Solanum septemlobum var. indutum Handel-Mazzetti (Oesterr. Bot. Z. 83: 234. 1934) was distinguished by being densely covered overall with capitate glandular hairs of varying length, but this condition sometimes occurs in more or less typical material of S. septemlobum. Without seeing the type material, which was collected in S Shaanxi, the identity of this variety remains uncertain.
