Freycinetia javanica Blume, previously thought to be extinct in Singapore, was rediscovered in Nee Soon Swamp Forest. It is newly assigned the national conservation status of ?Critically Endangered? as it is currently only known from two localities in the Republic.

This appears to be the second record and rediscovery of Calamaria gimletti from Singapore. The species was first reported for Singapore by Leong (2004 as Calamaria lowi gimletti) from a 226 mm (total length) specimen found preserved in the collections of the Lee Kong Chian Natural History Museum at the National University of Singapore. It was collected 70 years before on Pulau Pawai in November 1933. The species is listed by Baker & Lim (2012: 169) as having indeterminate status in Singapore. Calamaria gimletti can be distinguished from its congeners in Singapore by having 4 upper labial scales, no preocular scale, very slender body, a rounded tail tip; and being uniformly brown above, yellow beneath, with yellow spots irregularly placed along the sides of its body and tail (Tweedie, 1983: 54, 57 as Calamaria lowi gimletti). The species is known from Peninsular Malaysia and the Riau Islands off Sumatra (Das, 2010: 266).

Lindsaea divergens Hook. & Grev. (Lindsaeaceae) was reported to be presumed nationally extinct in Singapore, having no sighting and collection since 1892. A small population of the fern was rediscovered at MacRitchie Reservoir Park, Central Catchment Nature Reserve in 2009 and which is still extant today.

The lesser sheath-tailed bat was last recorded in Singapore at the Bukit Timah Nature Reserve by Shirley Pottie (1996). No records have been obtained since 1996 until the present discovery. This species is known to roost under boulders, and under fallen trees and buttresses. (Kingston et al., 2006). The present example was found roosting on the inclined corrugated ceiling of the structure which provides the roosting surface that lesser sheath-tailed bats seem to prefer (Fig 2). In Singapore, this species is listed as ‘critically endangered’ (Lim et al., 2008). Emballonura monticola has been collected from Pulau Ubin in the last century. Three specimens (ZRC 4.6368-6370) obtained there by F. N. Chasen on 31 August 1921 are in the Zoological Reference Collection of the Lee Kong Chian Natural History Museum at the National University of Singapore (Kelvin K. P. Lim, personal communication). The present record constitutes a rediscovery of this species for the island.
