Follow link for details on coverage:
General - search the whole record
The most powerful search, covering all the database fields.
Enter words to search for, without any punctuation characters except the wild card character (*).
Author(s) - search by the author name
The format in which names are stored in the database is : surname_initial(s) e.g. Brown_GE.
Punctuation marks are ignored or a space left. You can enter only a surname and all authors with that surname will be considered.
If you wish to search by both the surname and initials you should enter it either as: - Brown_GE or "Brown GE". If you don't know the full initials of the author you can use a wild card search such as Brown_G*.
Please note that if neither the underscore nor the quotations are not used, e.g. Brown GE, this will result in all records where the author is Brown, combined with all records where the author has the initials GE.
Title - search in the article title
Searches for specified words in the title of an article; this is useful to limit retrieval if a search word also forms part of a journal name. Example: cactus if searched in the whole record will retrieve all articles about cactus plus all articles from the journal Cactus.
Journal - search in journal title, book publisher or series
Restricts search to a particular journal title, book publisher or series statement. Journal titles are stored using standard abbreviations. To search for a journal enter the first part of a journal title word followed by a truncation symbol (*).
Search by keywords
If you enter a term(s) in this box the search will be limited to subject keywords. For most users, the General Search (which searches all terms in the database) will be more suitable. Each data set uses different keywording rules.
Kew Record is normally only indexed to genus level; species names are not added as keywords. Names of genera are as given by the authors of the articles. Up to 6 generic names may be added for each article. Commonly used keywords are genus names, family names, and geographical areas. For each genus, the family name (for Angiospermae) or class name (for Pteridophyta and Gymnospermae) is added. Family names used are those given in Vascular Plant Families and Genera Database. For other keywords used see the KR keyword popups (accessed via the advanced search page)
Economic Botany citations are best searched by genus name or country name, or a combination of the two. After 1995, citations are also keyworded according to the Economic Botany Data Standard. Truncated keywords (e.g. medic* for medicinal plants, poison* for poisonous plants) work best.
Plant Micromorphology normally indexes for both subject and family name keywords. Family names used mostly follow those in Vascular Plant Families and Genera Database, though older references will be indexed with different names and therefore it may be necessary to search under previously used names. Genera should be searched for in the general box. Species names are not added as keywords.

Language - search by Language or Summary Language
Main languages include En (English), Fr (French), Ge (German). Leave blank to accept any language.
Publication date - search by publication year or a range of years
Select the start year in the left box and the end year in the right box. To set a lower or upper limit, leave the right or left box empty. To limit a search to one year, enter it into the publication date box.
Added since - search for records added since a particular date
Restricts your search to records that were added since the date entered. This allows you to see only the most recent additions to the database, if you're looking for new material.
You need to use the following date format:
YYYYMMDD (Year Month Day)
For instance, the 23rd June 2007 would be entered as
Please note that there can be a delay between records being added and those records becoming visible on the site. This means that your search may miss some records if you set the date too tightly. If you suspect you may have misssed some records, try setting the 'date added' back further in the past by a week or two, to ensure you pick up everything.
