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. -
