Abstract

During 2015, two drift endocarps of Pangium edule were found stranded in southern British waters, the first from Dungeness, Kent (25/09/2015) and the second from Loe Bay Beach, Cornwall (13/11/2015). The specimens represent the first records of P. edule drift endocarps from British waters. Four specimens have previously been recorded from Dutch (3) and Danish (1) waters. A first record of P. edule from Bermuda (NW Atlantic) in mid-December 2015 is also reported.

Highlights

  • Pangium edule Reinwardt (Achariaceae) is considered to be a monotypic species but its taxonomic position is currently uncertain (Chase et al, 2002; Rana & Ranade, 2009; Wurdack & Davis, 2009)

  • P. edule is native to Malesia (Indonesia, Malaysia, Philippines), Melanesia (Papua New Guinea, Fiji), and Micronesia (Hemsley, 1885; Merrill, 1918; Bourke, 1996; Walter & Sam, 1996; Costion & Lorence, 2012)

  • Nelson (2000) and Thiel & Gutow (2005) stated that P. edule seeds are capable of floating for at least 19 years, whereas Perry & Dennis (2010) remarked that they can float for 30 years

Summary

Introduction

Pangium edule Reinwardt (Achariaceae) is considered to be a monotypic species but its taxonomic position is currently uncertain (Chase et al, 2002; Rana & Ranade, 2009; Wurdack & Davis, 2009). Drift endocarps of P. edule have been recorded from a wide geographical area within the Indo-Asian-Pacific region, including the Cocos-Keeling Islands (Guppy, 1890) and Christmas Island (Ridley, 1930; Green, 1999) [eastern Indian Ocean], Australia (Kenneally, 1972; Hacker, 1990; Smith, 1994, 1999; Smith et al, 1990; Pike & Leach, 1997), Malaysia (Ridley, 1930), Java (Ridley, 1930), Taiwan (Anon, 2016), and Japan (Longhorn, 2004; Nakanishi, 2011).
