The Araucariaceae: An evolutionary perspective

open access: yesReview of Palaeobotany and Palynology, 1982
Abstract The Araucariaceae, containing two extant genera, Agathis and Araucaria , is a Southern Hemisphere conifer family with a very resticted present day distribution. Although the group has only a few living species, it was once widespread including numerous taxa in the Northern Hemisphere in the Jurassic Period.

Leaf Axil Anatomy of the Araucariaceae

open access: yesAustralian Journal of Botany, 1987
Well defined, persistent meristems, which possess neither a bud-like organisation nor vascular connections with the central vascular cylinder, were found in the apparently blank leaf axils of six species of Agathis and 13 species of Araucaria. In other conifers, leaf axils of similar external appearance are usually reported to lack, or gradually lose ...

Mesozoic Araucariaceae: Morphology and systematic relationships

Journal of Plant Research, 1994
The Southern Hemisphere conifer family Araucariaceae has a very restricted present day distribution, but was more widespread in the past. The genusAraucaria is represented by good fossil material in both hemispheres as early as the Jurassic, whileAgathis is only known from the Southern Hemisphere beginning in the Cretaceous.

Araucariaceae (Pinopsida): Aspects in palaeobiogeography and palaeobiodiversity in the Mesozoic

Zoologischer Anzeiger, 2007
Abstract The paper examines recent information on the history of the ‘southern hemisphere’ conifer family Araucariaceae and gives supplementary notes to previously published monographs. Important data from the Mesozoic fossil record are presented and summarized to describe the ancient diversity and distribution of Araucariaceae.

Purification and biological effects of Araucaria angustifolia (Araucariaceae) seed lectin

open access: yesBiochemical and Biophysical Research Communications, 2006
This paper describes the purification and characterization of a new N-acetyl-d-glucosamine-specific lectin from Araucaria angustifolia (AaL) seeds (Araucariaceae) and its anti-inflammatory and antibacterial activities. AaL was purified using a combination of affinity chromatography on a chitin column and ion exchange chromatography on Sephacel-DEAE ...

Fossil woods from the Cross Valley Formation (Paleocene of Western Antarctica): Araucariaceae-dominated forests [PDF]

open access: yesReview of Palaeobotany and Palynology, 2015
Fossil woods from Paleocene sediments of the Cross Valley Formation (Seymour Island, Antarctic Peninsula) are anatomically studied in detail. We collected 64 samples represented almost exclusively by conifers (95%). Only three samples of not determinable
