bean runs into numerous varieties. Starch is absent. An 

 abundance of fat and aleurone. Endosperm is sparingly 

 developed. 



Glycine hispid a, Maxim. 



PI. XXXII. f. 9-9b. PL XXXIII. f. 5-6. 



Malpighiaii. Cells 50-60 ii long, the longest in the hilar 

 region. Light line situated somewhat above the middle; 

 cavity large at the base, gradually tapering upward. In dark 

 colored varieties these cells are abundantly pigmented. 



Osteosclerid. Cells 27-50 ix long, 1-shaped. In hilar 

 region nearly as long as the Malpighian cells, with large 

 intercellular spaces. 



Nutrient. The layer is much compressed, consisting of 

 two parts : the outer, of larger cells more loosely arranged ; 

 the inner, of thin-walled and smaller cells. The cells of the 

 nutrient layer are pigmented. 



Endosperm. Endosperm is sparingly developed, the aleu- 

 rone cells are large and contain protein. The remainder 

 consists of thick-walled cells which contain small amounts of 

 protein. 



Embryo. The epidermal cells are smaller; exterior walls 

 thickened, otherwise the walls of the cotyledons are thin. 

 The cells underneath the epidermis of the inner face are larger, 

 but much shorter than the underlying parenchyma ; the third 

 row of cells long; several rows of palisade cells on the superior 

 face. The embryo contains no starch, but an abundance of 

 fat and protein. The aleurone grains are imbedded in the oil 

 plasma. 



Ehynchosia, Lour. 



Endosperm reduced. Chalon states that the seeds are ex- 

 albuminous. The cotyledons contain an abundance of starch, 

 the grains of variable size. R. glandulosa was studied by 

 Schleiden and Vogel. 



Ehynchosia latifolia, Nutt. 



PL xrii. f.4. 



Testa and endosperm 150-166 /* thick. The osteosclerids 

 contain a great deal of pigment. 



Malpighian. Cells 72-74 /tt long, with very little pigment.
