Suborder II. OESALPINIE^E. 
Flowers usually 5-merous, very rarely 4-merous or 3-merous, the sepals united 
at the base into a short tube, lined by the disk, bearing at its margin the petals 
and stamens, rarely forming a campanulate or tubular calyx with the stamens 
near the base, as in Papilionacece, the free part of the sepals or lobes of the calyx 
imbricate or rarely valvate. Corolla irregular or nearly regular, either with the 
5 (or 4 or 3) petals variously imbricate in the bud, but the upper one never 
outside, and usually quite inside, or in genera not Australian, some or all of the 
four lower petals wanting. Stamens 10 or fewer, or in genera not Australian, 
indefinite, free, or rarely more or less united, all perfect or several of them 
reduced to staminodia. Ovules anatropous or nearly so. Radicle of the embryo 
short and straight.

Sepals and petals 5. Stamens 10 ; anthers all perfect, opening in terminal 
pores or short slits, or some minute and empty. Leaves abruptly 
pinnate 81. Cassia. 
Sepals and petals 5. Stamens 3 with perfect anthers opening in longi- 
tudinal slits, 2 small staminodia. Leaves unequally pinnate . . . .82. Petalostyles.
