Definition
Kerria yunnanensis is a purported species of flowering plant within the genus Kerria (family Rosaceae). Precise taxonomic status, distribution, and morphological details are not well documented in widely available encyclopedic sources.
Overview
The genus Kerria comprises deciduous shrubs native to Asia, best known for the ornamental species Kerria japonica. References to Kerria yunnanensis appear sporadically in specialized botanical literature, suggesting it may be a regional taxon associated with the Yunnan province of China. However, comprehensive treatment of the species in major floras or databases (e.g., The Plant List, Tropicos, IPNI) is lacking, and it is unclear whether the name is currently accepted, synonymized, or regarded as a nomen nudum.
Etymology / Origin
The specific epithet yunnanensis is a Latinized adjective meaning “of Yunnan,” referring to the Yunnan province in southwestern China. This naming convention is common for plant species first collected or described from that geographic region.
Characteristics
Accurate morphological or ecological characteristics for Kerria yunnanensis are not confirmed. If the name corresponds to a valid species, it would likely share general traits of the genus, such as:
- Shrub habit, typically 1–3 m tall.
- Simple, alternate leaves with serrated margins.
- Yellow, five‑petaled flowers arranged in panicles or clusters.
Without verified descriptions, these attributes remain speculative.

Note: The paucity of reliable, peer‑reviewed information on Kerria yunnanensis precludes a detailed encyclopedic entry. Further research in specialized taxonomic monographs or herbarium records would be required to confirm its existence and attributes.
