Cuur. About one hundred and fifty species of Passiflora are 
now described, which, with very few exceptions, are natives of 
the West Indies and the continent of America, chiefly within or 
near the tropics. Many of them have long been cultivated in 
this country, but none are sufficiently hardy to endure the low 
temperature of our winters, except the well-known and widely 
diffused Passiflora cerulea, which is recorded to have been cul- 
tivated in this country 152 years ago. It is stated to be a 
native of Brazil and Peru ; its hardiness is therefore remarkable, 
seeing that we have many otlfer species from those countries, all 
of them requiring to be grown either in the greenhouse or stove. 
The present species must be grown in the stove. Being, like its 
allies, a free and rambling grower, it is well adapted for covering 
trellis-work against back walls, and for training up pillars or 
rafters’; but where so much space cannot be afforded, it will 
grow and flower freely if planted in a middle-sized pot and 
trained on a wire trellis. In order to keep it within due bounds, 
it is necessary, in winter, to prune and cut back the superfluous 
growth of the previous summer; this will cause it to flower 
more abundantly. Any kind of light open soil suits it; and it 
is propagated by cuttings planted under a bell-glass, and treated 
in the usual way. J. 8.
