The second division of the Sympetalce (the Anisocarpce) has 

 usually but two or three carpels, never as many as the petals. 

 The stamens are also never more than five, and very often one 

 or more are abortive.

The first order (Tubiflorce) has, as the name indicates, 

 tubular flowers which show usually perfect, radial symmetry 

 (Actinomorphism) . There are five families, all represented by 

 familiar plants. The first (Convolvulacece) has as its type the 

 morning-glory (Convolvulus) (Fig. 118, G), and the nearly
