Description
Petrocodon dahuaensis, a new species from a limestone area of Guangxi, China, is described and illustrated. The new species is similar to P. asterostriatus but differs in its leaf blade, cordate to subrounded, margin crenate to serrate; bracts, bracteoles, and calyx smaller; corolla purple, base straight to slightly inflated; filaments purple; and style densely glandular-puberulent. Molecular evidence also supports its close relationship with P. asterostriatus. According to the IUCN Red List Categories and Criteria, the provisional conservation status of P. dahuaensis is assessed as Data Deficient (DD).
