What is Ceratozamia brevifrons (Zamiaceae)?

Brittonia, 2012
The taxonomic status of the Mexican cycad Ceratozamia brevifrons is reassessed based on information from habitat, herbaria and living collections in the Botanic Garden ‘Jardin Botanico Francisco Javier Clavijero.’ Comparison of gross morphology of C. brevifrons with that of C.

Another new species of Ceratozamia (Zamiaceae) from Chiapas, Mexico

Botanical Journal of the Linnean Society, 2001
Ceratozamia mirandai sp. nov. from the Sepultura Biosphere reserve of Chiapas, Mexico, is described and illustrated. Its closest affinities are with C. kuesteriana Regel from Tamaulipas of north-east Mexico, but differs in male and female cone and trunk morphology.

Structural investigation of Ceratozamia spinosa mucilage

Carbohydrate Research, 1994
The polysaccharide fraction from Ceratozamia spinosa appears to be made up mainly by a chemically homogeneous polysaccharide but with a wide range of molecular weight. By NMR and chemical degradative methods, it is shown to consist essentially of a backbone of alternate-->4)-beta-D-GlcpA-(1-->and-->2)-alpha-D-Manp-(1--> units.

Evolution of Ceratozamia cycads: A proximate-ultimate approach

Molecular Phylogenetics and Evolution, 2019
Evidence suggests that past climatic fluctuations affected speciation of extant cycads. However, empirical genetic and morphological evidence explaining patterns and processes of species diversification are scarce. There are some explanations for the origin and evolution of the genus Ceratozamia, but with inconclusive results.

A New Species of Ceratozamia (Zamiaceae) from Chiapas, Mexico

Brittonia, 1982
Ceratozamia norstogii sp. nov. from Chiapas, Mexico is described. This species is distinct from all others in the genus in that it has a straight rachis with very narrow leaflets (3–10 mm wide) which are strongly curved and almost round in cross section when dried. It is known only from Chiapas, Mexico and in cultivation.

Morphology of Ceratozamia

Botanical Gazette, 1912
1. Ceratozamia mexicana grows best in well shaded mesophytic conditions. 2. Any individual in passing from the seedling to the adult stage shows such a progressive change in its leaves, the leaflets becoming larger, broader, thicker, and more numerous, that descriptions of species based largely upon leaves are open to suspicion. 3.
