 bedded raphe in the three angles. 

 Fi". 15 The edible nucleus, removed from fig. 13. This is the ordinary weU-known Brazil-nut. 

 Fig. 16- A transverse section of the same^ seen sideways. 

 Fig. 17* The same^ seen from above^ showing in its summit the traces of the almost obsolete minute i 



cotyledons. 

 Fig. 18. A longitudinal section of the same embryo^ showing it to be a gigantic radicle^ with an external 



exorhiza surrounding an internal neorhiza.

Fig. 1. A flower expanded. 



Fig. 2. The inferior ovary surmounted by G sepals, viewed sideways. 



Fig, 3. The same, seen from above, showing within the sepals the epigynous disk that encircles the elevated 



vertex of the ovary : all nat. size. 

 Fig. 4. A transverse section of the inferior ovary, usually 4-celled. 

 Fig. 5. A longitudinal section of the same, showing also the sepals, disk, vertex, and style, with several 



ovules in each cell, suspended by funicles from the middle or summit of the central axis : both 



somewhat magnified. 

 Pig. 6. The androphorum removed, showing its inverted head. 

 Fig. 7. The same straightened, to show the bare ligiila between the basal staminiferous ring and the hood 



echinated inside with very numerous staminiferous appendages. 

 Fig. 8. The same viewed sideways, to show the basal ring where it is agglutinated to the disk by the 



intervening claws of the petals. 

 Fig. 9. Three of the staminiferous appendages of the hood. 

 Fig. 10. Three of tlie same belonging to the basal ring : all nat. size. 

 Fig. 11. Thi-ee of the appendages of the hood^ enlarged, showing the anthers fixed on their summits. 



Fig. 12. Those of the basal ring, with the anthers before and after dehiscence : all magnified. 

 Fig. 13. One of the seeds suspended within the fruit by a large fleshy funicle, which is attached to the 



summit of the solid columella descending from the operculum : this is more clearly shown in 



Plate LVI. 

 Fig. 14. A seed without the funicle. 



Fig. 15. A longitudinal section of its thick coriaceous or ligneous testa, with its enclosed nucleus. 

 Pig. 16. A transverse section of the same, showing the several cords of the branching imbedded raphe. 

 Fig. 17. The nucleus removed, which is the ordinary Sapucaya nut; it is a homogeneous embrjo or
