86 Mr. Griffith on the Development of 



far exceeding in bulk the embryo itself, in which the first trace of 

 a cotyledonary division is visible. 



Fig. 4. Central and longitudinal section of a ripe fruit, a, b. The two divi- 

 sions of the tissue of the calyx now nearly similar, c, c. The basilar 

 portion of b, which remains uncoloured and has a mucilaginous 

 appearance, d. Remains of the stalk of the ovarium, e. Sphacelated 

 communicating line, reaching to the apex of the radicle and tra- 

 versing the original suspending process/", of the albumen g, of which 

 two large ascending, and two minute descending cornua are visible. 

 h. Embryo, with its radicle situated between the ascending cornua 

 of the testa. 



Fig. 5. Capsule separated : the white lines represent its denser angles, from 

 which processes are sent out into the albumen ; alternating with 

 these are six furrows, along which the texture of the capsule, here 

 very fine, dips into the albumen. 



Fig. 6. The albumen and embryo removed from the integument ; the albumen 

 is 6-cleft, the fissures at its apex being acute : between the corre- 

 sponding basilar obtuse ones, and projecting beyond them, is the 

 truncate subpeltate radicle. 



Fig. 7. Transverse section of albumen and cotyledons. 



Fig. 8. Embryo detached. 



Fig. 9. The same ; its cotyledons, which are always distinct, being separated. 

 The very small plumula is not visible. 



The whole of the figures of this plate refer to one species.

 changes that take place after the application of the ripe fruit to the 

 bark of a tree. 



Fig. 4. Embryo of the same more advanced in germination ; the commence- 

 ment of the " sucker" is now visible.

 first changes in situ.
