Lilibiscus. It is described here as Hibiscus kaute L.A.J. Thomson & Butaud, and appears to be extremely rare, if not extinct in the wild. The French botanist Jean Nadeaud (1873) recorded ‘aute in a wild state during the 1850s at the end of Pirae valley (Nahoata) and elsewhere in the interior of Tahiti where it grew on cliff faces. The original wild form—with a single whorl of petals—is also rare in cultivation, both in French Polynesia and elsewhere in the South Pacific Islands. The medicinal Polynesian double-flowered form is uncommon in cultivation and often mistaken for recently-introduced cultivars. As well as being of great cultural importance to Polynesians, kaute is arguably the most significant species in the development of modern Hibiscus hybrids and a missing link in understanding the origins of H. rosa-sinensis. Ex situ conservation measures are urgently needed in French Polynesia (Tahiti and Marquesas Islands) and, internationally, in botanic gardens, for this important progenitor species of Lilibiscus hybrids."

Thomson sp. nov. and H. × denisonii Burb. Auteurs : Lex A.J. Thomson, Auteur ; Luca Braglia, Auteur ; Brock Mashburn, Auteur ; Jean-François Butaud, Auteur ; Stuart Read, Auteur Année de publication : 2023 Article en page(s) : pp. 49-61 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Hibiscus [Thèmes] Conservation [Thèmes] Jardin botanique Mots-clés : Hibiscus denisonii  Hibiscus mabberleyi Résumé : "Hibiscus denisonii Burb. came to international attention in English horticulture in 1876, having been sourced from Australian gardens, and generally believed to have come from the South Pacific Islands. It was described as a distinctive creamy white-flowered hibiscus with thick-leathery, dark-green, ‘ivy-like’ leaves that were different from those of other hibiscus then in cultivation. Burbidge’s H. denisonii has a hybrid origin and appears to have almost vanished from cultivation, aside from a morphologically matching hibiscus of undocumented origin growing in the Jardín de Aclimatación de la Orotava, Tenerife, Canary Islands. The name Hibiscus denisonii has long been associated with a similar white to light pink flowered hibiscus species, under cultivation in European botanical gardens, and here described as Hibiscus mabberleyi L.A.J. Thomson. Hibiscus mabberleyi is distinguished from H. × denisonii by its thinner, more slender and hirsute leaves; a more open, upright growth habit and characteristic breeding true-to-type from selfed seed. The genetic affinities of H. mabberleyi are with Mascarene Islands species in sect. Lilibiscus including H. boryanus DC., H. fragilis DC., H. genevei Bojer and and H. liliiflorus Cav. Recommendations are made for further research and ex situ conservation of H. mabberleyi."
