Species imperfectly known D. bartschii Schulz (Not. Bot. Gart. Berl. 11: 391, 1930-34) was described from Erdschias (Ercias Da.), 1700 m, based on a gathering by Bartsch (204). It was related to D. sophia var. dasycarpa Schulz, from which it differed in the presence of small glandular hairs in the region of the inflorescence. The specimen, once in the Berlin herbarium, has been destroyed.
