long ; cuticle even ; light line under the cuticularized layer. 

 Pigment mostly in the lower part of the cell-cavity. Osteo- 

 sclerids 12 fM long, I-shaped, thick-walled, with elongated in- 

 tercellular spaces. Nutrient layer compressed, composed of 

 somewhat elongated cells. Endosperm not strongly developed ; 

 the aleurone layer continuous, followed by several rows of 

 thick-walled cells. 



Lespedeza, Michx. 



The testa in this genus is usually yellowish. In structure 

 it is much like that of Desmodium but in some of the species 

 endosperm is more abundant than in Desmodium, Schleiden 

 and Vogel recorded endosperm for the genus, and stated that 

 it is differentiated into three parts. Chalon also indicated its 

 presence in several species of the genus. Lubbock studied 

 the germination of L. angusti folia ^ Ell., but the seed is not 

 described. Protein and fat occur in all of the cells of the 

 embryo. Starch is absent. 



Lespedeza violacea, Pers. 



Malpighian. Cells 50 //,long ; cuticle an even layer which 

 colors brown with iodine ; the cuticularized layer is light 

 colored and prominent, it colors blue rapidly with chlor- 

 iodide of zinc. The light line occurs below the cuticle, with 

 numerous pores extending into the wall below. Cell-cavity 

 somewhat irregular, large at the base, with a single chro- 

 matophore ; in addition, the cells contain a yellowish pigment 

 and tannin. 



Osteosclerid. CeUs 16-28 ix long, thick-walled and slightly 

 constricted in the middle : cell- cavity larger in the lower part 

 of the cell; the intercellular space is elongated. Walls color 

 blue with chlor-iodide of zinc. 



Nutrient, This layer is compressed. Cells thin-walled 

 and elongated. Some of the larger measure 11.2X56 /x. 

 Cells of the inner part longer than broad, thin-waUed, con- 

 taining a great deal of yellowish-green pigment. The waUs 

 color blue with chlor-iodide of zinc. 



Endosperm, The aleurone layer continuous, consisting of 

 small, thick-waUed, nearly isodiametric cells ; the contents
