A highly natural group of the old and very extensive Genus 
Bignonia, inhabiting Brazil and Guiana, distinguished by their 
scandent scabrous stems, ternate leaves, (or geminate with a 
simple cirrhus, in lieu of a terminal leaflet), and racemes of large, 
handsome, generally yellow, trumpet-shaped flowers, glabrous or 
pulverulento-tomentose, with large deciduous bracteas and smaller _ 
bracteoles ; the leaves, bracts, and calyces beset with conspicuous 
pateriform dark-coloured glands. These constitute the Genus ~ 
Adenocalymna of Martius, adopted by De Candolle, and so named 
from asiv, a gland; xédypa, a covering. It must be confessed 
that the species, nineteen in number, are difficult to be defined
