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.

Leaf Axil Anatomy of the Araucariaceae

Australian 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 ...

Development of mucilage cells of Araucaria angustifolia (Araucariaceae)

Protoplasma, 2008
The roles of mucilage cells were investigated through morphological and cytological analysis during leaf development in young Araucaria angustifolia plants. Differentiation began in leaf primordia in the shoot apex, when the young cells underwent a greater increase in volume in comparison with other mesophyll cells.

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 as indicators of climate and paleolatitudes

Review of Palaeobotany and Palynology, 1978
Abstract Mesozoic Araucariaceae dominated in the low-latitude (15–20°N) belt of summer-dry climate. It is suggested, that araucarian forests were the most thermophilous Mesozoic assemblages. There were no equivalents of the modern tropical rain forest.

Rust fungi on araucariaceae

Mycopathologia et Mycologia Applicata, 1968
Aecidium fragiforme &A. balansae, parasites ofAgathis spp. in the Malay Archipelago and New Caledonia, respectively, are similar but separate species. They differ from all other confier-infecting rust fungi in having intra-epidermal spermogonia, and from nearly all others in having cupulate aecia.Caeoma sanctae-crucis onAraucaria in Chile has unique ...

Somatic Embryogenesis in Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae)

2016
This chapter deals with the features of somatic embryogenesis (SE) in Araucaria angustifolia, an endangered and native conifer from south Brazil. In this species SE includes the induction and proliferation of embryogenic cultures composed of pro-embryogenic masses (PEMs), which precede somatic embryos development. A.

A revision of the genus Agathis (Araucariaceae) in Australia.

Brunonia, 1977
The status of the Australian species of Agathis Salisb. is reviewed. Although only three species are involved, there has been a considerable amount of nomenclatural confusion. One new species is described from north Queensland, A. atropurpurea Hyland. A. palmerstonii F. Muell. is a synonym of A. robusta (C. Moore ex F. Muell.) F.M. Bail.
