 a cotyledonary division is visible.

 portion of b, which remains uncoloured and has a mucilaginous 

 appearance, (f. Remains of the stalk of the ovarium, e. Sphacelated

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

 /i. 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.
