These are arranged under the heads of Estivation, or the 
relation which organs bear to each other in the bud state ; 
Direction, or the relation which organs bear to the surface of 
the earth, or to the stem of the plant which forms the axis, 
either real or imaginary, round which they are disposed ; and 
Insertion, or the manner in which one part is inserted into, or 
adheres to, another. 
1. Of Estivation. 
The term estivation, or prcefloration, is applied to the parts 
of the flower when unexpanded ; and vernation is expressive 
of the foliage in the same state. The ideas of their modifi- 
cations are, however, essentially the same. 
1. Involute {involutiva, involuta); when the edges are rolled 
inwards spirally on each side (Link) ; as the leaf of the apple.
