Dyckia catharinensis is one of the very first Dyckias to be described and also one of the first to have its scientific name turned invalid as it was said to be a Dyckia encholirioides.
But it does exist and it is quite different from encholirioides.
Thy both live in a very similar habitat but they do not share it.
Catharinensis lives on the southern half of Santa Catarina Island and from there up to Garopaba.
The northern half of Santa Catarina Island is inhabited by encholirioides
