We need a better example than Faba, which is now deprecated and refers to Vicia. ENeville ( talk) 01:04, 20 November 2010 (UTC) reply

There are several plant families whose names don't match their type genera's:

• Fabaceae: as mentioned above, the type genus is Vicia.
• Theaceae: Camellia
• Onagraceae: Oenothera
• Cactaceae: the genus Cactus was split in three, none of which is currently called Cactus
• Caprifoliaceae: Lonicera; named for the species L. caprifolium
• Aquifoliaceae: Ilex; named for I. aquifolium.

I also know of an example among animals:

• Elapidae: originally named for Elaps, but that was moved to another family and renamed Homoroselaps. phma ( talk) 01:01, 28 September 2015 (UTC) reply
