Abstract

The cheirolepidiaceous conifer Pseudofrenelopsis dalatzensis from the Lower Cretaceous Dalazi Formation. Jilin Province, Northeast China is studied in detail based on abundant material. The gross morphology of vegetative shoots shows a greater variation than previously known. Additional information of microstructure is that the adaxial cuticle from the free part of leaves is also papillate as the abaxial cuticle. The excellent preservation of cuticles allows for the first time in this family to four distinct types of cuticle in ultrastructural level: subsidiary cells, guard cells, epidermal cells with and without papillae. Based on 30 measurements the statistic approach on each type of cell cuticle, i.e. not only the total thickness of the cuticle but also details and proportions of all different layers. A key is provided using a combination of 7 significant ultrastructural characters. These results seem to be very promising for the identity of each taxon within the Cheirolepidiaceae family. The cuticular ultrastructure of this family is characterized by having a cuticle proper A composed of A1 wavy polylamellate layer and A2 granular layer, above the cuticular layer B with B1 fibrillate and B2 granular layers. The importance of ultrastructural characters at different levels of taxonomy and palaeoecology is also discussed. (c) 2008 Elsevier B.V. All rights reserved.
