figured at t. 7512 of this work. A. gigantea grows 
vigorously in the Palm House at Kew, where, trained 
against the roof, its annual shoots, which spread from a 
woody stem with corky bark, extend to a length of 15 feet 
or more. In Brazil the flowering season of this species is in 
March, but at Kew the flowers develop in August. The 
flowers are fragrant. This is the only species of Aristolochia 
in cultivation of which the same can be said; most of 
them have a disagreeable odour. : :
