color red very rapidly with fuchsine, making a strong contrast 

 with the nutrient layer and the rest of the endosperm. The 

 cells of the mucilaginous reserve cellulose are thick-walled, 

 with a small cavity. The middle lamella stains blue with 

 chlor-iodide of zinc when it is allowed to act for some time. 

 The mucilaginous walls color faintly at first. The internal 

 part of the endosperm consists of thick-walled elongated 

 cells. 



Embryo, Epidermal cells nearly isodiametric ; exterior 

 walls thickened ; the cells below are elongated and more 

 loosely arranged, with small intercellular spaces; two rows of 

 palisade cells occur on upper face, a third is interrupted 

 and connects with the procambial vessels. The cells contain 

 protein and fat but no starch. Walls color blue with chlor- 

 iodide of zinc. — (Sapulpa, Indian Terr., Bush, No. 1846,

Lespedeza reticulata, Pers. (L. frutescens, L., Britton.) 



Testa and endosperm 108-116//, thick. Malpighian cells 

 well developed; endosperm somewhat variable, reaching its 

 greatest development on the sides. 



Malpighian, Cells 56 /a long. Cuticle somewhat uneven; 

 cuticularized layer narrow, followed by a narrow but well 

 marked light line ; a second less sharply defined zone occurs 

 in the lower part of the Malpighian cells. Several pores ex- 

 tend into the wall below the upper light line. Cells contain 

 a large chromatophore somewhat variable as to position. 

 Yellowish pigment and tannin abundant, also smaller granules 

 of plastic material. 



Osteosderid, Cells thick- walled, 14 /-tlong, containing pro- 

 tein grains, some pigment and tannin. The intercellular 

 spaces are elongated. 



Nutrient, This layer is much compressed, the cells are 

 thin-walled, elongated, and contain a great deal of pigment 

 and tannin. 



Endosperm, Aleurone cells longer than broad. The 

 reserve cellulose below is not well developed ; all of the cells 

 contain fat and protein. 



Embryo, Cells of the first row smaller than those below,
