CH AP. XVI. 
Of FoLiaATION. 
Y FOLIATION is to be underftood 
the complicate or folded State the Leaves 
are in, whilft they remain concealed within 
the Buds of the Plant *. Leaves, in refpect 
to the Manner of their Complication, are 
either, 
INVOLUTE, rowled in; when their 
lateral Margins are rowled fpirally inwards 
on both Sides ; asin Lonicera, Diervilla, Eu- 
ouymus, Rhamnus catharticus, Pyrus, Malus, 
Populus, Plumbago, Viola, Commelina annua, 
Plantago, Alifma, Potamogiton natans, Nym- 
phaa, Saururus, After annuus, Humulus, Ur- 
tica, Hepatica, Sambucus ebulus, and Sta- 
phylea. 
REVOLUTE, rowled back; when their 
lateral Margins are rowled fpirally back- 
wards on both Sides ; as in Rof/marinus, Teu- 
crium marum, Dracocephalon, Digitalis, Ne- 
rium, Andromeda, Ledum, Epilobium angu/tt. 
* Linnaus claims the Invention of the Diitinctions 
given in this Chapter, preceding Botanifts not having 
(as he fays) attended to the Foliation in Buds.
