original description

P. tenuifolia x triternata.

The other form is represented in the Saunders garden by four clones, all received as P. anomala, and several seedlings of known hybrid origin. Three of these clones were received from Barr & Sons, the first originally under the name P. anomala, but later changed (in litt.) to P. anomala intermedia, the second as P. anomala insignis. The fourth clone was purchased from a German firm as P. anomala.

x Paeonia Saundersii hybr. nov. (P. tenuifolia x triternata). Planta ca. 5 dm. alta; segmenta foliarum laeiniato-pinnatifida, supra glabris, subtus minute et sparse pubescentibus vel glabris; sepala 6-7, extimum foliacenm, integrum et linearo-lanceolatum vel pinnatifidum cum 3-5 lobis lanceolatis, intimum rotundatum, emucronatum; petala obovata; discum 1-1.7 mm. altum; follicula (cum stigmo) ad anthesin 14—19 mm. longa, erecta, dense tomentosa, ad maturitatem horizontaliter patentia, 25-30 mm. longa; stigma plus minusve recurvata.

Plant 5 dm. high; divisions of the leaves laciniate-pinnatifid, the lobes linear-lanceolate, 3-12 mm. broad, glabrous above, minutely and sparsely pubescent below or glabrous, acute or acuminate; sepals 6-7, the outermost entire and linear-lanceolate or pinnatifid with 3—5 lanceolate lobes, the innermost rotund, cup-shaped, emueronate, 6-7 nerved, 20-25 mm. long and 18-25 mm. broad; petals obovate, 3.5-5.5 mm. long, 2-5 mm. broad, red, pink, or yellowish pink; anthers 3-5 mm. long; disk 1-1.7 mm. high, somewhat undulate ; follicles (with stigma) at anthesis 14—19 mm. long, erect, densely tomen-tose, at maturity horizontally spreading, 25-30 mm. long; stigma more or less recurved.

The natural occurrence of this hybrid has been reported by Maleev (1937). In cultivation, forms apparently identical with those described by Maleev are distributed erroneously as P. anomala, and under the following names given to various clones by Barr & Sons: P. anomala "Peter Barr," and P. anomala "insignis." Later Barr & Sons (in litt.), following the advice of the late Dr. Otto Stapf, designated these forms with tomentose follicles as P. anomala intermedia.

From true P. anomala this hybrid differs conspicuously in its narrower, more numerous leaf segments; in its sepals, the innermost of which in P. anomala is much less conspicuously cup-shaped, and is either mucronate or with a conspicuous midrib; in the color of its flowers, which in P. Saundersii have the red of P. tenuifolia more or less evident, and lack the magenta sliades most characteristic of P. anomala; and in its follicles, which in P. Saundersii are larger both at anthesis and (notwithstanding their sterility) at maturity.

P. hybrida (P. intermedia) is much more like P. Saundersii, and superfi-cially they are very difficult to distinguish from each other. In P. hybrida, however, the leaves are more finely dissected than in P. Saundersii, and their pubescence is either absent or confined to the main veins, both above and below, and to the margins; in P. Saundersii pubescence is distributed evenly, though sparsely, over the undersurface. The former type of pubescence is characteristic of forms of P. anomala, the latter of P. triternata. The flowers of P. hybrida are smaller in all their parts, and the disk is absent or rudimentary, the follicles are less spreading at maturity (in both the sterile garden hybrid and the ferthe wild form), and the stigma is less strongly recurved.

This hybrid has been produced in three different ways by Dr. Saunders, and several plants of it of known origin are in existence. The first two series are reciprocal hybrids between P. tenuifolia and the yellow-flowered form of P. triternata, P. Mlokosewitschii (for a discussion of this species, see below). They are identical with the forms distributed as P. anomala, except that their flowers are not red, but salmon pink or somewhat yellowish. The third group, which has only recently come into bloom, has as its parents the same clone of P. tenuifolia as the other two, and a plant of typical P. triternata received (as P. corallina) from Correvon et Cie. This differs from the other plants mentioned in that its leaves are completely glabrous below, and its flower (as is characteristic of young plants blooming for the first time) is somewhat smaller. The foregoing description includes all the plants mentioned.

Since this hybrid has not only been found several times in the wild state (cf. Maleev, 1. c.), but is also not infrequent in cultivation, and is, in the gracefulness of its foliage and the size and color of its flowers, one of the finest of the single peonies, a name for it seems to be desirable. It is with great pleasure that I dedicate it to Dr. A. P. Saunders, who first produced it from known parents and through whose labors so much has been learned both horticulturally and scientifically about this genus.

In order to clarify the distinctions between the various species, hybrids, and horticultural forms described above, a key to them is presented:..

P. x saundersii Stebbins, 1939

Synonymes : P. tenuifolia x P. triternata Maleev, 1947

Plante haute, feuilles à segments largement lancéolés de (4) 7 à 12 mm de large, fleurs rosé-violacé de 9 à 12 cm de diamètre, pétales largement obovoïdes de 5 cm de long et 3,5 cm de large. Floraison en mai

Hybride naturel entre P. tenuifolia et P. mascula subsp. triternata, originaire de Crimée dans les monts Dara-Bair (près de Feodosia) et Aï-Pétri près de Yalta.

P. x saundersii diffère de P. tenuifolia subsp. biebersteiniana par ses folioles plus larges et ses fleurs rosé-violacé, de même couleur que celles de P. mascula subsp. triternata.

Les premiers échantillons de cette pivoine ont été récoltés en 1930 par Vassiliev et étudiés en 1937 par Maleev qui publia seulement une description en russe. Il publia ensuite dans la Flore de Crimée (1947) la description en latin de cet hybride.

Auparavant, Stebbins (1939) avait décrit un hybride de même parenté obtenu artificiellement par Saunders aux États-Unis.

Maleev (1947) place en synonyme de cet hybride P. hybrida citée par Pallas (1795) dans le « Catalogue des végétaux spontanés observés en Tauride ». Ainsi, P. hybrida de Crimée désignerait les formes de P. tenuifolia à segments larges car Maleev la place également en synonyme de P. tenuifolia var. biebersteiniana.
