All the records from James Aronson's original list in HALOPH (Aronson 1989) together with those in the lists compiled by Menzel and Lieth (2003), Khan and Qaiser (2006) and Zhao et al (2002; thanks to Prof Hugh Pritchard for converting the published list to an Excel spreadsheet) have now been evaluated for inclusion in eHALOPH. In revising the list of salt-tolerant plants, we (Moh'd Al-Azzawi and Tim Flowers) comprehensively reviewed more than 2500 species. We have added nearly 300 species, but not added or deleted nearly 1300 species, as we have been rigorous in requiring published evidence for salt tolerance before including a species in eHALOPH. Additionally, Moh'd and I have reviewed (July 2022) the Economic uses of all the species in the current database.

A list of plants that might be salt tolerant can be obtained from t.j.flowers@sussex.ac.uk.

WE HAVE RECENTLY (July 2025) COMPLETED revising the data in the field 'Maximum Salinity tested/tolerated' and populating the Optimal salinity and Ionomics fields .

New references on salt-tolerant plants discovered by searching the Web of Science for the term 'Halophy*' are added each month.

Initially (from 2014 to 2018) we used 'The Plant List' [http://www.theplantlist.org/] to check species nomenclature and some cases names of species were 'unresolved'; where this was the case this may be noted in the 'Miscellaneous notes', a part of each record in eHALOPH. From November 2018 names have been checked against Plants of the World Online [http://www.plantsoftheworldonline.org/].

We have not systematically added all synonyms and users of eHALOPH should check' Plants of the World Online' or 'The International Plants Names Index' (IPNI)  if concerned about the taxonomy of a halophyte that does not appear in eHALOPH.

Version 5 of eHALOPH incorporates some ' Help' screens as well as updates to software packages and various administrative functions. Further Help text is still to be added. There is also an eHALOPH API made available through funds from the COST Action SUSTAIN.
