Male reproductive structures of Araucaria araucana and Wollemia nobilis (Araucariaceae, Coniferales) in light of conifer evolution

Feddes Repertorium, Volume 135, Issue 4, Page 305-324, December 2024.
Abstract Pollen cones of Araucaria araucana and Wollemia nobilis were investigated. They consist of hundreds of hyposporangiate microsporangiophores with numerous microsporangia, arranged in up to three abaxial rows. Convincing evidence was found that excludes the widely accepted sporophyll concept of coniferous microsporangiophores.

Recognition of the geographical origin and sex of Patagonian forests of Araucaria araucana through the analysis of leaves by FT-NIR: A methodological approach [PDF]

, 2015
Introduction: Plant physiology and growth vary along environmental gradients. Because tree species respond to climate variables and soil properties, these environmental gradients may reflect the chemical or structural leaf compounds.
