Thursday 3 March 2016 – Bahia de Los Angeles to Santa Rosalia
It was a long drive and not quite what was planned.
We should have looked for accommodation as we entered Baja California Sur, in Guerrero Negro, .but it was still early and I thought that we would gain an hour by crossing the State border.
In any event, after five previous trips I finally spotted four plant of Mammillaria dioica with very distinct flowers to say that they were not. My guess is M. blossfeldiana judging by images on page 90 of John Pilbeam’s 2015 ‘Cacti & succulents of Baja California’ book.
