Recent linguistic, morphological, and DNA studies have shown that the Polynesian hibiscus known as kaute—koute, ‘aute, and other cognates—is an undescribed eastern Polynesian Hibiscus species in ...sect. 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.

Clemdendrum in Borneo is revised and a key to the 23 taxa recognized is presented. Confusion surrounding application of certain names and species circumscriptions is dispelled. Two new combinations, ...Clerodendrum japonicum var. bethuneanum and Clerodendrum pubiflorum, are made. Clerodendrum sayapense is a new species from Sabah.

An account of the current state-of-affairs of the taxonomic study of Grewia L. (Malvaceae-Grewioideae) in Madagascar is presented. Grewia capuronii Mabb. and G. madagascariensis Capuron are new names ...for the Malagasy endemics, G. lanceolata Bak., non Miq., and G. discolor Baill., non Fresen., respectively.
The new combinations Acuston perenne (Mill.) Mabb. & Al-Shehbaz and A. perenne subsp. obovatum (Boiss. & Kotschy) Mabb.& Al-Shehbaz are proposed. The nomenclatural history, images of relevant types, ...and detailed descriptions of Acuston Raf. and A. perenne are provided for the first time.
In 1856 John Lindley made the first description of the firecracker flower, Rhytidea bicolor (now known as Dichelostemma ida-maia), naming a William Lobb collection exhibited in London. This binomial, ...despite its obvious priority, was proposed to be relegated to synonymy in Taxon, and is discussed here further.
Thirty-three species of Clerodendrum s.l. and five outgroup genera were included in a sequence analysis of internal transcribed spacers of the nuclear ribosomal DNA. The results of the cladistic ...analysis were compared to and combined with cpDNA restriction site data from a previous study. All molecular data identified four major clades within Clerodendrum s.l. and showed the genus to be polyphyletic. Clerodendrum s.s., minus Konocalyx and Cyclonema, is monophyletic and the genus should be restricted to this group. Cyclonema and Konocalyx form a clade distinct from Clerodendrum s.s., which has been recognized as Rotheca Raf.
