| A preliminary taxonomic revision of the Early Permian Jambi flora results in a lower number of taxa, a number of new determinations and several new combinations (Dicranophyllum molle (Jongmans & Gothan) comb. nov., Oligocarpia posthumii (Jongmans & Gothan) nov. comb., Callipteridium strictinervis (Jongmans & Gothan) comb. nov.). Cones containing the bicuspidate seeds Tobleria bicuspis are recorded for the first time. The exact stratigraphic position of the Jambi flora is unknown, but brachiopods and fusulinids indicate an Early Permian age. Comparisons with the East Asian Permian floras of the Cathaysian realm indicate that the Jambi palaeoflora can best be compared to a relatively xeric Cathaysian flora, possibly indicative of relatively high... |

| Lower Cretaceous plant fossils are described systematically from marine deposits near Villa de Leiva (Boyaca region, Colombia). Specimens originating from the same localities kept at the Florida Museum of Natural History (Gainesville) were included in the systematic description. The plant fossils belong to the Pteridophyta, the Cycadophyta, the Coniferophyta, and to taxa of uncertain affinity which, following previous authors, are referred to the angiosperms. Two new species of Coniferophyta are described, viz. Cupressinocladus hoedemaekeri sp. nov. and Brachyphyllum winklerprinsii sp. nov. Also, Thuites sutamarchensis Huertas is transferred to the genus Cupressinocladus. Fossil plants, Lower Cretaceous, Leiva Region, Colombia. |

| In 1951, W.J. Jongmans published the description of a small flora from Bintan Island in the Riau Archipelago of Indonesia, based on material from one fossil locality in the Bintan Formation (Late Triassic). The complete fossil plant collection from Bintan includes specimens from four localities, all of which were examined for the first time in this study. Twenty-one taxa were determined, compared to an earlier four, and three earlier determinations were revised. Of these 21 taxa, 14 were attributed to the Bennettitales, including eleven leaf species, one Williamsonia sp., and two other fertile and stem organs. The other components of the flora were limited to twigs and cones of Brachyphyllum sp., leaves of Podozamites sp. and leaves of Nilssonia sp., in... |
