185. They are formed in summer, when vegetation is vi- 
gorous, and the sap flows freely in the plant, grow a little in 
autumn, and remain stationary during the winter. In spring, 
they partake of the general impulse which vegetation receives 
from the increased heat of the earth and atmosphere, and 
begin to expand; they become gradually enlarged ; their 
scales, or hybernacula, are pushed aside, and the organs 
they protected begin to appear. In warm countries where 
vegetation is more vigorous, and the sap flows freely during 
the whole year, there is less interval between their formation 
and evolution. In the axilla of every leaf, however young, 
though still in the bud, a small conical pointed body may be 
_ observed : this is the rudiment of the bud of the succeeding 
_ Season, thus apparent more than twelve months before it is 
_ to be developed. 
186. Those which are long and pointed generally produce 
leaves and branches, and are called foliiferous. Those which | 
are larger and more rounded contain flowers, and are called _ 
Sloriferous. Some contain both leaves and flowers, and are 
called mixt, as Lilac (Syringa vulgaris). The delicate leaves 
_ within the bud are folded in many various ways: the manner 
_ of fold is termed foliation or vernation. This will be de- 
_ seribed under terminology. 
__ 187. Buds may develope on all parts of plants. Occa- 
_ Sionally they are met with on the leaf.—(See par. 223.) 
188. The Turio is the bud of perennial roots, growing 
_ from the upper part of the root, and producing the new stem. 
189. The Bulb has been described under the term “ bul- 
bous root.” It may be considered as a bud, because it con- 
tains the rudiment of the future plant ; but if we consider it
