Hanguana neglecta (Hanguanaceae): a new plant species from a heavily collected and visited reserve in Singapore

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.
