Pestles are located, as well as at types of the previous sort, on a convex fleshy receptacle. A fruit – a mnogosemyanka. It is cultivated among many grades received as believe, on the basis of hybridization of wild strawberry virginsky – F. Virginiana and wild strawberry Chilean – F. chiloensis.
Rose wrinkled – R. rugosa. A natural area – the Far East, Kamchatka, Sakhalin, Japan, China. Outstanding object of decorative gardening, a high-vitamin and food plant (from petals produce. Are widely cultivated, winter without cover.
The majority of the spireyny live in mountains, in a forest strip and on opened, warmed up by the sun, spaces, on stony scatterings, slopes of gorges, coast of the rivers. In a forest zone they are a part of an underbrush of different types of the wood, in steppes form shrubby thickets. Some spireyny are kserofita, and can grow even in the desert.
Among the apple-tree mountain plants prevail. The majority of species of apple-trees, pears, kizilnik, mountain ashes grow in light light forests on hillsides or on mountain gorges, single derevyay or groves. In an underbrush in the lower circle of the mountain woods some of them (mountain ashes, kizilnik) rise to the upper bound of a forest belt. Representatives of the same childbirth come for a polar circle. In tropics few representatives apple-tree also live in mountains.

On the basis of distinctions, mainly in morphology of fruits and in the main chromosomal numbers, the family is divided into four subfamilies: Spireynye (Spiraeoideae) – a fruit – a leaflet, seldom a box, the main chromosomal numbers 8 and 9; Shipovnikovye (Rosoideae) – fruits – nutlets, multinutlets, multistone fruit, it is frequent with participating in formation of a fruit gipantiy, the main chromosomal numbers 7, 9, are more rare 8; Apple-tree (Maloideae) – a fruit apple, the main chromosomal number 7; Plum (Prunoideae) – a fruit a stone fruit, the main chromosomal number
