Fossils of an endangered, endemic, giant dipterocarp species open a historical portal into Borneo's vanishing rainforests. [PDF]
Am J BotAbstract Premise Asia's wet tropical forests face a severe biodiversity crisis, but few fossils record their evolutionary history. We recently discovered in situ cuticles on fossil leaves, attributed to the giant rainforest tree Dryobalanops of the iconic Dipterocarpaceae family, from the Plio‐Pleistocene of Brunei Darussalam (northern Borneo ...

Stamen Morphology in Nothofagus (Nothofagaceae) [PDF]
International Journal of Plant Sciences, 1998 Stamen morphology is shown to vary considerably in Nothofagus. All species in subgenus Brassospora have heteromorphic, striated epidermal papillae on their anthers. The absence of similar epidermal papillae in other subgenera in Nothofagus or in the putative sister taxa Fagaceae or Betulaceae would suggest that heteromorphic papillae is a derived ...

Axis Differentiation in Two South American Nothofagus Species (Nothofagaceae) [PDF]
Annals of Botany, 2003 An analysis was carried out on the length, diameter and number of leaves, and the ratios between these variables for current-year growth units (sibling growth units) derived from different nodes of previous-year growth units (parent growth units) of young Nothofagus dombeyi and Nothofagus pumilio trees.
