POSTSCRIPT. 



After the above memoir was in type, I received from my friend Sen' Mattos entire 

 specimens of ripe frnits of Lecythis preserved in spii'its, which serve to throw additional 

 light upon the carpological structure of that genus. The specimens of L. tojrmia, 

 alluded to in p. 218, were mere portions of a pyxidium, intended to show the existence 

 of the large funicle attached to each seed: but they were insufficient to enable me to 

 dctcrmme whether the attachment was at the base or near the summit of the columeUa , 

 and in deciding between these alternatives the wrong inference was drawn. As tne 

 fruit, from its great weight, always hangs in an inverted position, the seed^ "I V^^^'' 

 tudinal section of the specimen appear, as in their natural growth, suspended ; hut w en 

 the fruit is placed in an erect posture, the seeds then stand upon their large tunicies, 

 which are attached to the base of the columella, as they are correctly shown m I'late u . 

 In consequence of this explanation the following corrections are needed ;
