Abstract
This is an attempt to outline a consensus taxonomy for the dog-roses (Rosa sect. Caninae) of northern, western and central Temperate Europe, including the British Isles, by combining the characteristics of the main British and Continental systems in use today. It involves adopting the slightly narrower species concept of the Continent with the wider recognition of hybrids followed in Britain. The proposed system is based on the traditional view of species of dog-roses; it is considered premature to attempt a ‘phylogenetic’ system based on the highly fragmentary data that are so far available.
Highlights
We unanimously concluded that differences in the floras are relatively minor
Subspecies have been used, for example, in R. villosa, R. caesia and R. dumalis/R. vosagiaca, but they have all been treated at species level in the past and we shall consider them as such
Agrestis; R. micrantha & R. gremlii/henkeri-schulzii included in R. rubiginosa; R. mollis included in R. villosa; R. sherardii & R. pseudoscabriuscula included in R. tomentosa agg.; R. stylosa, R. obtusifolia/balsamica, R. caesia, R. dumalis/vosagiaca, R. corymbifera, R. subcanina & R. subcollina included in R. canina agg.)
Summary
We unanimously concluded that differences in the floras are relatively minor. In Britain there is no R. elliptica or R. inodora, and the Netherlands lack R. stylosa and R. mollis. Agrestis; R. micrantha & R. gremlii/henkeri-schulzii included in R. rubiginosa; R. mollis included in R. villosa; R. sherardii & R. pseudoscabriuscula included in R. tomentosa agg.; R. stylosa, R. obtusifolia/balsamica, R. caesia, R. dumalis/vosagiaca, R. corymbifera, R. subcanina & R. subcollina (and the Central European R. abietina) included in R. canina agg.).
