The Rediscovery of Ceratozamia kuesteriana (Zamiaceae) in Mexico

Brittonia, 1982
Ceratozamia kuesteriana Regel, which was described from material coming from an unspecified Mexican locality and which, after its description, was never recorded in the field, has been found in southern Tamaulipas.Ceratozamia kuesteriana is very closely allied toC. zaragozae Medellin but differs by not having twisted leaves.

A New Species of Ceratozamia (Zamiaceae) from Querétaro and Hidalgo, Mexico

Novon, 1993
A new species, Ceratozamia sabatoi, is described and illustrated. Its closest affinities are with C. kuesteriana from Tamaulipas, but it differs from that species in both cone and leaf morphology. The chromosome number of Ceratozamia sabatoi is 2n = 16, and the karyotype is similar to other species of the genus.

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.
