that he originally planted it in his 'conservatory, a peach- 

 house, and a stove ; only those in the latter lived. From 

 one of them planted in rich soil under the pavement at the 

 back of the stove, the flowers were obtained. It is of 

 vigorous growth, armsful of it being annually destroyed to 

 prevent its overrunning the house. 



It strikes very readily from cuttings. 



Huge as are the flowers of this species, they yield in 

 size both to A. cordiflora and gigantea, in which the 

 blossoms are from 15 to 16 inches across, being large 

 enough to form hats for the Indian children, who amuse 

 themselves with them. 



The internal structure of the stem of this, and of all 

 other Aristolochias that we have examined, is in some 

 measure at variance, and that in a very remarkable manner, 

 with other Dicotyledonous plants. It is not improbable 

 that this structure, which prevails not only in Trichopodium* 

 and Bragantia,-\ but also in Trimeriza,\ an unpublished 

 Ceylonese genus, may serve to combine a small number 

 of orders that are in some respects different from either 

 Monocotyledones or Dicotyledones. At least it confirms 

 the correctness of Dr. Brown's approximation of Nepenthes 

 to Aristolochiae, an approximation in which we formerly 

 did not concur. J. L.
