Rare: the significant supplement to Brown's magnum opus, the Prodromus. It clarifies some omissions dating back to the voyage of Flinders, but also catalogues the more recent discoveries of luminaries such as Baxter, Caley, Cunningham, Fraser and Sieber. "This was the only addition to Brown's unfinished Prodromus of 1810. Brown took the opportunity presented by all the new Australian material from Allan Cunningham, William Baxter and others to update his account of Proteaceae in his flora and issued this pamphlet. The Supplementum added more than 150 new species of Australian Proteaceae, and Brown discussed the importance of stomatal types of the leaves in this family" (Mabberley).

"Memorable works on Flinders's voyage were published by two scientific members of the expedition: the naturalist Robert Brown and the natural history artist Ferdinand Bauer. After the shipwreck of the 'Porpoise' in 1803 both Brown and Bauer decided to remain in Australia. After spending two years collecting specimens in Van Diemen's Land, Port Phillip, and New South Wales, Brown left the colony in 1805 aboard the newly-repaired 'Investigator'. In 1810 he published in London a famous work, described by his distinguished contemporary Sir William Hooker as 'the greatest botanical work that has ever appeared'. It is an octavo volume, written in Latin, entitled 'Prodromus Florae Novae Hollandiae et Insulae Van-Diemen. Vol. I'. Only the first volume was published, probably because the book was not a commercial success. It is said that of the 250 copies of the first edition that were printed only twenty-six copies were sold. Brown removed the remainder from the market and from then on copies were only available from the author. In 1830 Brown published in London a short octavo volume of 40 pages to supplement the 1810 volume, 'Supplementum primum Prodromi Florae Novae Hollandiae'. Brown's 'Prodromus' and its supplement are of greater interest to collectors of natural history books than to collectors of coastal voyages. Nevertheless, they make an interesting addition to a collection of Flinders material" (Wantrup).
