J- fp reads out various leaves, of an hard, tough, coriaceous
fubftance, and very different in fize, form, and colour. When
it grows on pocks, in a low,, moift, and ihady fituation, they
are ëxjended töfa confiderâble breadth; the margins lobed,
waved, gaihed in, and fometimes other fmaller ones grow upon
them; and in rainy weather, or when immerled in water, the
iurface is of a ftrong duiky green, the tinder fide of a fulvous
red : In this ftate it is expreffed on the plate at a. When the
plant is dry the green changes to a brownifh aih colour, the
marginal lobes roll backward, but the colour of the under fide
changes not : In this ftate it is figured at c.

air, the leaves are ihoft, thick,, hard, of a duiky olive colour,
numerous, and crowded together;, thus it is feen at b. In all
thefe ftates, the furface is diftinguiihed with numerous very
minute pores,'which,are feen, a little magnified, at d. Thefe
pores are the mouths or outlets of the l'phaerulae, which are
lodged within the fubftance of the leaf. Thefe fphaerulae are
truly globular, of a beautiful gloffy orange coloug; containing
when young a pale coloured gelly. The internal fubftance of
the leaf is of a bright beautiful green. A particle is magnified
