Geissois is a genus of trees and shrubs in the plant family Cunoniaceae. It includes about 19 species mostly found in New Caledonia, but also in Fiji, Vanuatu, and the Solomon Islands. Leaves are opposite, palmate with 3-9 leaflets, with entire margin (serrate in Geissois hirsuta and juveniles) and intrapetiolar stipules. The inflorescences are simple racemes (trident in Geissois hirsuta ) and bottle-brush like. The flowers have four red sepals, lacking petals, with many long red stamens. The fruit is a capsule, the seeds flat and winged. The genus includes several nickel hyperaccumulator (most species occurring on ultramafic rocks) [2] [3] and one aluminum hyperaccumulator, Geissois polyphylla . [3]

Two species from Australia formerly placed in this genus have now been transferred to the genus Karrabina . [1]

Flore de la Nouvelle-Calédonie is an ongoing multi-volume flora describing the vascular plants of New Caledonia in the South-West Pacific. published by the National Museum of Natural History in Paris since 1967. Each species treatment typically includes taxonomic information, morphological description, a line drawing and a distribution map. Originally published as Flore de la Nouvelle-Calédonie et Dépendances, since 2014 it has been renamed shortly Flore de la Nouvelle-Calédonie and is co-published with Institut de Recherche pour le Développement in a fully colored format. Flore de la Nouvelle-Calédonie currently consists of 27 volumes, covering little over 50% of a total of approximately 3,400 species native to the New Caledonian archipelago. Major botanical families awaiting treatment include Rubiaceae, Cyperaceae, Rutaceae, and Poaceae.
