Context 1
... the natural forested area, an abundance of Tristaniopsis species (Myrtaceae) was found around the area marked as point 25 on the vegetation map (Fig. 3). As individuals could not be identified to species in the field, it was estimated that there are more than 20 mature individuals from the genus Tristaniopsis (Fig. 4A). Subsequent examination of the voucher specimens revealed that the Critically Endangered Tristaniopsis obovata and Endangered Tristaniopsis whiteana (Myrtaceae) are most likely the species that are highly abundant in the forest. Further north on a vertical cliff located within the coastal forest is a mature Fagraea auriculata tree, ...

... (Myrtaceae) are most likely the species that are highly abundant in the forest. Further north on a vertical cliff located within the coastal forest is a mature Fagraea auriculata tree, marked as point 6 on the vegetation map (Fig. 3). This is also a critically endangered species and several saplings were seen growing on the face of the cliff (Fig. 4B) and across the ...

... species on the island, and as some of them have relatively large wild populations, attention should be paid to ensure the persistence of the native genetic stock. For example, several saplings of Fagraea auriculata, a Critically Endangered species, were found growing on a vertical cliff within the natural coastal forest of Pulau Tekukor (Fig. 4B), and this species may be propagated readily by air-layering. From our experience, it can also be easily propagated using root cuttings. Results from a study by Yeo et al. (2011) that examined the effectiveness of air-layering for the mass propagation of Fagraea auriculata revealed a high successful rooting rate, where 94.2% of the ...

This paper is the eighth instalment of the continuing series on the tree species of the floristically diverse Nee Soon Swamp Forest, Singapore's last substantial tract of intact freshwater swamp forest. Here, we provide a key and species descriptions based on characters observable in the field and from dried specimens for the 14 species of the five genera of the family Sapotaceae found there. These five genera are: Madhuca (three species), Palaquium (six species), Payena (one species), Planchonella (three species) and Sarcosperma (one species). Of these, Sarcosperma paniculatum is a recent rediscovery in Singapore, and together with Palaquium microphyllum and Planchonella maingayi, represents a new record for the flora of the Nee Soon Swamp Forest. Madhuca tomentosa is a misapplied name and is determined to be another Madhuca species (here called Madhuca sp. 1), the identification or formal description of which await the collection of fertile specimens.
