TL;DR: Investigation of gene flow in the insect-pollinated, wind-dispersed tropical tree Koompassia malaccensis in and among three remnant forest patches in the urbanized landscape of Singapore found insect-mediated gene flow persisted across an urban landscape, and several of the results also parallel key findings from insect- pollinated canopy trees sampled in mixed agricultural–forest landscapes.

TL;DR: A new species of Hanguana neglecta is described and illustrated from the Bukit Timah Nature Reserve in Singapore, one of the most heavily collected and frequently visited forests in the world.

TL;DR: Ginger diversity remains high, but the number of species at immediate risk of extinction outnumber recorded extinctions, and slow relaxation of extinction debt should be explicitly identified as a conservation challenge and opportunity.

TL;DR: Support for synonymy of Anatropanthus with Hoya is strong and the new name H. insularis is proposed and a clade of three new species with Oreosparte-like morphology is sister to the rest of the Hoya group and is described as the new genus Papuahoya.

TL;DR: This diploid species is strongly clonal with only 13 genetically distinct individuals, which is surprising for a small, superficially delicate herb, and the best conservation interventions are discussed, but more information is needed on the factors that limit reproduction.
