The Rosaceae or rose family is a large family of plants, with about 3,000-4,000 species in 100-120 genera. Traditionally it has been divided into 4 subfamilies (Rosoideae, Spiraeoideae, Maloideae or Pomoideae, and Amygdaloideae or Prunoideae), primarily diagnosed by the structure of the fruits, but this has not been universally followed. Recent work has identified that the traditional four subfamilies are not all monophyletic, but the structure of the family is still awaiting complete resolution. Identified clades include:

Amongst these groups Neillieae appears to be the sibling group to Maloideae, and Dryadeae may be the sibling group to Rosoideae. Other genera, for example Kerria, do not belong to any of these groups.

A tongue-in-cheek poem

The rose is a rose
and was always a rose;
But the theory now goes
That the apple's a rose,
And the pear is, and so's
The plum, I suppose.
The dear only knows
What will next prove a rose.
You, my love, are a rose,
but were always a rose.
- Robert Frost, "The Rose Family".
