journey had so far shaken off the flowers, that it was found ne- 
cessary to send the plant immediately to the artist to be figured, 
and thus an opportunity was lost to us of carefully examin- 
ing, while recent, the interior of the flower; but I am sure the 
figures of Mr. Fitch are to be depended upon; and it is hence 
evident that at the faux or mouth of the tube is an elevated large 
circular disk, velvety on the surface, apparently closing the whole 
aperture. Jam not aware of anything of the kind being found 
in other species of the genus. In general habit this species has 
some affinity with our Aristolochia Thwaitesii,* figured and de- 
scribed at ‘Tab. 4918 of this work ; but there the panicles spring 
rather from excrescences of the root than from the trunk itself, 
but those flowers exhibited no internal structure such as we here 
represent.

large elevated disk which closes the faux,—slightly magnified. 2. Style and 
stigma, with the anthers,—more magnified.

* T am glad to have the opportunity of correcting an error into which I have 
fallen, in stating that that plant was a native of Ceylon, communicated to us by 
Mr. Thwaites. An excellent friend assures us that such is not the case, nor am 
I able to trace its origin. I possess however another allied but very distinct 
new species of Aristolochia from St. Martha, New Granada (Mr. Purdie), with 
very copious panicles arising from subradicant tubercles. I think it prebable our 
plant figured at Tab. 4918 is, as well as the present, from Tropical America.
