The Superorder Rhamnanae is further organized into finer groupings including:
- Order (1): Rosales
Rosales is an order of flowering plants. It is one of the four orders in the nitrogen-fixing clade of the fabids and is sister to a clade consisting of Fagales and Cucurbitales. It contains about 7700 species, distributed into about 260 genera. Rosales comprises nine families, the type family being the rose family, Rosaceae. The largest of these families are Rosaceae (90/2500) and Urticaceae (54/2600). Rosales is divided into three clades that have never been assigned a taxonomic rank. The basal clade consists of the family Rosaceae; another clade consists of four families, including Rhamnaceae; and the third clade consists of the four urticalean families. [more]
At least 92,443 species and subspecies belong to the Order Rosales.
