Question: Are Schwantesia and Cleome both flowering plants?

Context paragraphs:
Cleome: Cleome is a genus of flowering plants in the family Cleomaceae.  Previously, it had been placed in the family Capparaceae, until DNA studies found the Cleomaceae genera to be more closely related to the Brassicaceae than the Capparaceae.  The APG II system allows for "Cleome" and the other members of the Cleomaceae to be included in the Brassicaceae.

Podandrogyne: Podandrogyne is a genus of flowering plants in the family Cleomaceae.  They are closely related to genus "Cleome".

Oxystylis: Oxystylis is a monotypic genus of flowering plants currently considered a part of the cleome family containing the single species Oxystylis lutea, which is known by the common name spiny caper.  It is native to the Mojave Desert straddling the border between California and Nevada.  It grows in rocky and sandy desert habitat, often on alkaline soils.  This is an annual herb producing an erect, branching stem which may reach 1.5 meters in height.  The leaf is made up of three thick, firm leaflets 2 to 6 centimeters long, borne on a stout, straight petiole.  The inflorescence is a dense head of flowers clustered about the stem at the leaf axils, each flower with four small yellow petals.  The fruit is a small white or purple nutlet bearing the spine-like remnant of the flower receptacle.

Wislizenia: Wislizenia is a genus of flowering plants containing three recognized species native to the southwestern United States and northern Mexico.  Common names include spectacle fruit and jackass clover.  Like genus "Cleome" and several relatives, "Wislizenia" has traditionally been included in the caper family, Capparaceae, but has more recently been moved to the new family Cleomaceae.

Schwantesia: Schwantesia is a genus of plant in the family Aizoaceae.  It is named in honor of the German botanist and archaeologist Gustav Schwantes (1881 - 1960).
