separating to free several exalbuminous seeds, with rather long 

 funicles, thick coats, and fleshy embryos. All these species are 

 shrubs (usually climbing) or prickly trees 

 (fig. 45), whose alternate bipinnate leaves 

 possess numerous little unsymmetrical 

 leaflets and lateral caducous stipules. The 

 flowers form axillary or terminal racemes, 

 each flower axillary to its bract. This sec- 

 tion only includes three species, natives of 

 the warmer parts of Asia.'* 



The section Ccesalpinaritf is, on the con- 

 trary, American ; but its species are very 

 close to the last. They are unarmed, some- 

 times with large leaflets, and possess an 

 oblong or lanceolate oblique or falciform 

 pod, which in C. echinata* is covered with 

 prickles. In C. insignii and jpulcherrima, 6 the long stamina! filaments
