Cult. The greater part of the species require a moist or 
damp shady situation, but in any kind of soil. Some of the rarer 
kinds may be planted in pots, and these placed in pans of water. 
C. hirsita, and several other species, produce young plants from 
the leaves. All that is necessary is to lay the leaf on a moist 
grassy surface, or on moss kept moist. The plant propagates 
itself extensively in this way in moist soils; but the easiest and 
most certain method is by dividing the perennial species at the 
root. The annual and biennial kinds only require to be

sown in the open border in a damp situation, where they may 
be allowed afterwards to sow themselves. Many of the peren- 
nial kinds are very ornamental plants, but the annual and bien- 
nial kinds have a weedy appearance, and therefore they are only 
proper to be preserved in botanical gardens.

Cult. These plants succeed best in light sandy soil, and are 
well adapted for rock-work. The P. carndsum may be increased 
by dividing the plant at the root or by seeds. The P. Gre’cum 
by seeds, which may be either sown in the rock-work, or in the 
open boder. The Java species will require to be kept in a stove.
