“…This result was also consistent with a previous ITS study (Brown et al 2001), and it is argued that all species of the tribe should be included within Melaleuca (Edwards et al 2010). Similarly, molecular and morphological data have been used to argue that five genera in the tribe Syzygieae would be better placed within the large genus Syzygium (Craven 2006;Craven and Biffin 2005;Parnell et al 2007). A subsequent nuclear and plastid DNA sequence phylogeny has recently resulted in the recognition of six subgenera and seven sections within Syzygium .…”

“…Generic limits in the tribe Melaleuceae have been the subject of much recent study (Brown et al 2000, Wilson et al 2005, Craven 2006, Edwards et al 2010, Udovicic and Spencer 2012, Craven et al 2014.

“…Many alien taxa are underrepresented, remain unidentified for considerable periods of time, or are misidentified in herbaria (Pyšek et al 2013). In this paper we explore the scale of this problem using taxa in the genus Melaleuca (sensu Craven (2006) and Brophy et al (2013)) in South Africa as a case study.…”

“…As a result of debate surrounding generic limits in the tribe Melaleuceae, especially regarding the recognition of Callistemon as a segregate genus (Craven 2006;Udovicic and Spencer 2012, Edwards et al 2010, Craven et al 2014, species lists included in the recently published Alien and Invasive Species Regulations in South Africa (DEA 2014) may generate errors due to synonymy issues. For example, the regulations list Callistemon rigidus, which is now treated as a synonym of C. linearis if one accepts the separation of the two genera (see Council of Heads of Australasian Herbaria 2016); if a broad concept of Melaleuca is adopted, then the taxon should be listed as Melaleuca linearis.…”

Introduced species lists provide essential background information for biological invasions research and management. The compilation of these lists is, however, prone to a variety of errors. We highlight the frequency and consequences of such errors using introduced Melaleuca (sensu lato, including Callistemon) species in South Africa as a case study. We examined 111 herbarium specimens from South Africa and noted the categories and sub-categories of errors that occurred in identification. We also used information from herbarium specimens and distribution data collected in the field to determine whether a species was introduced, naturalized and invasive. We found that 72% of the specimens were not named correctly. These were due to human error (70%) (misidentification, and improved identifications) and species identification problems (30%) (synonyms arising from inclusion of Callistemon, and unresolved taxonomy). At least 36 Melaleuca species have been introduced to South Africa, and field observations indicate that ten of these have naturalized, including five that are invasive. While most of the errors likely have negligible impact on management, we highlight one case where incorrect identification lead to an inappropriate management approach and some instances of errors in published lists. Invasive species lists need to be carefully reviewed to minimise errors, and herbarium specimens supported by DNA identification are required where identification using morphological features is particularly challenging.

With about 335 species, the tribe Melaleuceae comprises a major lineage within the Australian Myrtaceae. Here we investigate relationships within Melaleuceae using cpDNA sequences (ndh)F and 27 morphological characters. We find strong evidence for the non–monophyly of Melaleuca, with all other currently recognized genera of Melaleuceae (Beaufortia, Calothamnus, Conothamnus, Eremaea, Lamarchea, Petraeomyrtus, Phymatocarpus, Regelia) falling within that genus. Our findings are broadly consistent with previous studies using nuclear ITS DNA sequence data; however, the cpDNA phylogeny estimate is more resolved and has higher support for major nodes. Melaleuceae is found to comprise three major clades, each containing species of Melaleuca and each with good support. The M. leucadendra (broad–leaf paper–barks), M. uncinata, M. pungens and M. acacioides groups, New Caledonian callistemons, and all other currently recognized genera of Melaleuceae form one clade. Australian Callistemon species, which have been synonymised recently with Melaleuca, cluster within a second clade of Melaleuca that includes the M. fulgens, M. laxiflora and M. ordinifolia groups, and some members of the M. lanceolata and M. cuticularis groups. A third clade includes other members of the M. lanceolata and M. cuticularis groups, M. foliolosa and the M. huegelii group. No morphological support or diagnostic synapomorphies are identified for any of these clades. Together with previous studies, our findings indicate that the circumscription of Melaleuca, and the generic status of other genera within Melaleuceae, is poorly supported, and we propose that all genera within the Melaleuceae are synonymised with Melaleuca.
