Discussion

Sphaeralcea procera is known only from the type collection, from Luna County. It is closely related to S. polychroma, which is usually common when it is found. It is surprising that S. procera is known only from a single collection. Botanists, including me, have looked for it around the type locality without success. It is retained here pending evidence that it is conspecific with S. polychroma or extinct.

"not wider" is not a number.
