Novae Hollandiae Plantarum Specimen

Published between 1804 and 1806, it is one of the earliest works to describe the plants of the continent;[1] according to Denis and Maisie Carr, "[i]n practical terms, this was the first general flora of Australia.

[5][6] The preface describes the journey "from Cape of Good Hope to Australia", an example of the continent being named as 'Australia' before its popularisation by Flinders' use in A Voyage to Terra Australis.

[8] This work featured the first descriptions of Cephalotus follicularis,[9] a carnivorous plant, and species Adenanthos obovatus and Gahnia trifida from the southern coast.

The collections made at southwest Australia also produced new genera Adenanthos (Proteaceae) and Calytrix (Myrtaceae), species Astartea fascicularis, Hakea clavata and Taxandria marginata, and the first description of the now widely introduced Acacia saligna.

[6] The first confirmed collection of Australian bryophytes are described and illustrated by the author; the current name for these species are the mosses Cyathophorum bulbosum and Hypnodendron comosum and a liverwort Hymenophyton flabellatum.
