Copiapoa lauii FK 439 Esmeralda Guanillos, Chile
It is the smallest of the Copiapoa's and a very attractive
clustering variety with lots of small heads when mature. It is easily
identified just by its small size, brown soft stems, minute spines,
large yellow flower and large tuberous root. It is the only
Copiapoa where the side branches form their own roots.
