much smaller than those of the parenchyma. Reserve mate- 

 rial consists of starch, protein, and fat Rhynchosia. 



C AESALPINIE AE . 



Baubinicac. 



Cuticularized layer well developed, Malpighian cells long; 

 osteosclerids not essentially different from the parenchyma of 

 the nutrient layer; endosperm copious, cartilaginous. Sev- 

 eral rows of palisade cells in the cotyledons. Reserve food 

 material consists of fat and aleurone grains Cercis. 



Eucaesalpinieae . 



Cuticularized layer conspicuous, Malpighian cells usually 

 very long ; osteosclerids usually not essentially different from 

 the cells of the nutrient layer except that they are strongly 

 sclerotic; inner testa evident as a rule; endosperm copious, 

 cartilaginous. Usually several rows of palisade cells. Re- 

 serve food material consists of fat and aleurone grains. 



1. Palisade cells absent Gymnocladus. 



1. Palisade cells present (2). 



2. Malpighian cells very long , Gleditschia. 



2. Malpighian cells relatively short Hoffmanseggia. 



Cassieae. 



Cuticularized layer evident, Malpighian cells variable as to 

 length in different species ; osteosclerids I-shaped or like the 

 underlying sclerotic cells of the nutrient layer; inner testa 

 much compressed ; endosperm copious, cartilaginous. Coty- 

 ledons with palisade cells. Reserve food material consists of 

 fat and aleurone grains Cassia. 



MIMOSEAE. 



Amherstieae. 



Cuticularized layer not evident, Malpighian cells long and 

 thick-walled; osteosclerids not essentially different from the 

 cells of the well developed nutrient layer ; endosperm nearly 

 wanting. Parenchyma cells of the cotyledons thick-walled. 

 Reserve material consists of fat, aleurone grains and reserve 

 cellulose Tamarindus. 



Adenanthcreae . 



Cuticularized layer evident, Malpighian cells thick-walled, 

 light line above the middle of the cell; osteosclerids I-shaped, 

 small and compressed ; nutrient layer of thick-walled sclerotic 

 cells; inner integument much compressed; endosperm co
