How to rename to hybrid

[bouteloua]

Or by getting one of the staff to update it.

• Allow more users to edit taxon names to reduce “pointless” taxon changes for things like typing/spelling mistakes, e.g. epithet ending in “-a” vs. “-us” or hybrid symbol “x” → “×”

Kew’s Plants of the World Online adds the space after the hybrid symbol. Space or no space is optional, at least in the plant code, and it’d be nice to be consistent, so I’ve been keeping the space.
