Great-Jlorvercd Porana. PI. twining. 



Cult. The shrubby species of Porana are well adapted for 

 training on rafters or pillars, in a stove, or warm part of a green- 

 house ; a mixture of loam, peat, and sand, is the best soil for 

 them ; and cuttings will strike root readily in the same kind of 

 soil, under a hand-glass. The annual species are hardy, and 

 grow fast when planted in a sheltered situation, and soon make 

 a good covering for a temporary arbour ; or they may be 

 trained on branches of trees ; their flowers are produced in great 

 profusion in autumn.
