Abstract
Acronema handeloides, a new species of Apiaceae from Jiaozi Mountain in Yunnan Province, is described and illustrated herein. This species is similar to A. handelii and A. sichuanense but can be distinguished by its 1-2 branches; variable basal leaves; bracts 1 or occasionally present, bracteoles 1-3; subulate calyx teeth; linear-subulate, papillate petal apex; and broadly ovoid. Phylogenetic analyses also support that it is a monophyletic group sister to A. handelii and A. sichuanense. In accordance with the IUCN Red List criteria (2024), the conservation status of A. handeloides is preliminarily assessed as Data Deficient (DD).
