Paeonia kesrouanensis(1)

Perennials. Roots carrot—shaped. Stems 35—80 em tall, glabrous, green, sometimes with purple spots or partially purple at the base, with 4-7 yellow—green scales at the base. Petioles and petiolules glabrous. Lower leaves biternate; leaflets/leaf segments 10—14, rarely up to 17 in number, ovate or elliptic, acute at the apex, 8—l8 cm long, 4—7.5 cm wide, glabrous above, sparsely to rather densely villose beneath. Flowers solitary; involucrate bracts mostly one, rarely 2 in number, leaf-like, or absent; sepals 3-4, less frequently 2 or 5 in number, nearly orbicular, mostly or all rounded but sometimes one acute at the apex, green but often purple at the periphery, usually glabrous, rarely sparsely hirsute outside; petals 5—9 in number, pale pink, pink or red, 4.5-6.3 cm long, 2.5-4.2 cm wide, mostly entire, rarely incised; filaments dark purple; anthers yellow; disk 1 mm high, entire, rarely waved; carpels 1—3, rarely 4 or 5 in number, glabrous; styles 1.5—3.5 mm long, styles and straight part of stigmas together 3.5-7.0 mm long.

Chromosome number: 2n = 20 (tetraploid)

Growing in Fagus orientalis, Pinus nigra or Cedrus libani forests or in Quercus scrubs in areas of limestones or metamorphic rocks at altitudes from 1,000 to 1,800 m. Confined to Lebanon, SW Syria, and SW and S Turkey

Paeonia kesrouanensis is a distinct species. It grows together with P. daurica in Mt Amanos in S Turkey, but we found no hybrids there. It differs from P. daurica not only in morphology (lower leaves with 10-17 leaflets/leaf segments; carpels 1-3, always glabrous in P. kesrouanensis) but also in ploidy (2n = 20 for P. kesrouanensis versus 2n = 10 for P. daurica). Paeonia kesrouanensis also grows together with P. mascula on Ziyaret Hill, above Senkoy, Antakya, Turkey, where we did not find hybrids. The population of P. mascula there, like the populations elsewhere, had carpels that were 3-5 in number and lanate, and sessile stigmas, and was thus distinct from P. kesrouanensis. Paeonia kesrouanensis is similar to two other allopatric species, P. coriacea (S Spain and Morocco)‘and P. cambessedesii (the Baleares, Spain). However, P. coriacea is nearly always glabrous throughout, and P. cambessedessi is always glabrous throughout, with its lower leaves nearly always of 9 entire leaflets and mostly (3—)4—6(—8) carpels.
Paeonia turcica was described as new by Davis and Cullen due to its having styles and stigma that are shorter than those in P. kesrouanensis and curved near the base (rather than curved only at the apex in P. kesrouanensis). The length of style and stigma in P. turcica is, however, in the variation range of those in P. kesrouanensis (4.5—7 mm) and they curve at various positions. Therefore, P. turcica was treated as a synonym of P. kesrouanensis.

I’ve been waiting for this stunning picotee peony to flower for years. It got close last year, but a bowerbird stole its two flower buds. This is the first of eight flowers to open this year. Bought as Paeonia kesrouanensis, the Syrian Peony. However looking at both the Hong and ...

Rather weird, I would say: Paeonia kesrouanensis again. The flower corresponds to the description in Hong's book, but I did not expect it to flower already as the leaflets haven't unfolded as yet. Great and strong fragrance. Style/stigma well curved as can be seen in the last picture. #paeoniakesrouanensis #paeonia ...

Some species peonies have started growing in the greenhouse. The most remarkable one being Paeonia kesrouanensis, showing its petal colors before the foliage. Next is Paeonia corsica (or Paeonia morisii if you like to 'split' species). Last one Paeonia clusii, showing wider leaflets than as a young seedling. #paeonia #paeoniakesrouanensis ...

It was the right decision to move our Syrian Peony, Paeonia kesrouanensis, as I posted on 25 March. Free from the competitive roots of a large Japanese maple, it has now developed many leaves and two flower buds. Our earliest peony by far #paeoniakesrouanensis #syrianpeony #paeonia #peony #speciespeony #blackheathnsw #bluemountainsgardens ...

This Syrian peony, Paeonia kesrouanensis, has spent the last five years in the wrong spot in the garden. In that time it hasn’t flowered and it has never had more than two leaves. The spot was too shady and the poor plant had to compete with too many roots from ...
