Cadia varia. 



the brandies or axillary to the upper leaves. Two species are 

 known. 1 



The thorough regularity of the flower of Cadia leads us to 

 consider this genus as the most perfect type to be found in the 

 LeguminoscB (excluding Mimosea), 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 Casalpiniece and Papilio- 

 nacece, 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 Caesalpiniea ; if on the contrary it overlaps 

 on both sides, to PapilionacetB. As in Cadia we may find either 

 arrangement, 2 we place it at the head of the two sub -orders we are 

 now about to describe.

II. C-ESALPIXIA SERIES. 



Casalpinia 3 (Fr., Bresittet — figs. 45-4S), 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
