Kingdonia uniflora is a species of perennial herb native to China.

[1] It grows at high elevations in West and North China.

Analysis of its draft genome hinted that its restricted distribution and endangered status relates to the loss of specific gene families.

[2] Kingdonia is sometimes classified as the only genus in the family Kingdoniaceae[3] or as a member of the family Circaeasteraceae along with Circaeaster agrestis, specifically in the APG III system of classification.

[4][5] Other sources may classify Kingdonia in the buttercup family, Ranunculaceae.
