B. hamatum grows in Wufeng County, Hubei, China, on damp moss rocks and trees in the subtropical evergreen broad-leaved forest at the elevation 950 – 1200 m. Three subpopulations were found around the type locality. Taxonomic note: B. hamatum mainly differs from B. omerandrum in hooked or falcate stelidia. The morphological differences between them were summarized in Table 1 and Fig. 2.	en	Yan, Qi, Li, Xin-Wei, Wu, Jin-Qing (2021): Bulbophyllum hamatum (Orchidaceae), a new species from Hubei, central China.
