The molecular revolution has given us new opportunities to explore species relationships, evolution and historical biogeography. It is at its most powerful when combined with studies of the living plants in the field and information gleaned from the many thousands of herbarium specimens that go into preparing comprehensive taxonomic revisions.For the genus Aglaia, a genus of more than 100 species, morphological, distributional and biological information has been combined with the history of plate tectonics in the Indo-Malayan Australasian Archipelago, molecular phylogenies and historical biogeographical analyses. Hypotheses for the origin, expansion and species radiation since its origin c. 24 million years ago have been proposed. The tribe Aglaieae was the first monophyletic plant group for which a fully resolved, fossil-dated phylogenetic tree was published. Subsequent studies of some other groups of plants and animals have revealed similar patterns of dispersal, establishment and radiation in the region. The comprehensive nature of the research carried out on this medium-sized genus of tropical rain forest trees has contributed and continues to contribute to an understanding of the Sunda-Sahul floristic interchange and the species radiation that follows dispersal between these continental shelves.The genus is found mainly in lowland tropical rain forests from the Western Ghats of India to Samoa and from southern China to tropical Australia, with its greatest diversity in Malesia. In SE Asia section Aglaia is dispersed by mammals, especially greater and lesser apes (orang-utan, siamang and gibbons). This section of the genus has diversified in New Guinea without its primate dispersers and with no obvious alternative disperser. No marsupial is known to be an efficient seed-disperser. The other two sections of the genus, section Amoora and section Neoaglaia, are bird-dispersed. The coastal and estuarine species, Aglaia cucullata, almost certainly sometimes survives a sea journey. This may partly explain its morphological uniformity over a wide geographical area, from Bangladesh to New Guinea.

An investigation into the reproductive biology of Medinilla multiflora Merr. (Melastomataceae) from Mt Makiling, Luzon, is presented. This includes a morphological and distributional examination of the population on the mountain, the documentation of reproductive phenological patterns, a study of the mating system and observations of biotic interactions. Measurements were made of trait variability, reproductive phenology was characterised from field and herbarium observations, stigmatic receptivity was tested by counting pollen germination, insect exclusion and hand-pollination experiments helped determine the mating system and field observations recorded the identity and behaviour of floral visitors. Significant reproductive morphological differences were found between described populations. This identified a need for the recognition of this diversity and further delimitation of the Medinilla multiflora species complex. Although Medinilla multiflora produced flowers and fruit year-round, the population also exhibited cycles of increased reproduction most likely initiated by seasonal low temperatures. Medinilla multiflora was found to require pollination but not cross-pollination. Two major peaks in stigmatic receptivity occurred throughout the day and the majority of pollen was found to be viable. Generalist bees proved to be the primary pollinators of the study population and were most active in the morning depending on weather conditions. Generalist pollinators and self-compatibility are advantageous traits for establishment and persistence in isolated mountain habitats; however, losses of this habitat due to climate change could have profound consequences for the future success of Medinilla multiflora.

Large-scale genetic structure revealed in tree populations in SE Asia, as well as in many temperate forests, has been shaped by climatic fluctuation in the late Pleistocene, most importantly by that in the last glacial period. In a comparative study of the phylogeographic patterns of two closely related dipterocarp species, Dryobalanops aromatica C.F.Gaertn. and D. beccarii Dyer, we investigated how changes in land area associated with changes in climate affected large-scale genetic structure. We examined the genetic variation of D. aromatica, collected from nine populations throughout the Sundaic region, and of D. beccarii, collected from 16 populations mainly in Borneo, using seven polymorphic microsatellite markers. The two species were clearly distinguishable in the STRUCTURE analysis, although hybridisation probably occurred in sympatric populations and also in several other populations. The D. aromatica populations were divided into two main groups by the STRUCTURE analysis: Malay–Sumatra and Borneo. Mixing of the Sumatra and Borneo clusters occurred on the Malay Peninsula, supporting the hypothesis that tropical rainforests expanded over a dried Sunda Shelf during the last glacial period. The two main genetic clusters might have been formed by repeated cycles of fluctuation in land area. The D. beccarii populations in Borneo were divided into four geographically distinct groups: western Sarawak, central inland Sarawak, central coastal Sarawak and Sabah. The population on the Malay Peninsula (Gunung Panti) was an admixture of the four Bornean clusters. This suggests that this population is a relic of the recent range expansion of D. beccarii during the last glacial period.

The need to exploit limestone products for national development impacts on the conservation of rare and endangered limestone species. To minimise this impact it is necessary to identify which of the 570 limestone outcrops have high conservation importance and whether they have narrowly endemic and/or endangered limestone species. In the absence of detailed checklists for each outcrop, the Gesneriaceae is selected as being biodiverse on limestone, being well collected and outstanding in the number of endemic species and/or species restricted to limestone for mapping. Of the 210 species in the 25 genera of Gesneriaceae in Peninsular Malaysia, 42 species belonging to the genera Damrongia Kerr ex Craib, Emarhendia Kiew, A.Weber & B.L.Burtt, Epithema Blume, Microchirita (C.B.Clarke) Yin Z.Wang, Monophyllaea R.Br., Ornithoboea Parish ex C.B.Clarke, Paraboea (C.B.Clarke) Ridl., Senyumia Kiew, A.Weber & B.L.Burtt and Spelaeanthus Kiew, A.Weber & B.L.Burtt grow on limestone hills. Of these 42 species, 28 are endemic and 16 are restricted to a single or adjacent hills. Mapping their distribution shows that in common with other families there are three distinct phytogeographical provinces (the Northern Province, Perak Province and the Asian Intrusion) but that the narrowly endemic species do not cluster on particular hills, nor does their distribution coincide with those of other narrowly endemic species in other families. This illustrates that a network comprising a large number of hills, not only those within the three provinces but also all those harbouring narrowly endemic species that are at risk of extinction if not conserved, is necessary to maximise conservation of the biodiversity of the limestone flora.

Murum Dam in Sarawak is located about 70 km upstream of Bakun Dam, on the rivers Murum, Danum and Plieran, forming a reservoir over an area of 245 km2. The area consists of mainly lowland to hilly mixed dipterocarp forests, with riparian and alluvial forests along the main rivers and streams, as well as patches of mossy and heath forests. Most of these forests are logged over and some areas have been converted into oil palm plantations. A flora rescue project was carried out to collect selected plant species including orchids from the areas affected by the dam. Most epiphytic orchids were collected from partially submerged trees. Over 2,000 specimens of orchids from 80 genera and c. 276 species were collected from May 2013 to December 2014. The most abundant genus recorded is Bulbophyllum Thouars (c. 44 species). Of these, 37 species are endemic to Borneo, two (Bulbophyllum upupops J.J.Verm., P.O’Byrne & A.L.Lamb and Thrixspermum lingiae P.O’Byrne & Gokusing) are newly described and ten species are new records for Sarawak. The collection of species from this work has provided valuable material for the research and conservation of orchids from vulnerable areas around dams.

The taxonomy of plants provides a great contribution to understanding diversity and conservation. This study provides additional taxonomic notes on Podocarpus species in the Philippines using newly collected specimens to determine new distribution localities of these species. This study recognises ten species of Podocarpus in the Philippines. Notable results of this study are: (1) the existence of variable leaf forms in P. pilgeri Foxw. correlated to the type of habitat where the species occurs; (2) variable leaf forms and sizes observed in mature and juvenile leaves of all species; (3) support of the sectional arrangement of P. palawanensis de Laub. & Silba; (4) differences between the wild and cultivated representatives of P. costalis C.Presl based on leaf characters; (5) new distributions for P. ramosii R.R.Mill, P. pilgeri, P. costalis, P. neriifolius D.Don, P. rumphii Blume and P. polystachyus R.Br.; (5) no support for the inclusion of P. neglectus Blume and P. hookeri de Laub. as new species found in the Philippines; and (6) comprehensive examination and identification of numerous herbarium specimens and recently collected material.

Singapore has several public gardens of which two, Singapore Botanic Gardens and Gardens by the Bay, are of particular national and international renown. These two gardens have contrasting but complementary ways of enthusing and educating the public about plants and of gaining their support for horticultural excellence, botanical research and conservation. Founded in 1859, Singapore Botanic Gardens is an old and established garden with a long history of horticultural and botanical research, plant exploration and conservation. It became a UNESCO World Heritage Site in July 2015, the world’s first tropical botanic garden to receive this accolade. Gardens by the Bay opened in 2012 and its focus is on large-scale displays in spectacular settings, thereby attracting huge numbers of visitors since its opening. In their contrasting ways, both gardens enthuse and educate the public about plants and the natural world. This work lays the foundations for public advocacy of conservation efforts in Singapore, resulting in a very high level of public support for greening efforts and the protection of natural areas in land-scarce Singapore.
