XIV. BERBERIDACE^. 



I. LARDIZABALA SERIES. 



In the genus Lardizabala} (figs. 33-36) the flowers are regular 

 and dioecious. On the narrow convex receptacle are inserted the 

 calyx and corolla, both double and trimerous. The sepals are large, 

 rather fleshy, valvate or subirnbricate in the bud. The petals are 

 much smaller, and taking them as a whole, each superposed to a 

 sepal. The same is the case with the six stamens, whose filaments

are united into a vertical tube, on top of which are inserted six ex- 

 trorse two-celled anthers, of longitudinal dehiscence, and each sur- 

 mounted by an acute prolongation of the connective. 2 In the bottom 

 of the androceal tube are seen three little rudimentary carpels. The 

 perianth is the same in the female flowers as in the males ; but the 

 stamens are small and free, with sterile anthers. The gynaeceum 

 consists of three 3 free carpels superposed to the outer sepals, and 

 each formed of a one-celled ovary tapering at the top and sur-

 bale<e generally, the pollen grains are elongated 

 with three equidistant longitudinal grooves.
