196 CHILODIA SCUTELLARIOIDES. 
both by placing an abundance of potsherds in the bottom of the pot, and also by 
mingling small pieces of them, or of broken sand-stone, with the soil. It is very 
susceptible of injury from any superfluity of moisture about the roots, therefore 
water should be applied sparingly aud with due discrimination. 
If it were kept in a heath-house, and treated as the Heaths, (soil alone 
excepted,) there can be little doubt that it would thrive in great perfection, and its 
pretty purple blossoms will exhibit themselves during the greater part of the 
summer months in very pleasing profusion. 
In its propagation, cultivators have experienced some difficulty, but cuttings of 
it will strike (though slowly) if planted in sand, and one principal reason why they 
do not produce roots more speedily is their tendency to flower after being planted 
as cuttings. If the flower-buds be timely removed, and the cuttings judiciously 
treated in other respects, they w^ill most probably succeed better than they have 
hitherto done, and the plant become a common ornament to our collections. 
Seeds are occasionally ripened, but the produce from them has been very 
inconsiderable, and this is by no means so certain and expeditious a mode of propa- 
gation as that by cuttings. . 
The collection of Messrs. Rollison, of Tooting, furnished the subject of the 
present drawing, from whom, and from Mr. Young, Epsom, plants of it may be 
procured for a trifling sum. 
The generic name is taken from cheilos^ a lip, and odous, a tooth, in allusion to 
the indentation in the lower lip of the calyx.
