^aData for MSB collections were extracted from the MSB's Seed Bank Database on 5th February 2018, comprising angiosperm native and archeophyte taxa collected in the UK, including sub-specific taxa and microspecies.

^bMSB data were cross-reference with the UK's angiosperm native and archeophyte flora using data from the Botanical Society of Britain and Ireland (BSBI, 2007) incorporating changes identified in Stace (2010) and additional data from McCosh and Rich (2011).

^cThreatened taxa identified using IUCN Red List categories EX-VU (JNNC, 2018).
