2. Revolute (revolutiva, revoluta) ; when the edges are rolled 
backwards spirally on each side (^Link) ; as in the leaf of the 
Rosemary. 
3. Obvolute (obvolutiva, obvoluta, Link ; semi-amplexa, De 
Cand.); when the margins of one alternately overlap those of 
that which is opposite to it. 
4. Convolute {convolutiva^ convoluta) ; when one is wholly rolled 
up in another, as in the petals of the Wallflower. 
5. Supervolute (^supervolutiva) ; when one edge is rolled in- 
wards, and is enveloped by the opposite edge rolled in an 
opposite direction ; as the leaves of the Apricot. 
6. Induplicate (irtduplicativa) ; having the margins bent abruptly 
inwards, and the external face of these edges applied to each 
other without any twisting ; as in the flowers of some species 
of Clematis. 
7. Conduplicate {conduplicativa, condiiplicatci) ; when the sides 
are applied parallelly to the faces of each other. 
8. Plaited (^plicativay plicatd) ; folded lengthwise, like the plaits 
of a closed fan ; as the Vine and many Palms. 
9. Replicate {replicativd) ; when the upper part is curved back 
and applied to the lower ; as in the Aconite. 
10. Curvative (curvativa) ; when the margins are slightly curved, 
either backwards or forwards, without any sensible twisting.

11. Wrinkled (corrugata, corrugativa) ; when the parts are folded 
up irregularly in every direction ; as the petals of the 
Poppy. 
12. Imbricated {imbricativa, imbricata)\ when they overlap each 
other parallelly at the margins, without any involution. This 
is the true meaning of the term. M. De Candolle applies it 
in a different sense. {Theorie^ ed. L, p. 399.)
