问：仙女木属于哪一科？你能写一些上下文来回答这个问题吗？
仙女木（学名：）为蔷薇科仙女木属的植物。分布于亚洲、欧洲、北美高山地带以及中国大陆的内蒙古自治区、吉林省、辽宁省等地，生长于海拔2,100米至2,300米的地区，一般生长在高山地带。新仙女木期, Older Dryas and Oldest Dryas 冰段 are named after "Dryas octopetala", because of the great quantities of its pollen found in cores dating from those times. During these cold spells, "Dryas octopetala" was much more widely distributed than it is today, as large parts of the northern hemisphere that are now covered by forests were replaced in the cold periods by tundra.
