Paeonia officinalis L. var. simplicifolia
See Paeonia officinalis L. for a description of the species.  Paeonia paradoxa var. simplicifolia is described in Paxton’s Magazine of Botany as ‘a flower of eight petals, of little interest.’  [MB p.138/1836].  

History at Camden Park
Listed only in the 1850 catalogue.

Notes
Both Paxton’s and Johnson’s Dictionary list Paeonia simpliciflora, a red-flowered species from the Levant.  It is probably a different plant.
