The Tree Pæony. 
...The above varieties, viz., Banksi, rosea, and papaveracea, are all that are described in Anderson's "Monograph of the Genus Pæonia", given in vol. vi. of the Horticultural Society's Transactions (1838), but in Loudon's "Arboretum Britannicum" (1854) a dozen are described, all bearing Latin names.  There are, besides the three just named, Humei, double blush; variegata, white streaked with violet and purple; rosea semi-plena, rosea plena, Rawesi, single pale pink; carnea plena, double flesh coloured; albida plena, double white, flushed with mauve; Anneslei, small single purplish pink; and lacera with the petals curiously cut into strips.  These nine varieties had probably all been raised from seed obtained from Banksi, rosea, and papaveracea, for at that time the Earl of Mountmorris, at Arley, and the Earl of Sandwich, at Hinchingbrooke, both took a great interest in the Tree Pæony, and raised several distinct sorts chiefly from the single papaveracea.

12. P. Moutan lácera Lindl.  The cut-petaled Moutan Peony. — This very beautiful variety is strikingly different from the others in the bright rosy red of the petals, the innermost of which are very much cut and gashed, curled up, and distinctly bordered with a narrow edge of light carmine, which sets them off to great advantage, and gives the whole flower a peculiarly rich and finished appearance.  Raised in 1831, from seed, by Mr. William Hyland, gardener to the Earl of Sandwich, at Hinchingbrook, near Huntingdon.

Paeonia Moutan; lacera. Double-red curled Tree Paeony...
Garden Variety. Raised from the seed of Pseonia Moutan by Mr. William Hyland, Gardener to the Earl of Sandwich, at Hinchingbrook, near Huntingdon, and communicated to us by Michael Foster, Esq.
This very beautiful variety is strikingly different from the other Moutans in the bright rosy red of the petals, the innermost of which are very much cut and gashed, curled up, and distinctly bordered with a narrow edge of light carmine, which sets them off to great advantage, and gives the whole flower a peculiarly rich and finished appearance. Mr. Hyland informs us that the seed was sown in September, and did not germinate for eighteen months afterwards; and that he finds such to be the case with all the seeds he has sown of this kind of Paeony.
It flowered for the first time in April 1834, when the plant was only three years old. It may therefore be expected that the future blossoms will be still finer than what we have figured.
