Non-existent categories
Before adding a category to an article, as you did to Miscanthus sacchariflorus, please make sure that the category page actually exists. In some cases, it may be appropriate to create a new category in accordance with Wikipedia's categorization guidelines, but it is usually better to use the most specific available existing category. It is never appropriate to leave a page categorised in a non-existent category, i.e. one whose link displays in red. You may find it helpful to use the gadget HotCat, which tests whether a category exists before saving a change. Thank you. -- Brown HairedGirl (talk) • (contribs) 01:01, 8 March 2019 (UTC)
