摘要

单子叶大化石Desmiophyllum sp. α Seward & Conway被认为在表皮特征和气孔雕刻上与几个新西兰和Mascarene的Cordyline物种接近。然而，由于化石不能明确地放置在虫草属，它被分配到一个新的形式属Paracordyline p.k erguelensis，与现存的顶生木本单叶虫草属(lomandracae)有亲缘关系。

Paracordyline kerguelensis, an Oligocene monocotyledon macrofossil from the Kerguélen Islands

The monocotyledon macrofossil Desmiophyllum sp. α Seward & Conway is recognised as being close in its cuticular features and stomatal sculpturing to several New Zealand and Mascarene species of Cordyline. However, because the fossil cannot be placed unequivocally in Cordyline it is assigned to a new form genus Paracordyline as P. kerguelensis with affinities to the extant aborescent woody monocot Cordyline (Lomandraceae).

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.
