Rosales
Rosales is an order of , including nine families, the type family being the rose family Rosaceae. These nine families (see box, right) are those shown by the genetic analysis carried out by the Angiosperm Phylogeny Group to be related to each other. Their analysis showed that the old Cronquist system order of Urticales belongs within the Rosales. In the APG classification, well-known members of Rosales include: roses; strawberries, blackberries and raspberries; apples and pears; plums, peaches and apricots; almonds; rowan and hawthorn; elms; figs; nettles; and hops and cannabis. Apart from the Rosaceae itself, this is a complete change from the circumscription of the Rosales in the Cronquist system, listed below; these families have been removed to various other orders. The currently accepted family and/or order is shown in brackets: [more]
At least 59,087 species and subspecies belong to the Order Rosales.
