  Rosaceae - Encyclopedia, History, Geography and Biography
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.
To these are added the woody genera Lindleya and Vauquelinia, which share a haploid chromosome count of 17 (x=17) with the pomiferous genera, Kageneckia, in which x=15, and the herbaceous genus Gillenia (x=9), which is the sibling to the remaining maloids.
Subfamily Amygdaloideae (or Prunoideae): Traditionally those genera whose fruits consist of a single drupe with a seam, two veins next to the seam, and one vein opposite the seam.

- Phylogenetic studies in the Amygdaloideae (Rosaceae) using ITS and ndhF sequences.
The relationships among the members of the economically important subfamily Amygdaloideae (Rosaceae) are in need of a phylogenetic reappraisal.
Sequences of the ITS regions of nrDNA and the ndhF gene of cpDNA were employed to reconstruct the phylogeny of the subfamily, and evaluate the traditional classification schemes of this group.

SEM and light microscopy were used to examine floral development within the Amygdaloideae, Spiraeoideae, and Maloideae to look for ontogenetic evidence for one these hypotheses.
Manuscripts from the Amygdaloideae and Spiraeoideae floral development studies have been published in the International Journal of Plant Sciences.
The study of floral development also led to the collection of a number of micromorphological characters that are used in a non-molecular cladistic analysis.

The only exclusion was made for three Amygdaloideae  species because of importance of their data (to this, the three species become classified as separate genera not long ago and have been included in Prunus rather artificially).
The distinction between S-alleles in Maloideae and Amygdaloideae goes far beyond a usual shift with molecular clock and can be explained with functional reason or genome duplication.
This hypothesis is partially confirmed by the recognized fact of polyploidy origin of the apple subfamily having 2n=34 (while Amygdaloideae have 2n=16).

One line of attack on problems like these has been to estimate phylogenies for the family as a whole, or for individual subfamilies, tribes, and some of the larger genera.
Molecular data support recircumscription of the two largest subfamilies (Maloideae and Rosoideae), rejection of Amygdaloideae and Spiraeoideae because they are not monophyletic, and redefinition of many of the tribes.
These studies offer insights not only about the monophyly of these groups and their relationships with each other, but also about their origin, as in the case of subfamily Maloideae.

A Phylogenetic Analysis of Prunus and the Amygdaloideae (Rosaceae) Using ITS Sequences of Nuclear Ribosomal DNA, 150-160
Abstract: The economically important plum or cherry genus (Prunus) and the subfamily Amygdaloideae of the Rosaceae have a controversial taxonomic history due to the lack of a phylogenetic framework.
Phylogenetic analysis using the ITS sequences of nuclear ribosomal DNA (nrDNA) was conducted to construct the evolutionary history and evaluate the historical classifications of Prunus and the Amygdaloideae.

The four subfamilies are the Spiraeoideae, Maloideae, Rosoideae, and Prunoideae (Amygdaloideae).
I would like to give a brief overview of the work that I have undertaken concerning the subfamily Maloideae and the other subfamilies of the Rosaceae for the Flora of China.
In the subfamily Prunoideae (Amygdaloideae), the generic delimitation of the genus Prunus is also in dispute.

All members of subfamily Amygdaloideae are woody plants, either trees or shrubs.
While there are perhaps five genera that belong to the Amygdaloideae, the vast majority of species are in the genus Prunus.

This same bark pattern also is found in some species of Maloideae.

While pinnately compound leaves occur in both of these subfamilies, they are uncommon in each subfamily.
The simple leaves of some species of Maloideae greatly resemble the leaves of some species of Amygdaloideae, while leaves of other Maloideae show similarities to Spiraeoidae.
Based on a number of factors--chromosome number, bark, and leaves being but three examples--many systematists support the hypothesis that subfamily Maloideae is of hybrid origin between some ancestral Amygdaloideae and an ancestral Spiraeoideae.
