(Fig. 702). The lower overlapping petals are somewhat larger than the upper ones. 



Of the ten stamens the three upper ones are short and sterile, while the other 



seven, the filaments of which are curved and convex below, diminish in length 



from above downwards. The anthers open by means of terminal pores. The pod 



is compressed and broad and flat. The flowers are borne in racemes in the axils 



of the leaves of the shrub, which is about a metre high. The bright green, 



equally pinnate leaves have 



small stipules at the base. 



Tamarindus indica (Fig. 703) 



is a handsome tree, native to 



tropical Africa, but now planted

shade-tree. The racemes of flowers are terminal on lateral twigs bearing equally 

 pinnate leaves. The individual flowers are markedly zygomorphic. The fruit is 

 peculiar. The pericarp is differentiated into an outer brittle exocarp, a succulent 

 mesocarp, and a firm endocarp consisting of stone-cells investing the more or less 

 numerous seeds individually (Fig. 704). The almost imperceptibly dorsiventral 

 flowers of Copaifera have no corolla ; the four sepals are succeeded by 8-10 free 

 stamens. The fruit is one-seeded but opens when ripe. The seed is invested on
