Floristic composition and comparison of middle Eocene to late Eocene and Oligocene floras in North America

In comparison to the early and middle Eocene, the late Eocene and particularly the Oligocene floral record is sparse in North America. Changing tectonic, environmental and climatic conditions during these times resulted in the development of fewer depositional systems favorable for fossil preservation. Floras are known from the Southeast, the Pacific Northwest and the Rocky Mountains. Each area has a distinct geological history that shaped both the vegetation adjacent to sites of deposition as well as the depositional environments themselves. The floristic change from middle to late Eocene, and then to Oligocene reflects a changing paleoclimate from the thermal maximum to cooler and drier conditions in the late Paleogene. In the present paper, major middle, and then late Eocene and finally Oligocene floras of North America are summarized, with an emphasis on their regional geology, depositional setting, paleoclimate and significant floral elements. The North American occurrences of coryphoid palms (Sabal) and cycads are reviewed in relationship to their biogeographic history. Finally, we suggest several directions for future research that will further illuminate the floristic changes from middle, to late Eocene and Oligocene that occurred in North America

Morphological, anatomical and histochemical characterization of Cuphea carthagenensis (Jacq.) JF Macbr. (Lythraceae)

(Morphological, anatomical and histochemical characterization of Cuphea carthagenensis (Jacq.) J.F. Macbr. (Lythraceae)). Cuphea carthagenensis (Jacq.) J.F. Macbr. is an herb, which occurs preferably in wet places. Amongst other species of the genus, C. carthagenensis is distinguished for its great chemical potential and frequent use in popular medicine. In this study the morphological and anatomical structures were identified, as well as the histochemical characterization was done. Samples of root, stem and leaves were collected from adult plants. This material was processed for anatomical and histochemical analysis in light microscopy and for morphological analysis, in scanning electron microscopy Important morphological and anatomical considerations were added for C. carthagenensis, such as: the occurrence of aerenchymatous phellem with suberized layers; the types of trichomes present in the vegetative organs, the characterization of secretory trichomes, as well as the secreted substances. The groups of secondary metabolites presents in the root, stem and leaf of C. carthagenensis with more intense histochemical reaction were: proanthocyanidins, phenolic compounds, acids polysaccharides (mucilage especially) and lipids.25251752
