The Flora Novae-Zelandiae is a description of the plants discovered in New Zealand during the Ross expedition written by Joseph Dalton Hooker and published by Reeve Brothers in London between 1853 and 1855.
On 12 May the ships anchored at Christmas Harbour for two and a half months, during which all the plant species previously encountered by James Cook on the Kerguelen Islands were collected.
[5] Large floating forests of Macrocystis and Durvillaea were found until the ships ran into icebergs at latitude 61° S. Pack-ice was met at 68° S and longitude 175°.
The flora proper begins with a short introduction explaining the book's approach; as with the other volumes, the bulk of the text is a systematic account of the families and species found by the expedition.
David Frodin commented in 2001 that J. D. Hooker was the first to study the sub-Antarctic Campbell Island and the Auckland group, and that the Flora "largely completed" the "primary phase of botanical survey in the [New Zealand] region".
