Two species of Aristolochia from South America, char- 

 acterised by the wonderful tail at the tip of the ^ perianth, 

 and curious spurs at its base, have been cultivated in 

 England, and confounded with a third (A. caudata), which 

 has not hitherto been introduced. These are, first, the 

 old A. trilobata of Linmeus's first edition of the Species 

 Plantarum, taken up from Plumier's Catalogue which was pub- 

 lished in the beginning of last century ; of this, our plate is the 

 first representation from cultivated specimens. Secondly, 

 A. macroura, Gomez, a Brazilian species, figured under the 

 name of A. trilobata in the Botanical Register, t. 1399, and 

 under that of A caudata, at 1. 1453 of the same work, and at 

 t. 3769 of the Botanical Magazine. The true A. caudata,
