h. The Ripe Seed and Fruit 



The seeds of the Lilies are arranged in six rows in 

 the fruit, two rows in each compartment ; they are 

 packed very close to- 

 gether, and are flattened, 

 so that each row has 

 somewhat the appear- 

 ance of a pile of coins >(j, 

 (Fig. 92, /') Fig. 91 

 shows the section paral- 

 lel to the broad side of 

 the seed. Each seed 

 has a firm, thick testa, 

 formed from the two 

 integuments of the ovule, 

 the outer of which con- 

 stitutes the thicker and 

 harder layer. 



The ripe seed, there- 

 fore, consists of three

 the seeds being shed ; j, seeds in

 the fertilised ovum ; (2) 

 the endosperm, or tissue 

 formed inside the em- 

 bryo-sac, also in conse- 

 quence of an act of 



fertilisation ; (3) the
