 below, or into a tube, as in the Mallow Family (Fig. 286), the Passion- 

 flower (Fig. 260), the Lupine (Fig. 287), and in Lobelia (Fig 285) 



Viadelphous (meaning in two brotherhoods), when united by the fila- 

 ments into two sets, as in the Pea and most of its near relatives (Fig. 288 . 

 usually nine in one set, and one in the other. 



Triadelphous (three brotherhoods), when the filaments are united in three 

 sets or clusters, as in most species of Hypericum.
