smaller than the underlying parenchyma cells, containing no 

 starch; second row of cells intermediate between the epider- 

 mal cells and the parenchyma below. Palisade parenchyma 

 wanting. Procambial bundles large, yellowish in color. 

 Starch grains vary from 17.6X28-141X6.6-28X42 fx. 



DOLICHOS, L. 



Studies of the genus have been made by Godfrin, Schleiden 

 and Vogel, Harz, Haberlandt, and Mattirolo and Buscalioni. 

 All of the writers studied forms of D, Lablab. Schleiden and 

 Vogel as well as Chalon state that the seeds are exalburainous, 

 but Harz found endosperm sparingly present. The seeds of 

 the species are used in tropical countries like the seeds of 

 Vigna and the Soy bean.

PI. XXXIII. f.4. 



Malpighian. Cells 125-135 /* long ; walls strongly thick- 

 ened ; light line close under the cuticle ; cuticularized layer 

 but slightly developed; pore-canals extend considerably 

 beyond the light line. Several chromatophores are present in 

 the cavity. 



Osteosclerid. Cells large, 40-52 fi long; walls not strongly 

 thickened. Large intercellular spaces separate adjoining 

 cells. 



Nutrient. Layer much compressed; cells with compara- 

 tively thin walls. 



Endosperm. Sparingly present, reduced to the aleurone 

 layer. 



Embryo. Epidermal cells much smaller than the paren- 

 chyma ; cells of the second row larger than those of the first 

 row, but smaller than the parenchyma cells. 



Epidermal cells contain a number of aleurone grains but 

 starch is absent; the parenchyma below has an abundance of 

 starch. The grains are similar to those of Vigna. They 

 vary from 10 to 21 /*, occasionally some 35-40 [i. The epi- 

 dermal cells of the superior face of the cotyledon are much 

 smaller than the underlying parenchyma ; they contain no 

 starch, but well-developed aleurone grains. Palisade paren-
