Hab. Common in Mexico. This is now the commonest species in
European gardens, next to S. Kraussiana. In Ann. Sc. Nat. series 4, vol. 13, p.
67, A. Braun fully defines its varieties. The most striking is divaricata, with
fewer and more divaricating branchlets than iu the type, and smaller and less
crowded leaves.
