upper zone and close-fitting operculum are 3f in. in diam., the latter 1^ in. hio-\ its 



attached columella fills the much -thickened mouth (which is contracted to a breadth of 

 24 in.), and extends downwards for a length of 2 in. ; the pericarp is -J in. thick, its internal 

 diam. 3f in., its depth 3 in. ] seeds If in. long, f in. broad. 



We find here another instance of the unfortunate guesses of Dr. Berg in respect to 

 his synonyms : in the Plor. Bras. p. 482, he regarded the Z. minor of Yelloz (non Jacq.) 

 as identical with his L. lanceolata (non Poir.) : in his supplementary memoir in the 

 Linnjca (vol. xxvii.) he abandoned that synonym, and applied it to his L. Fohlii {I. c. 



p. 452); but this latter is c^uite as unjustifiable as the former, as I have elsewhere 

 bhown.

Tlie above fruit corresponds well with Marcgraaf s Jacapucaya ; and I have no hesi 



ffirniing their identity. The pyxidium (Plate XLVIII. fig. 1) is 5} in. long, 6 



IT! diam. below the calycary zone, and 6i in. across it, which is U in. above the 



O 



base ; the interzonary band is IJ in. high ; tlie upper zone 3f in. in diam., the mouth 

 f m. thick, is contracted to a diameter of 2i in. ; the operculum is 1 in. high, and its 

 iharp margin fits so closely to the upper zone, that it is difficult to introduce the edge 

 of a knife between them ; it is thickened below by the body of the columella, which fiUs

 pericarp is 1 m. thick, as dense as ironwood, the internal cavity (showing the vestiges 

 of 4 dissepiments) is 3f in. deep and 4 in. in diam. ; the seeds are IJ in. long, i in. broad, 

 * - testa thick and hard, the nucleus white and edible. I found some of them beginning 



sprout at both extremities 



Marcgraaf describes it as a very lofty tree, with a very hard timber, covered by a grey 

 k. It 18 probably the same which Gardner saw (Trav. p. 92), who describes an 



ennrmously large tiec, the ground beneath it being covered with the fruits, the large 

 coTerhda of which had fallen off on the ripening of the seeds : most of them were
