| Résumé : |
History of the classification of the genus Spiraea (spirea, Rosaceae) with a view to the infrageneric division is given. Spireas have been used as ornamental flowering shrubs in Europe for more than 250 years. Significant quantity of spirea taxa cultivated in Bohemia, Moravia and Slovakia was found on the basis of old herbarium evidence, historical documents and living plants. A taxonomic revision of spireas cultivated in, or documented from Bohemia, Moravia and Slovakia was made in accordance with original literature and study of natural herbarium material of most species, and with field study of many taxa mostly in SE Asia, undertaken during eleven authors’ expeditions to China and Japan (where majority of species is native). Many of old determinations of spirea species in the cultivation, or in its herbarium evidence were found to be incorrect. About 70 taxa of living plants of spireas from the territory of former Czechoslovakia were collected (mostly propagated vegetatively) in the Dendrological garden of the Research Institute of Ornamental Gardening at Průhonice near Praha in the 1980’s. This spirea assortment was being evaluated for six or eight years from horticultural points of view concerning phenological data, growth and habitus, aesthetic characterization, tolerance to winter frosts and extent of damage by aphids. Three categories of gardening prosperousness of evaluated clones were established. Systematic treatment of all taxa of the genus Spiraea found to be cultivated, documented or mentioned from Bohemia, Moravia and Slovakia is given together with drawings of 78 attested taxa. All taxa given are divided into two groups: the group of natural species with their subspecies, varieties and directly derived cultivars, and the group of cultural taxa in the rank of species (interspecific hybrids or hybrid cultivars). Altogether 42 natural species (more than 100 taxa in total) were attested to be cultivated in the territory of Bohemia, Moravia and Slovakia since about the mid-19th century. Three taxonomic changes are proposed: Spiraea mongolica Maxim. (known from China) is treated as a synonym of Spiraea lasiocarpa Kar. & Kir. (known from Central Asia from the territory of former Soviet Union); Spiraea fritschiana Schneid. var. microgyna (Nakai) Businský and Spiraea ×pseudosalicifolia Silverside ‘Triumphans’ are newly combined. Four new hybrid cultivars, Spiraea ‘Green Moundlet’, Spiraea ‘Leafy Carmine’, Spiraea ‘Ludmila’, and Spiraea japonica ‘New Pruhonice’, some cultivated under incorrect names for many years, are described. |
