A new name, and notes on extra-floral nectaries, in Lagunaria (Malvaceae, Malvoideae) Naturalis
Craven, L.A.; Miller, C.; White, R.G..
The Australian taxon Lagunaria patersonius subsp. bracteata is raised to specific rank as L. queenslandica, based upon morphological and ecological dissimilarities between it and the autonymic taxon, L. patersonius subsp. patersonius. The latter taxon occurs on the southwest Pacific Ocean islands, Lord Howe and Norfolk Islands. Extra-floral nectaries are reported in Lagunaria, apparently for the first time, and contrasted with those occurring in species of Hibiscus sections Bombicella and Furcaria.
Tipo: Article / Letter to the editor Palavras-chave: Malvaceae; Hibiscus; Lagunaria; Extra-floral nectaries.

Acmena, Acmenosperma, Cleistocalyx, Piliocalyx and Waterhousea formally transferred to Syzygium (Myrtaceae) Naturalis
Craven, L.A.; Biffin, E.; Ashton, P.S..
Based on morphological and molecular data, we have concluded that Acmena, Acmenosperma, Cleistocalyx, Piliocalyx and Waterhousea should be combined with Syzygium. The five genera are formally transferred to Syzygium and new names provided for those of their accepted representatives for which names are as yet not available in Syzygium, with the exception of the New Caledonian members of Piliocalyx as these currently are being revised.

An infrageneric classification of Syzygium (Myrtaceae) Naturalis
Craven, L.A.; Biffin, E..
An infrageneric classification of Syzygium based upon evolutionary relationships as inferred from analyses of nuclear and plastid DNA sequence data, and supported by morphological evidence, is presented. Six subgenera and seven sections are recognised. An identification key is provided and names proposed for two species newly transferred to Syzygium.

Anetholea anisata transferred to, and two new Australian taxa of, Syzygium (Myrtaceae) Naturalis
Craven, L.A.; Biffin, E..
The distinction between Anetholea and Syzygium is lessened due to the occurrence of epigeal germination and dry fruitedness in the latter genus also and it is concluded that Anetholea is better placed within Syzygium. Analysis of sequence data from nuclear ribosomal DNA and the chloroplast genome support this conclusion. The sole species of Anetholea, A. anisata, is transferred to Syzygium and the new combination, S. anisatum (Vickery) Craven & Biffin, made. Syzygium wilsonii subsp. cryptophlebium is reinstated at species rank, necessitating the new combination, S. cryptophlebium (F. Muell.) Craven & Biffin. Two new taxa of Syzygium are described from Australia, S. wilsonii subsp. epigaeum Craven & Biffin and S. maraca Craven & Biffin.

Classification of the Vireya group of Rhododendron (Ericaceae) Naturalis
Craven, L.A.; Goetsch, L.A.; Hall, B.D.; Brown, G.K..
A new classification of the Vireya group of Rhododendron, based upon their evolutionary relationships as inferred from analysis of nuclear and plastid DNA sequence data, is presented. Rhododendron sect. Vireya is not monophyletic and its species are herein placed in three sections within subg. Rhododendron, namely sect. Discovireya, sect. Pseudovireya and sect. Vireya, with two subsections recognised within sect. Vireya: subsect. Euvireya and subsect. Malayovireya. Identification keys are provided.

Diplarche and Menziesia transferred to Rhododendron (Ericaceae) Naturalis
Craven, L.A..
The genera Diplarche and Menziesia have been shown to be nested in Rhododendron based upon cladistic analyses of DNA data. Morphologically, the differences between Diplarche and Menziesia are not so great that their inclusion in Rhododendron is inappropriate and the species of these two genera are formally transferred to Rhododendron. The following new names are proposed: Rhododendron benhallii, R. chamberlainii, R. goyozanense, R. × kamatae, R. katsumatae, R. kroniae, R. menziesii, R. menziesii subsp. glabellum, R. multiflorum, R. multiflorum forma bicolor, R. multiflorum forma brevicalyx, R. multiflorum var. purpureum, R. pentandrum, R. pilosum, R. sophistarum, R. yakushimense.

South Pacific Cleistocalyx transferred to Syzygium (Myrtaceae) Naturalis
Biffin, E.; Craven, L.A.; Tuiwawa, M.; Crisp, M.D.; Gadek, P.A..
Evidence from both morphological and molecular phylogenetic data support the view that the circumscissile calycine calyptra, the sole defining character of Cleistocalyx, has multiple origins within Syzygium s. l. and is therefore an invalid basis for generic circumscription. Accordingly, the Fijian Cleistocalyx are transferred to Syzygium, and the new combinations Syzygium decussatus, S. eugenioides and S. seemannii, are made. Syzygium myrtoides is reinstated, and Cleistocalyx ellipticus, C. longiflorus, C. kasiensis and C. seemannii var. punctatus are reduced to the synonymy of S. seemannii. The distribution of S. seemannii is extended to Vanuatu.

The genus Syzygium (Myrtaceae) in Vanuatu Naturalis
Tuiwawa, S.H.; Craven, L.A.; Sam, C.; Crisp, M.D..
Twenty species of Syzygium occur in Vanuatu of which eighteen are indigenous (six being endemic and one being an ancient introduction) and two are recently introduced. Three species are newly described: S. chanelii, S. flabellum and S. vanuatuense. The Syzygium flora of Vanuatu has strong links at species level to that of the Solomon Islands and Fiji, less strong links to elsewhere in the southwest Pacific and apparently no links to New Caledonia. Descriptions are provided for each species occurring in Vanuatu and identification keys are provided for flowering and vegetative material.

The Hibiscus panduriformis complex (Malvaceae) in Australia Naturalis
Juswara, L.S.; Craven, L.A..
The Hibiscus panduriformis Burm.f. species complex in Australia is revised. Six species are recognised, of which one is the widespread H. panduriformis; one, H. austrinus, is based upon H. panduriformis var. australis; and four represent new species, H. apodus, H. calcicola, H. fluvialis, and H. multilobatus. A new variety is recognised in H. austrinus, namely var. occidentalis. Distribution maps are provided for all taxa and an exsiccatae list is included.

Vireya Rhododendrons: their monophyly and classification (Ericaceae, Rhododendron section Schistanthe) Naturalis
Craven, L.A.; Danet, F.; Veldkamp, J.F.; Goetsch, L.A.; Hall, B.D..
Further investigation into the evolutionary relationships of the vireya group of Rhododendron, utilising nuclear DNA sequence data, has demonstrated that this group of species is monophyletic, and a revised classification is presented. The name Vireya is predated at sectional level by several other valid names and the correct name for the section is now Schistanthe. Within Schistanthe, four subsections are recognised: Discovireya, Euvireya, Malayovireya and Pseudovireya. Revised identification keys are provided. Some morphological features of value for classification and/or species delimitation are briefly discussed.
Tipo: Article / Letter to the editor Palavras-chave: Classification; Ericaceae; Key innovations; Morphology; Rhododendron; Schistanthe; Vireya.
