Rediscovery of the Sculptured Toadstool, Amanita sculpta (Amanitaceae) in SingaporeFlora of Singapore precursors, 25: Taxonomic notes on new discoveries from Bukit Timah Nature Reserve, including two native genera newly recorded

Abstract

As part of a project to sample tissue from all native vascular plants in Bukit Timah Nature Reserve, we collected material from four species that have not been previously recorded in Singapore. Of these, Nervilia singaporensis Niissalo has already been described as a new species, native to Singapore. Two species, Lepidogyne longifolia (Blume) Blume (Orchidaceae) and Ptyssiglottis kunthiana (Wall. ex Nees) B.Hansen (Acanthaceae), which are reported here, belong to genera that have not previously been recorded in Singapore. Based on their collection history in the region and their habitat in Bukit Timah Nature Reserve, we consider them native to Singapore. The fourth new record, Plectocomiopsis cf. corneri Furtado (Arecaceae), also reported here, is a new species record for Singapore, but based on the collection history of the species and its only known locality in Singapore, we consider it introduced. The nomenclature and history of these species are discussed and we designate lectotypes for several names that are relevant to these species: Neottia longifolia Blume, Lepidogyne sceptrum Schltr., Polytrema aequale Ridl., Polytrema aequale Ridl. var. minor Ridl. and Polytrema vulgare C.B.Clarke. We also designate a neotype for Lepidogyne minor Schltr.
