== Zante currant == 

 Help! I've been reading the article on Zante currant and have made a few edits.  About halfway through the article I came upon 'Black Currant' and 'Red Currant' and 'White Currant'.  Since the article seemed to be written primarily in American English, I decided to change the single quotation marks to double quotation marks.  (Single quotation marks are rarely used in American English; they are used only when enclosing a quote (or a quoted word or two) within another quote.)  I finished one section and then started the next, where I saw more of these phrases.  I also noticed phrases in double quotes in the same section.  I stopped changing them.  I started wondering whether putting something like this in single quotes was something special to botanical terms.  (I also wondered whether the quotes were necessary at all, after the first mention earlier in the article.) If you think the quotes should stay (and then I'd have to replace the ones I changed), is there a way to find out whether the single quotes are correct for these particular phrases?
