When dealing with the taxonomy of Pacific coastal species within the region of New Caledonia and Vanuatu, one should examine all names published in Australasia and other Pacific islands. When the putative new species is also closely related to a highly praised ornamental species with many cultigens and with many old horticultural names, the task becomes more arduous. This is the case for the new species we describe as Gâteblé, Ramon & Butaud, which is closely related to the now pantropical cultivated species (Seem.) Guillaumin s.l. Compared to , has carnose and shiny leaves, pedicels and sepals covered with glandular hairs, a short and enlarged corolla tube and can produce fertile capsules. The new species is a coastal taxon occurring naturally in the Melanesian archipelagos of New Caledonia and Vanuatu. This species seems uncommon in the Loyalty Islands but more common in the archipelago of Vanuatu and we propose it as Critically Endangered in New Caledonia, Vulnerable in Vanuatu and Least Concern when the IUCN evaluation is done globally.
在处理新喀里多尼亚和瓦努阿图地区太平洋沿岸物种的分类时，需要研究在澳大拉西亚及其他太平洋岛屿上发表的所有名称。当假定的新物种还与一种备受赞誉、有许多栽培品种且有众多古老园艺名称的观赏物种密切相关时，这项任务就变得更加艰巨。我们描述的新物种Gâteblé, Ramon & Butaud就是这种情况，它与如今在泛热带地区栽培的物种（Seem.）Guillaumin s.l.密切相关。与（该栽培物种）相比，Gâteblé有肉质且有光泽的叶子，花梗和萼片上覆盖着腺毛，花冠管短且膨大，并且能产生可育的蒴果。这个新物种是一个沿海分类群，自然分布于新喀里多尼亚和瓦努阿图的美拉尼西亚群岛。该物种在洛亚蒂群岛似乎不常见，但在瓦努阿图群岛更为常见，我们建议将其在新喀里多尼亚列为极危，在瓦努阿图列为易危，在全球进行世界自然保护联盟评估时列为无危。
