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. hirsiita, 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. carnbsum may be increased 

 by dividing the plant at the root or by seeds. The P. Gree'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. 



XV. DENT A' RIA (from dens, a tooth ; tooth-like structure
