ITS VARIETIES, 25 
occasionally it lies along the ground, and sometimes 
produces a young plant at its extremity; as in the 
Strawberry (f. 3. 5.), when it is called a runner, or 
sometimes an offsett, as in the Stone Crop. Sometimes 
as in the Iris (pl. 9 f. 4.), the stem every year produces 
branches on one side, and roots on the other, when it is 
termed a root-stock, or rhizome, or root-like stem. 
24, There are some plants, as the Hyacinth, Onion, 
Lily, &c. which produce what are called Bulbs; these 
are commonly regarded as the roots of the several 
plants to which they belong; but such is not the case; 
for they are rather a kind of underground stem, from 
which true roots spring. 
Pl. 9. f. 5. represents the Scaly Bulb of the white 
Lily, in which a. is the stem or axis cut across; se. 
are the scales, or rudiments of leaves surrounding the 
stem; and 7. the true roots. At f. 6. is seen the coated 
or Tunicated Bulb of the Leek, in the entire state; at 
r. the true roots are seen; at ¢, the collar, or part 
between the root and stem; at se. the scales, or coats 
as they are called, which are leafy organs; and at a. 
is seen the axis or stem cut across: f. 7 is a lengthways 
cutting of the same, in which, besides the parts before 
mentioned, represented by the same letters, there 
is seen at b. a bud, or clove, which will take the 
place of the present year’s bulb in the next summer, 
when the old one will die away. F. 8. is the Solid 
Bulb as it is termed, of the Meadow Saffron, in which 
may be seen the three conditions, through which the 
plant passes; at @. is seen the part or bud which 
flowered last year; at }. that which will flower this
