Pammel — Anatomical Characters of Seeds of Leguminosae. 167 



Cell-walls color blue with chlor-iodide of zinc. Starch is 

 absent but cells contain fat and protein. 



OXYTROPIS DEFLEXA, DC. 



PL XIII. f. 2. 



Malpighian cells do not differ essentially from those of 

 0. Lamherii. The walls of the osteosclerids are thick; the 

 nutrient layer is much compressed and thin-walled. Aleurone 

 layer prominent, followed by the thick-walled mucilaginous 

 endosperm, and the narrow, elongated, thick-walled internal 

 layer. Embryo as in last species, 



Glycyrrhiza, Tourn. 



Schleiden and Vogel, and Chalon, studied the genus with 

 reference to the presence of endosperm; the mucilaginous 

 character of this by Nadelmann. Brandis has also studied 

 the orenus. G, echinata is without starch but contains 

 an abundance of fat and protein. Endosperm is more 

 abundant in G. lepidota than in G. echinata, 



Glycyrrhiza lepidota, Pursh. 



Fl. XV. f. 6. 



Testa and endosperm 490-500 /x thick. Endosperm va- 

 riable in different parts of the seed, but usually well 

 developed. 



Malpighian. Cells 70-75 /x long. Cuticle somewhat irreg- 

 ular; the light-colored cuticularized layer is followed by 

 a narrow but sharply marked zone, the light line; cell- 

 cavity is large at the base, gradually tapering upward. Pore- 

 canals extend into wall beyond the light line. Cells contain 

 pigment and some plastic material. 



Osteosclerid. The I-shaped cells are thick-walled, with 

 small projections somewhat similar to those shown for Ervum 

 Lens by Mattirolo and Buscalioni. The intercellular space is 

 elongated. The cells attain their greatest development in 

 the hilar region. All of the cells carry some pigment and 

 plastic material. 



N'utrient. This layer is much compressed and thin-walled; 

 cells number from four to six rows. Pigment is most abun- 

 dant in the lower part of the layer.
