Magdalena, née Dzieduszycka, Countess Morska (1762–1847) established in the 1820’s a romantic garden at her estate in Zarzecze, which is well known to garden historians. The park has thus far been the subject of analysis because of the characteristic layout of the palace, designed by P.Ch. Aigner, and also because of the wide range of social changes introduced by Morska around the whole village of Zarzecze. Previous analyses have been concerned with the collection of plants gathered at Zarzecze. These were based on Countess Morska’s 1838 garden notes which have survived at the Ossolineum collection in Wrocław, and also in the text accompanying the published illustrations in her Collection of Pictures from the early 1830’s. From these materials one can describe the dendrological collection gathered by Morska. This collection, while similar to the other dendrological collections at Krzemieniec, Łańcut, Medyka, Niedźwiedź and Puławy, whose owners she remained in constant contact, but had a special character. For example it was Poland’s first great collection of roses. Morska collected more than 150 roses, of which 140 were cultivars, mainly of French origin. In a large scale sowing program she named the first two well known Polish cultivars of ornamental shrub – Rosa ‘Józef Dzieduszycki’ and Rosa ‘Laurenti Dzieduszyck'.

The taxonomy of the Paeonia obovata polyploid complex in E-Asia has been controversial with treatments ranging from one species and two varieties to five species and numerous infraspecific taxa. Extensive observations in the field, analysis of morphological characters based on 32 populations sampled, and the examination of a large amount of herbarium specimens show that all the characters used by previous authors for distinguishing the species are variable between or even within populations: Leaf position, petal colour, stamen number (from 21 to 110 in the red-flowered and from 58 to 239 in the white-flowered form), filament and anther colour, style length as well as follicle number and position. Therefore, all these characters are of no value for species delimitation. However, an extensive chromosome survey and the analysis of morphological characters show that the ploidy level is basically correlated with the geographical distribution and with the indumentum on the lower leaf surface. Thus, the recognition of one species with two subspecies is proposed: Paeonia obovata subsp. obovata, mostly diploid, widely distributed in the north, east and south of the distribution range and glabrous to sparsely pubescent or hirsute on the lower leaf surface, and subsp. willmottiae, tetraploid, limited to the west and with leaves densely hirsute or pubescent below.
