Copiapoa pepiniana var. fiedleriana

Coming soon

 Copiapoa pepiniana v. fiedleriana North Huasco. Atacama, Chile. 
 

What is this plant?

Copiapoa pepiniana is a doubtfull species sometime regarded as a synonymy of C. coquimbana.
It is indeed hard to know what C. pepiniana should be referred to since nobody really knows what it is. This plant epithet is in fact a “Nomen dubium” that is a “Doubtfull name”. Identifying these old names is difficult because often the types were not preserved therefore later collectors and growers have stuck the name on different and often unrelated plants. C. pepiniana var fiedleriana should be the same as C. fiedleriana, a strongly spined plant which you could describe as intermediate between C. coquimbana and C. echinata.
