S. iarae is a species that has been introduced to cultivation relatively recently, in large part because of the efforts of Mauro Peixoto of São Paulo, Brazil.
The flower has the overhanging upper lip (“galea”) characteristic of related species, such as S. cardinalis and S. hatschbachii. In S. iarae, this galea is often reflexed (i.e. bent upward at the tip). The tuber of this species is usually exposed, in part above-ground. Many member of the genus grow in this manner, and these species often grow on rocky hillsides or cliffs.
