  ROSIDAE   (Site not responding. Last check: 2007-10-20)
Een onderklasse van Magnoliopsida is Rosidae (Cronquist, 1988).
Planten in een of meer opzichten meer geavanceerd dan de Magnoliidae; stuifmeelkorrels triaperturtaat (met 3 openingen) of hiervan afgeleid, zaadlobben niet meer dan twee, meeldraden niet bandvormig, gewoonlijk met duidelijke helmknop en -draad, planten produceren zelden benzylisoquinoline of aporfine alkaloïden, wel vaak andere alkaloïden, looistoffen, betalaïnes, mosterdoliën of iridoïde bestanddelen.
In plaats van onderklassen zijn hier nu superorden ingevoerd en is bijvoorbeeld de onderklasse Rosidae veranderd in de superorde Rosiflorae.

 Rosidae --  Encyclopædia Britannica   (Site not responding. Last check: 2007-10-20)
Rosidae is 1 of the 6 subclasses in the class Magnoliopsida.
Rosidae includes the largest number of families of all the subclasses, although the vast majority of species belong to only 5 large orders: Fabales (18,000), Myrtales (9,000), Euphorbiales (8,000), Rosales (6,600), and Sapindales…
There are two theories on the evolutionary origin of the Rosidae; in both scenarios the Rosidae arise eventually from the Magnoliidae, but in one theory they arise from that subclass directly, while, in the other, a stage interposed between the two subclasses resembles the Hamamelidae in having reduced flowers and a loss of petals.

 PBIO 450 Lecture Notes - Rosidae -- Spring 1998
Based on the rbcL data, the family seems to be close to the Theanae (Ochnaceae) and Violanae (Violaceae, Passifloraceae) of the Dilleniidae, and the Rosanae (Chrysobalanaceae) and Geranianae (Linaceae, Humiriaceae, Erythroxylaceae, Malpighiaceae and Trigoniaceae) of the Rosidae.
Given the seemingly close molecular relationship between the Passifloraceae and the Euphorbiaceae, however, I have adopted Takhtajan's (1997) placement of the Euphorbianae in the Dilleniidae rather than retain the family in Cronquist's Rosidae.
This shrub or small tree, known best by the common name "jojoba" or less often as "goatnut," is the source of an important oil used in fine lubricants.

 Rosidae
The Rosidae has been distinguished from the Dilleniidae in that species with numerous stamens have the stamens initiated in centripetal (rather than centrifugal) sequence and usually do not exhibited parietal placentation which is common in Dilleniidae.
Molecular phylogenetic studies indicate that the Rosidae are a natural group only if a large portion of the subclass Hamamelidae and most Dilleniidae are included in it.
The Proteaceae should be moved to the "lower hamamelids." The two orders Cornales and Apiales are related to lineages of the Asteridae as suggested by previous morphological and chemical studies.
