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

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



Tribe III. EuMiMOSSiE. — Calyx valvate, pappose, or 0. Stamens free; anthers eglandular; 

 pollen-grains many, distinct. Desmanthus, Mimosa, Schranclcia, Leuccena, Xylia, &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. Ingejb. — Calyx valvate. Stamens indefinite, rarely 10-15, connate at the base, 

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