中国是蔷薇、月季的老家，却被外国人发扬光大了！

其实很多rose的老家不是中国，就像很多中文搜索里出现很多植物，原产地只显示中国，很不严谨。
The genus Rosa is subdivided into four subgenera:
Hulthemia (formerly Simplicifoliae, meaning "with single leaves") containing one or two species from southwest Asia, R. persica and R. berberifolia (syn. R. persica var. berberifolia) which are the only roses without compound leaves or stipules.
Hesperrhodos (from the Greek for "western rose") has two species, both from southwestern North America. These are R. minutifolia and R. stellata.
Platyrhodon (from the Greek for "flaky rose", referring to flaky bark) with one species from east Asia, R. roxburghii.
Rosa (the type subgenus) containing all the other roses. This subgenus is subdivided into 11 secti**.
Banksianae - white and yellow roses from China
Bracteatae - three species, two from China and one from India
Caninae - pink and white species from Asia, Europe and North Africa
Carolinae - white, pink, and bright pink species all from North America
Chinensis - white, pink, yellow, red and mixed-color roses from China and Burma
Gallicanae - pink to crimson and striped roses from western Asia and Europe
Gymnocarpae - a small group distinguished by a deciduous receptacle on the hip; one species in western North America (R. gymnocarpa), the others in east Asia
Laevigatae - a single white species from China
Pimpinellifoliae - white, pink, bright yellow, mauve and striped roses from Asia and Europe
Rosa (syn. sect. Cinnamomeae) - white, pink, lilac, mulberry and red roses from everywhere but North Africa
Synstylae - white, pink, and crimson roses from all areas |
