The unique plant communities of the freshwater swamp forests of southern Johor (Malaysia) and Singapore attracted the attention of E.J.H. Corner, but there have been no comprehensive follow-up studies to his seminal work. Meanwhile, freshwater swamp forests in the region have been mostly lost to logging and in-filling for plantations or urban development. The Nee Soon catchment contains the last substantial tract of this forest type in Singapore. We collated the rediscoveries of vascular plant species presumed Nationally Extinct in the 2 nd and latest edition of the Singapore Red Data Book, and new records for the Singapore vascular plant flora from the Nee Soon catchment, including those that we found and collected through the establishment and survey of 40 vegetation plots, each 20 × 20 m. We have identified 672 species from 117 families, of which 288 are trees from 60 families represented by at least one stem ≥ 5 cm DBH. The catchment is especially species rich and abundant in the Myristicaceae. In the last ten years, 53 rediscoveries, 11 new species records, and two new varietal records have been uncovered from (or can be found in) the Nee Soon catchment. The Nee Soon freshwater swamp forest is one of Singapore's most valuable botanical areas, and warrants sustained conservation effort and study.

An illustrated revision of Marantaceae in Singapore with an identification key and proposed national IUCN Red List assessments is presented here. In total three genera and four species are considered native to Singapore (Donax canniformis, Phrynium hirtum, Stachyphrynium parvum, and Stachyphrynium latifolium) representing 33 % of diversity currently known to occur in Peninsular Malaysia. Although the genus Phrynium Willdenow (1797: 1) was previously reported for Singapore based on the presence of P. villosulum, we show that this species is, contrary to previous accounts, not native but introduced. Newly reported Phrynium hirtum therefore represents a new native generic record for the country. We are changing the status of Schumannianthus benthamianus, previously considered native, to cultivated, as there are no historic or recent collections of this species. Non-native species commonly employed in Singapore streetscapes and parks are also briefly discussed and illustrated in this paper. Actoplanes ridleyi, Donax grandis, Donax parviflora, Maranta tonchat, Phrynium latifolium and Phrynium sumatranum are lectotypified and Maranta arundinacea Blanco (non L.) is neotypified.

ABSTRACT. Hanguana podzolicola (Hanguanaceae) is newly recorded for Singapore. Detailed colour plates are given alongside the main characters for distinguishing this species from the two most similar species in Singapore, Hanguana rubinea and H. triangulata. The seeds of Hanguana podzolicola are described for the first time. A local conservation assessment is given. As no original material of Hanguana podzolicola could be traced, a neotype is designated here. Following a recent clarification of several historical Hanguana names it is noted here that the correct name for the large helophytic stoloniferous species often cultivated in Singapore under the name Hanguana malayana is Hanguana anthelminthica. An updated key to Hanguana species in Singapore is provided.
