Abstract
A new peltasperm, Scytophyllum bonettiae sp. nov., is described from the Middle Triassic Cortaderita Formation, San Juan, Argentina. The new species is characterised by having medium to small monopinnate, imparipinnate, lanceolate, bicoherent fronds with a free bipinnate pattern of venation, and lumps on the rachis. Recovered specimens display juvenile to adult foliage. The new taxon, together with other species, characteises late Middle Triassic-early Upper Triassic terrestrial flora from western Argentina.
期刊介绍：
Alcheringa : An Australasian Journal of Palaeontology is the official journal of the Australasian Palaeontologists.
Alcheringa covers all aspects of palaeontology and its ramifications into the earth and biological sciences, including:
Taxonomy-
Biostratigraphy-
Micropalaeontology-
Vertebrate palaeontology-
Palaeobotany-
Palynology-
Palaeobiology-
Palaeoanatomy-
Palaeoecology-
Biostratinomy-
Biogeography-
Chronobiology-
Biogeochemistry-
Palichnology.
Review articles are welcome, and may be solicited from time to time. Thematic issues are also possible. Emphasis is placed on high quality and informative illustration, in both line drawings and photographs. Papers of general significance may receive preference over those of more local interest.
