of the small cone are few, and not very unlike the leaves (Fig. 265). 

 In Cypress they are very thick at the top and narrow at the base, so 

 as to make a peculiar sort of closed cone. In Juniper and lied Ce- 

 dar, the few scales of tbe very small cone become fleshy, and ripen 

 into a fruit which might be taken for a berry. 



LESSON XXI. 



THE SEED. 



366. The ovules (323), when they have an embryo (or unde- 

 veloped plantlet, 16) formed in them, become seeds. 



367. The Seed, like the ovule from which it originates, consists 

 of its coats, or integuments, and a kernel. 



368. Tlie Seed-coats are commonly two (324), the outer and the 

 inner. Fig. 315 shows the two, in a seed cut through 

 lengthft'ise. The outer coat is often hard or crustaceous, 

 whence it is called the Testa, or shell of the seed ; the 

 inner is thin and delicate. 



369. The shape and tbe markings, so various in dif- 

 ferent seeds, depend mostly on the outer coat. Sometimes it fits
