known.’ 
The thorough regularity of the flower of Cadia leads us to 
consider this genus as the most perfect type to be found in the 
Leguminose (excluding Mimosee), and to 
place them at the head of this group in 
a series apart, the artificial nature of which 
does not, however, escape our notice. 
The series remaining to be reviewed will 
be referred to Cesalpiniee and Papilio- 
nacee, between which there is only one 
absolute difference. If the axillary petal, 
in Cadia usually overlapped on the one 
side and overlapping on the other, becomes overlapped on both 
sides, the plant belongs to Cesalpiniee ; if on the contrary it overlaps 
on both sides, to Papilionacee. As in Cadia we may find either 
arrangement,” we place it at the head of the two sub-orders we are 
now about to describe.

II. CAHSALPINIA SERIES. 
Cesalpinia (Fr., Brésillet—figs. 45-48), has more or less irregular 
hermaphrodite flowers. The receptacle forms a broad shallow cup, 
lined by a glandular tissue, somewhat thickened near the rim. The 
five sepals may be equal or unequal; if unequal, the anterior is the 
largest, indicating by its position that the flower is resupinate. By 
this the two lateral sepals are broadly overlapped, and they them- 
selves again overlap the two posterior, of which one is quite internal 
(fig. 47). The corolla consists of five free alternating petals, either 
sub-equal or unequal, the posterior petal being in the latter case the 
smallest, and overlapped by the two lateral petals, which are them- 
selves overlapped by the posterior pair. There are ten stamens, five
