Obs. Ceplialotus has been referred by its discoverer 

 Labillardiere to Rosacese, to which, notwithstanding its 

 coloured calyx and tlie absence of petals, it seems to have 

 the nearest aftinity ; a knowledge of the fruit, however, is 

 wanting to determine absolutely its place in the natural 

 method. From the structure of its ovuluni, even in the 

 unimpregnated state, I entertain no doubt that the radi- 

 cule of the embryo points to the umbilicus of the seed 

 and therefore downwards ; a circumstance in which it 

 w^ould differ from the greater part, but not from all the [002 

 Rosacese ; and in other respects it does not appear to 

 belong to any subdivision of that order hitherto ])ropose(]. 



In the structure of its ascidia it agrees with Nepenthes, 

 with w hich, how^ever, it has no other point of resemblance. 



The ascidia or pitchers of Cephalotus were observed to 

 be in general nearly half tilled with a w^atery fluid, in 

 wdiich great numbers of a small species of Ant were 

 frequently found drowned. This fluid, which had a 

 slightly sweet taste, may possibly be in part a secretion of
