A native of Buenos Ayres. We have specimens gathered 

 near that eity by Dr. Gillies, which agree entirely with the 

 plant as cultivated in the Gardens. It first appeared in 

 Europe in the Garden of Mr. Neill, near Edinburgh, a 

 tuber having been sent to that gentleman by Mr. Tweedie. 



It proves a greenhouse climber, twisting itself round 

 sticks or other plants by means of its tendrilly petioles. It 

 may be increased by cuttings, as well as by seeds, and 

 flowers about midsummer. It should have plenty of air 

 in winter. 



Our drawing was made in Mr. Knight's Nursery in July 

 last. 



* A diminutive of tropcEum, a trophy. The leaves are like ancient 

 bucklers, and the flowers resemble the helmets usually represented on 



classical trophies.
