8. Circaea ×dubia H. Hara, Bot. Mag. (Tokyo). 50: 306. 1936.

可疑露珠草 ke yi lu zhu cao

This is the hybrid Circaea cordata × C. erubescens and is intermediate between the parents. The flowers have the exserted nectary of C. erubescens and usually at least a few of the long, spreading hairs of C. cordata. They also resemble C. cordata in being more robust, in leaf shape and in having more closely spaced flowers at anthesis. Although the petals are more like those of C. cordata in shape, they are often pink as in C. erubescens.

Disturbed areas, commonly along streams, in broad-leaved deciduous forests. Near sea level to 1500 m. NE China ("Manchuria, 1941" without further data) [Japan].
