Stem succulent in the seedling stage, soon becoming woody, 

 erect, terete, glabrous, pale green suffused with red ; 1st internode 

 varying in length from 5-8'5 cm. ; 2nd about 2*3 cm. ; 3rd 1-2 cm. ; 

 4th 8 mm. ; 5th 5 mm. ; Gth 3 mm. 



Leaves compound, cauline, alternate, stipulate, glabrous, glau- 

 cous ; leaflets articulated, deciduous, or caducous ; petiolules 

 minutely stipellate ; petioles terete, tapering upwards, glabrous, 

 glaucous ; stipules linear or re volute longitudinally and appearing 

 filiform, acute, reddish, caducous, and quite free from the petiole. 



Nos. 1 and 2. Trifoliolate, less often five-foliolate ; lateral 

 leaflets oval, cuspidate, entire ; terminal leaflet rhomboid, cuspidate, 

 obsoletely serrate along the upper half. 



Nos. 3 and 4. Trifoliolate ; lateral leaflets as in Nos. 1 and 2 ; 

 terminal leaflet obovate or subelliptic, minutely cuspidate, entire. 



Nos. 5 and 6. Trifoliolate ; lateral leaflets as before ; terminal 

 leaflet subrhomboid, trinerved, trifid, with triangular cuspidate 

 lobes or teeth, the middle one of which is much the largest, other- 

 wise entire. 



Leaves of adult (a tree of 12 feet) bipinnate or simply pinnate

Fruit and Seed. The pistil is monocarpellary with a few 

 exceptions such as Swartzia dicarpa, Pultensea obovata, and a 

 few of the Caesalpinieae where there are two carpels. From two 

 to five occur in Affonsea. The ovary is one-celled, and bears 

 usually several or numerous ovules, arranged in one or two rows 

 along the ventral suture, rarely only one ovule is present. The 

 ventral suture faces the odd petal termed the vexillum in 

 papilionaceous flowers. The ovules are superposed, arnphi- 

 tropous, or anatropous, and transversely ascending or pend- 

 ulous. The fruit is termed a legume, and is strictly so when 

 it is dry and dehisces along both the ventral and dorsal 

 suture ; but it is sometimes fleshy or pulpy, as in Tamarindus
