Since the publication of Lithops gulielmi L. Bol. in 1937, with type locality given as "farm Florida", there has been considerable doubt and uncertainty about this taxon. Descriptions and illustrations appearing in subsequent publications differ substantially from the original diagnosis, and plants collected at the type locality did not conform to any of the pubIished descriptionptions.
