I introduce .this plant, though gathered in Chili, not only 

 because it came in the same collection with the Peruvian 

 plants, but because it has hitherto been considered to be a 

 native only of Peru. — A Bignoniaceous plant, much allied to 

 this in habit, and with long fruit, but with ternate leaves, 

 found by Mr. Cruckshanks at Corillos de Uspallata, may 

 probably prove a second species of this beautiful genus.
