Suborder II. C^salpinie^b. (By Prof. Oliver.) 



Flowers irregular, more rarely regular, 5-merous. Sepals 5, 2 pos- 

 terior sometimes coherent throughout, connate below or free to the 

 base, imbricate or rarely valvate, occasionally spathaceous, rarely ob- 

 solete or reduced to minute scales. Petals 5 or fewer by abortion or 0, 

 posterior included in aestivation. Stamens 10 or fewer by abortion, 

 rarelv more, free or mon- or diadelphous; anthers various. Ovary 

 sessile or stipitate, stipes often adnate to the calyx-tube. Seed various, 

 with or without albumen. — Trees, shrubs, or rarely herbaceous. Leaves 

 alternate, usually pinnate (leaflets alternate or uni-multijugate) or 

 bipinnate, more rarely unifoliolate or simple. Inflorescence very 

 various.

 Africa. Of these 12 or 13 are peculiar.
