Due to its prolific flower and fruit production, it was introduced into subtropical areas such as Florida and Hawai’i, where it is now naturalized and invasive. In an effort to find sustainable means to control R. tomentosa, a large-scale survey was mounted for biological control organisms.

In China: Phylogeny, Host Range, and Pathogenicity
Persoonia 45, 2020: 101–131 ISSN (Online) 1878-9080 www.ingentaconnect.com/content/nhn/pimj RESEARCH ARTICLE https://doi.org/10.3767/persoonia.2020.45.04 Cryphonectriaceae on Myrtales in China: phylogeny, host range, and pathogenicity W. Wang1,2, G.Q. Li1, Q.L. Liu1, S.F. Chen1,2 Key words Abstract Plantation-grown Eucalyptus (Myrtaceae) and other trees residing in the Myrtales have been widely planted in southern China. These fungal pathogens include species of Cryphonectriaceae that are well-known to cause stem Eucalyptus and branch canker disease on Myrtales trees. During recent disease surveys in southern China, sporocarps with fungal pathogen typical characteristics of Cryphonectriaceae were observed on the surfaces of cankers on the stems and branches host jump of Myrtales trees. In this study, a total of 164 Cryphonectriaceae isolates were identiﬁed based on comparisons of Myrtaceae DNA sequences of the partial conserved nuclear large subunit (LSU) ribosomal DNA, internal transcribed spacer new taxa (ITS) regions including the 5.8S gene of the ribosomal DNA operon, two regions of the β-tubulin (tub2/tub1) gene, plantation forestry and the translation elongation factor 1-alpha (tef1) gene region, as well as their morphological characteristics. The results showed that eight species reside in four genera of Cryphonectriaceae occurring on the genera Eucalyptus, Melastoma (Melastomataceae), Psidium (Myrtaceae), Syzygium (Myrtaceae), and Terminalia (Combretaceae) in Myrtales. These fungal species include Chrysoporthe deuterocubensis, Celoporthe syzygii, Cel. eucalypti, Cel. guang dongensis, Cel. cerciana, a new genus and two new species, as well as one new species of Aurifilum. These new taxa are hereby described as Parvosmorbus gen.

Its colourful flowers make it a popular garden ornamental, with several nurseries currently selling the species in Queensland. Dispersal is via bird-dispersed seeds. Considering the history of the species as a significant weed in Hawaii, Florida and parts of Asia, where it has formed pure stands within native vegetation, it seems reasonable to predict it will become a significant pest in Queensland.

A Survey of Medicinal Plants in Mangrove and Beach Forests from Sating Phra Peninsula, Songkhla Province, Thailand
Journal of Medicinal Plants Research Vol. 6(12), pp. 2421-2437, 30 March, 2012 Available online at http://www.academicjournals.org/JMPR DOI: 10.5897/JMPR11.1395 ISSN 1996-0875 ©2012 Academic Journals Full Length Research Paper A survey of medicinal plants in mangrove and beach forests from sating Phra Peninsula, Songkhla Province, Thailand Oratai Neamsuvan*, Patcharin Singdam, Kornkanok Yingcharoen and Narumon Sengnon Faculty of Traditional Thai Medicine, Prince of Songkla University, Hat yai, 90110, Thailand. Accepted 18 November, 2011 This study aimed to survey medicinal plants in mangrove and beach forests from Sating Phra Peninsula, Songkhla Province. Three representative districts including Sing Ha Nakhon, Sating Phra and Ranode were selected. Semi-structured interview was conducted to six local healers for asking about local names, parts of use, preparation and properties. Plant specimens also were collected. Identification was done and the specimens were deposited at The Prince of Songkla University herbarium (PSU). A total of 110 species belonging to 100 genera and 51 families was found. Among them, 69 species were only found in the beach forests, 35 species were only found in the mangrove forests and 6 species could be found in both areas. Fabaceae was the most important family in term of species used. Herb was the most frequently used habit of plants. Most plant species were used for curing fever (18.52%), skin diseases (10.65%) and gastrointestinal tract problems (10.19%), respectively. Interestingly, 34 species relate to pharmacological activities, while 13 species have never been investigated. Therefore, their biological activity should be investigated to support utilization of herbal medicine.

Received: 12 September 2012; in revised form: 5 October 2012 / Accepted: 18 October 2012 / Published: 30 October 2012 Abstract: The impact of invasive plant species in national parks and forests in Vietnam is undocumented and management plans have yet to be developed. Ten national parks, ranging from uncut to degraded forests located throughout Vietnam, were surveyed for invasive plant species. Transects were set up along roads, trails where local people access park areas, and also tracks through natural forest. Of 134 exotic weeds, 25 were classified as invasive species and the number of invasive species ranged from 8 to 15 per park. An assessment of the risk of invasive species was made for three national parks based on an invasive species assessment protocol. Examples of highly invasive species were Chromolaena odorata and Mimosa diplotricha in Cat Ba National Park (island evergreen secondary forest over limestone); Mimosa pigra, Panicum repens and Eichhornia crassipes in Tram Chim National Park (lowland wetland forest dominated by melaleuca); and C.
