@Peter coxhead: I started changing several of the former Maxillarieae genera to Category:Cymbidieae genera and I added a new category, Category:Maxillariinae genera (with the parent being Cymbidieae genera) for good measure, but I realized that the guidelines say that Cymbidieae genera shouldn't have subcategories (at least I think that's what they say). Should I get rid of category Maxillariinae genera? JadeSpire (talk) 02:21, 10 September 2020 (UTC)[reply]
@JadeSpire:Category:Cymbidieae genera can broken down ("diffused") into subcategories if it will be "too large" (what this means seems to be a matter of opinion, but 132 is definitely large) and if the subcategories will be "sufficiently large" (again a matter of opinion; at least 10 but preferably at least 20 seems to be acceptable). Two points:
If you do think that subcategories of an "X genera" category will be ok, then you need to edit the category page to change subcats=no to subcats=yes in {{Plant taxa category}}.
