sandy peat, and the remaining part loam; the loam to be in¬ 
creased at each potting, till the plants are large enough to be 
turned out in the borders of the house. They should be pruned 
back in October, and be allowed to remain rather dry till the 
following March. 
I. Sellowii is another beautiful greenhouse climber, in habit 
much resembling insignis ; the leaves are more glaucous, and 
the flowers are of a rosy lilac. It requires much the same 
treatment as recommended for insignis. 
I. tyrianthena is a beautiful dark-coloured species, of much 
dwarfer habit than either of the foregoing, requiring only a large 
pot and a wire trellis of a good size, which a strong plant will 
cover with its splendid dark crimson flowers all the summer. 
The best soil for this is a free open loam, and rotten turf; they 
require to be kept moist all the growing season, that is, from 
March till October, when they die down. The tubers should 
then be kept dry till the following February, at which time they 
should be repotted, and started on again for the next season’s 
growth. It may be increased easily by cuttings, the best time 
for which is May ; take them off as recommended for the others, 
strike them in sandy peat, in a bottom heat, and, as soon as 
struck, pot them off into a rather stronger compost; do this as 
often as they require it, and they will produce flowers by the 
following September, after which they must be treated as lor 
established plants. 
I. ficifolia is one of the latest importations of this genus, and 
a very beautiful one it is. It agrees with the last-mentioned one 
in habit and culture. 
I. Learii is now pretty well known, and deservedly so; no plant 
ever bore out the representations made of it better than this. 
The cultivation is very easy ; the best situation for it is the warm 
end of a greenhouse, though it will bloom out of doors if trained 
against a south wall, or other warm place. It requires a very 
rich soil, to be well drained; the knife may be used freely, when 
planted in the open air; it is easily propagated by cuttings, or 
layers ; cuttings may be taken during any of the summer months, 
and struck in sandy peat. If a stock is required to keep through 
the winter, the best mode is to lay them. Those plants in 
borders will produce a number of trailing stems, which are 
distinct from the upright growing ones ; each of these should be
