Great-flomered 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.
