Horticultural aspects

Hardiness It was flowering in the middle of winter in Brazil. It might be at least somewhat cool-tolerant. Bahia state is in the tropical part of Brazil, however, and therefore quite a bit warmer than the more southern states. Salvador, the capital of Bahia, is at latitude 13* south, approximately. By comparison, the country of El Salvador is at about 13-14* north, which is well south of the United States, even Hawaii.


Taxonomic group Its closest relative is S. barbata. That would place this species in the Corytholoma clade.
Location Serra do Orobó in Bahia state of Brazil.
