جزییات کتاب
Species descriptions are arranged by family rather than by island to avoid duplication when one species occurs on more than one island.
The islands dealt with in this volume cover a wide range of climatic zones:
The tropical islands have temperature ranges between 23 and 29°C, with 80–90% constant humidity and an annual rainfall of 2 000–2 500 mm falling mainly between December and April during monsoonal storms. Many of the islands are tiny coral atolls, some with volcanic origins. The vegetation is varied, ranging from rainforest (some with lianes and epiphytes) to grassland and seagrass meadows.The subantarctic islands have temperatures constantly near zero degrees, and the annual rainfall is 1 050–1 360 mm usually as light showers on many days of the year. Snow frequently falls and Heard Island is highly glaciated. The vegetation is characterised by fellfield, herbfield, grassland, fen and bog. Heard Island is also significant in containing Australia’s only active volcano.There are 113 families and 495 species treated in this volume. These comprise 95 families of flowering plants, 17 families of ferns and fern allies (whisk ferns, clubmosses), and a single representative of the ancient cycads.
Eleven contributors, three illustrators and eleven photographers from Australia, England, New Zealand and the United States have prepared this volume.
This volume covers 113 families and 495 species. Two new taxa are described, as well as designations of two lectotypes and a neotype.
