PK Comments

The official naming of the species at the mouth of the Botija Valley was very welcome. Our impressions on visiting the habitat on two occasions in 2001 was of a plant that, in habitat, was unlike any that we had seen before (or afterwards).  However, I was very surprised to see plants raised in the UK from habitat seed – their appearance in cultivation is so different from the plants in habitat, that they may as well be different species – which, uncomfortably, brings us back to possible links withC. varispinata.

Copiapoathons: We saw Copiapoa ahremephiana at Caleta Botija and at the mouth of the Quebrada Botija, recorded at:
