TL;DR: 15 fruit morphologies are shown here to demonstrate significant phylogenetic signal and to provide clear synapomorphies for several infrageneric clades and suggest that they may be the result of adaptation to different frugivores (birds, larger non-volant animal and primate seed dispersers, respectively).

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.
Abstract: We describe and illustrate a new species, Hanguana neglecta (Commelinales, Hanguanaceae), from the Bukit Timah Nature Reserve in Singapore, one of the most heavily collected and frequently visited forests in the world. The species, growing prominently near the path at the nature reserve, was not described despite being identified as new fifteen years ago, owing to long-standing taxonomic misconceptions in Hanguana. The key to Hanguana in Peninsular Malaysia is here updated.

TL;DR: An overview of its phytochemical and pharmacological properties is enumerated, which may provide assistance to researchers to determine further, the efficacy and potency of C. excavata as medicinal plant.
Abstract: The present review describes the morphological, traditional, phytochemical and pharmacological aspects of Clausena excavata ( Burm. f., Rutaceae). The plant grows wild in the tropical and subtropical parts of Asia and represents one of the richest sources of medicinal natural products. It is intensively used currently in traditional medicine for treatment of different illnesses. One part or a mixture of two or more parts of the plant in the form of powder or liquid doze is usually given to the patient. Phytochemically, many pure compounds from several secondary metabolite groups of C. excavata have been isolated from different parts of the plant including leaves, stems, stem barks, roots, root barks, rhizomes and flowers. Their chemical structures however, have been elucidated using several spectroscopic techniques. Pharmacologically, many secondary metabolites including alkaloids and coumarins have been tested for their biological activities. Anticancer, immunomodulatory, anti-HIV-1, antioxidant, antibacterialial, insecticidal, antifungal, antinociceptive, anti-malarial and antiplatelet activities of this plant have been detailed here. This paper enumerates an overview of its phytochemical and pharmacological properties, which may provide assistance to researchers to determine further, the efficacy and potency of C. excavata as medicinal plant.
