Araucariales: Agathaceae
from Part III - Living Arborescent Gymnosperm Genetic Presentations
Published online by Cambridge University Press: 11 November 2024
Tall to extremely tall and ultimately highly majestic mostly tropical lowland rainforest trees, to 30–60+ m when mature, usually eventually with an unbranched, typically straight and clear trunk for two-thirds of more of the height of the tree. They bear a large to sometimes massive evergreen crown, typically emergent high above surrounding broadleaf rainforest canopies. The presence of fallen large, leathery, stalked multi-veined leaves, elongate–cylindrical red–brown male cones and free, winged seeds fallen from dismembering female cones, all typically shed whole to the forest floor from high tree canopies, confirms the presence of Agathis, and distinguishes Agathis from other resinifera and from surrounding broadleaves.
