Ohs. Cephalotus has been referred by its discoverer 

 Labillardiere to Rosacese, to which, notwithstanding its 

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

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

 wanting to determine absolutely its place in the natural 

 method. Prom the structure of its ovulum, 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 

 would differ from the greater part, but not from all the [603 

 Rosacese ; and in other respects it does not appear to 

 belong to any subdivision of that order hitherto proposed. 



In the structure of its ascidia it agrees with Nepenthes, 

 with which, however, it has no other point of resemblance. 



The ascidia or pitchers of Cephalotus were observed to 

 be in general nearly half filled with a watery fluid, in 

 which great numbers of a small species of Ant were 

 frequently found drowned. This fluid, which had a 

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