2 y6 Cf Leaves . 
The various methods which nature takes to preferve 
the leaves from the injuries both of the ground and 
weather are, viz,, the young buds of ammi, at their firft 
eruption from the ground, are couched, as fern is rowled 
inward; each bud, againft the brace of the ftalk of the 
foregoing leaves, and raoft exactly inclofed in the mem¬ 
branes thence produced. Nature hath generally provided 
them with another protection, where the ftalks of the 
leaves are fo long that they cannot lap over each other, 
the bottoms of the {talks are expanded into broad mem¬ 
branes, as in crows-foot, doves-foot, clover, cranfhill, 
strawberry, harrow, &c. and fometimes inftead of two 
{kins lapped over each other, one entire {kin is produced 
from the {talk, in which, as within a fecundine, the bud 
is fafely lodged, which it gradually breaks open in its 
growth. 
It is alfo obfervable in dock, forrel, biftort, and all 
other plants of this fort, with this difference, that every 
veil or fecundine is not here produced from the {talk of 
the leaf; whereas in the former every bud hath one to 
itfelf in thefe plants, every leffer leaf, together with its 
own proper veil, is always inclofed with the next greater 
leaf in another common to them both, and both thefe 
with the next in another, and fo on to the greateft. The 
orchis, and other plants of this fort, have a double 
fheath over all. The buds of fome herbs as plantain, 
having no hairs growing over them, are covered with 
hairy thrums, and the nettle hath baftard-leaves or inter- 
foyis between leaf and leaf, for the prefervation of its 
flings. 
Another fort of protection is feen in white archangel, 
and other plants of a like fhape. In which the greater 
leaves do alfo inclofe the lelfer, by a double fore curl 
at the bottom of every two great leaves, which em¬ 
braces
