Cradling, involventia. The leaflets of a trifoliolated leaf

which hides the flowers. Lotus ornithopodioides. 
Diverging, diver gentia. The leaflets of a trifoliolated leaf 
rise up and come near each other by their base, but further 
separated by their tips. Mclilotus. 
Hanging, dependentia. The leaflets of a compound leaf 
fall below their footstalk, and turn their tip to the ground. 
Oxalis. 
Turning, invert entia. The leaflets turn half round on 
their footstalk, so that the upper face of the leaflets is turned, 
where the lower face was, and vice versa. Cassia. 
Tiling, imbricantia. The leaflets, directing their tips 
towards the top of the leaf, apply themselves to the foot-

Bent back, retrorsa. The leaflets, directing their tips to
