[The Sub-order Mimosece is subdivided into five tribes by Bentham : 



TRIBE I. PARKIER. Calyx-teeth short, broad, imbricate. Corolla 5-fid. Stamens (perfect) 

 5-10 ; anthers crowned with a deciduous gland. Parkia, Pentaclethra. 



TRIBE II. ADENAXTHEREJE. Calyx valvate. Stamens free, usually twice as many as the 

 petals ; anthers usually crowned with a stalked gland ; pollen-grains many, distinct. Entada, 

 Piptadenia, Adenanthera, Prosopis, Dichrostachys, Neptunia, &c. 



TRIBE III. EUMIMOSE^E. Calyx valvate, pappose, or 0. Stamens free; anthers eglandular; 

 pollen-grains many, distinct. Desmanthus, Mimosa, Schranckla, Leuccena, Xylla, &c. 



TRIBE IV. ACACIEJ:. Calyx valvate, rarely 0. Stamens indefinite, usually many, free or 

 connate at the base ; pollen-grains aggregated in 2-6 masses. Acacia. 



TRIBE V. I \<,I..K. Calyx valvate. Stamens indefinite, rarely 10-15, connate at the base, 

 i-aroly beyond the middle ; anthers small ; pollen-grains usually aggregated in 2-6 masses. 

 Calliandra, Albizzia, Pithacolobium, Tnga, Affomea, &c. En.] 



SUB-ORDER II. SWARTZIEM, D.C.* 



Unarmed TREES. LEAVES unequally imparipinnate or simple, stipulate. 

 FLOWERS 5 , sub-irregularly racemed. CALYX valvate in sestivation, 4-5-lobed, or 

 rarely splitting along one side (Zollernid). PETALS more or less unequal, imbricate 

 in sestivation, 5-3-1, sometimes 0, generally hypogynous, rarely perigynous (Aldina). 

 CARPEL solitary. OVARY 1-celled, stipitate. POD 1 -celled, 2-valved, few-seeded, 

 rarely an indehiscent drupe (Detarium). EMBRYO exalbuminous.
