A phylogenetic analysis of Acacia subg. Phyllodineae sect. Botrycephalae, endemic to eastern Australia, is presented based on a combined dataset of ITS and ETS sequences of nrDNA. A smaller set of species was sequenced also for the cpDNA trnK region. A limited number of morphological characters was also combined with the ITS+ETS dataset for most taxa. Thirty-eight of 41 Botrycephalae species were sequenced, together with a sample of ten uninerved phyllodinous species (sect. Phyllodineae). Although these DNA regions showed limited sequence divergence, bootstrap supported nodes of the consensus ITS+ETS tree indicate that Botrycephalae as currently defined is polyphyletic. Eight bipinnate species fell outside the main clade of Botrycephalae species while seven phyllodinous species were nested within it, near the base. The few derived but homoplasious morphological characters that were discovered included: presence of appressed unicellular hairs, presence of jugary and interjugary glands, number of pinnae > 7 and the funicle half–fully encircling the seed. Section Botrycephalae requires redefinition.
Bogor Botanic Gardens (BBG) was established in 1817 and is the oldest botanic garden in South East Asia. The garden has long been a centre for scientific research and has been the founding institution of a number of other research centres in Indonesia, particularly in the life sciences. The garden initially covered 47 ha but has expanded over the years and is now 87 ha. It has evolved over its 200-year history from a collection of economically valuable plants to the multi-faceted institute it is today, undertaking activities in plant conservation, research, education, ecotourism and environmental services. In recent years, it has strengthened its role in plant conservation through the establishment of 32 new botanic gardens across Indonesia. These new gardens are managed by local government and universities and supervised by BBG. In its bicentenary year, 2017, BBG organised a number of activities, programmes and celebrations and these are highlighted in thisarticle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
