Abstract
Lilium brunneum represents a newly discovered and described lily species with a limited distribution in isolated alpine regions of north-western Yunnan, China. The recognition of this new species as a distinct entity is supported by both morphological and molecular data. Furthermore, the investigation of this region, identified as a ‘hotspot’ due to its high diversity and endemicity within the genus Lilium, is anticipated to provide greater insight into the processes of speciation and the maintenance of species boundaries in this genus. Further fieldwork aimed at exploring these regions is expected to discover additional new species and therefore warrants special attention and resources.

Chinese name: 焦瓣百合 (jiao ban bai he)
Diagnosis. Lilium brunneum shares morphological similarities with L. georgei, L. souliei, and L. saccatum but exhibits distinct differences that set it apart. Compared to L. georgei, L. brunneum is characterised by its shorter stature and smaller flowers. In contrast to L. souliei, it possesses shorter pedicels, and its filaments are closely appressed to the ovary. When compared to L. saccatum, L. brunneum is distinguished by its unique petal coloration, which ranges from brown to light brown with a greenish-yellow base. (Table 1, Fig. 2).

Habitat and distribution. On open stony alpine meadows and edges of bushes. 3500–3800 m. NW Yunnan (Fugong[福贡]) and bordering Myanmar (Kachin).
Etymology. The epithet and Chinese name adopted here both denote the perianth colour of light brown resembling that of caramel.
