt and regions explored by 19th century botanists we found various populations of Ceratozamia whose taxonomic status is not yet completely clear. Especially two populations of C. mexicana with distinct morphology; one population at El Esquilón considered as C. mexicana by Chamberlain

A checklist of gymnosperm-feeding leafminers (Arthopoda, Insecta) in North America and Europe [PDF]
Biodiversity Data Journal, 2022 The leafminers on gymnosperms receive much less attention than those on either angiosperms or ferns. Given the distinctly different leaf shape and leaf venation found in gymnosperms, they would be expected to host significantly different leafminer groups.
