There are many species of stenogyne. S. calaminthoides is by far the most common, and is even relatively common in very disturbed habitats. I find s. sessilis occasionally on the saddle. The rarer s. macanthra and s. scrophularioides are difficult to find in windward wet forests. The dry upper saddle and upper mountainsides are inhabited by species microphylla, angustifolia and rugosa, which all look quite distinct. Kohala was host to two species, endangered cranwelliae and extinct oxygona.
