Neolitsea levinei var. tibetica H. P. Tsui (Acta Bot. Yunnan. 16: 35. 1994) was described from SE Xizang (Mêdog) but could not be treated here because no material was seen by the present authors. Judging from the description in the protologue, it almost certainly belongs in Cinnamomum, rather than in Neolitsea, and is perhaps a synonym of C. iners (species no. 41).
The roots are used medicinally.
