Pammel — Anatomical Characters of Seeds of Leguminosae. 169 



MalpigJdan. Cells 80-82 fi long. Cuticle uniformly de- 

 veloped, the narrow cuticularized layer followed by the 

 well-developed light line ; cell-cavity gradually tapering from 

 the base; pores extend much beyond the light line. Cells 

 contain plastic material. 



Osteosclerid. Cells I-shaped, with uniform, elongated, in- 

 tercellular spaces. The walls are thickened and the cells 

 contain some plastic material. 



Nutrient. This layer is much compressed, consisting of 

 three to six rows of cells containing pigment. 



Undosperm. Variable in thickness. Aleurone layer well 

 developed with thick- walled cells. Cells of the reserve cel- 

 lulose are thick-walled with large pore-canals. The walls are 

 differentiated into three parts as in Glycyrrhiza and many 

 other genera. The internal part of the endosperm consists 

 of thick-walled, elongated cells with a small cell-cavity. All 

 of the cells contain fat and protein grains. 



CoRONiLLA, Tourn. 



The genus Coi'onilla has been studied by Chalon, who 

 found endosperm uniformly present in a large number of 

 species examined by him. O. montana was studied by 

 Nadelmann, who found a small amount of mucilaginous en- 

 dosperm present, as well as starch in the cotyledons. Harz 

 noted the occurrence of starch in the cotyledons of this 

 species. The same species is described in detail by Mattirolo 

 and Buscalioni. Lubbock studied the germination of O. 

 juncea but does not describe the seed. Parts of the plant are 

 said to be poisonous, although it is used for forage. 



CORONILLA MONTANA, Scop. 

 PI. XXII. f. 2. PL XXIII. f. 3. 



1 was unable to obtain good seed of C. varia and therefore 

 substituted C. rtiontana. Testa and endosperm 125-230 /x 

 thick. Testa below the Malpighian cells usually 50 /u, thick. 



Malpighiayi. Cells 40-49 /x long, thick- walled and deep 

 brown; light line removed some distance from the cuticle. 

 When sections are treated with ferric chloride the walls and 

 contents give the reaction for tannin.
