Dendrocalamus wazibii (Poaceae, Bambusoideae), a new bamboo species from Yunnan, China

Dendrocalamus wazibii (Bambusoideae), a new bamboo species is described and illustrated from Cangyuan County, Yunnan, China. Based on careful comparison of morphological and generative characters, we confirmed its identity as a new member of the genus Dendrocalamus. The morphology of this new species is similar to D. peculiaris and D. tomentosus, but can be easily distinguished from them by having culm leaf ligule 15 mm long (vs. 5–7 mm in D. tomentosus and 6–10 mm in D. peculiaris), linear culm leaf auricle (vs. absent in D. tomentosus and D. peculiaris), anther 2–2.5 mm long (vs. 2.5–3 mm in D. tomentosus; vs. 3–3.5 mm in D. peculiaris), stamen 5 mm long (vs. 6 mm in D. tomentosus; vs. 10 mm in D. peculiaris).

According to the IUCN Red List Categories and Criteria (IUCN 2024), it meets the criteria to be listed as Data Deficient (DD).
