北方露珠草 bei fang lu zhu cao

This is the hybrid Circaea canadensis subsp. quadrisulcata × C. cordata and is most obviously intermediate between the parents in degree and the nature of pubescence and in the morphology of the flower parts. It is similar to C. cordata in having sporadic, long, sharply pointed, straight or slightly curved spreading hairs on various parts of the plant and in having a pubescent stem. It is similar to C. canadensis subsp. quadrisulcata in the color of the buds, sepals, and petals and in the presence of a low, exserted nectary projecting beyond the opening of the floral tube. It also has the densely glandular inflorescence of C. canadensis subsp. quadrisulcata , but the closely spaced flowers and petal shape of C. cordata.

Disturbed habitats; near sea level (upper elevation unknown). Hebei, also "Manchuria, Korii-mon" [Japan].
