Wings sprouted from each wither - vast, black leathery wings that looked as though they ought to belong to giant bats.

I think wither is used as a noun word. But I can't find it's a noun in dictionaries. The only one I get is "withers" means "the highest part of a horse’s back, above its shoulders". Does this use of wither mean the same as withers?
