O b s .—This is a very distinct species and not likelj' to be confused
with any other, the curiously convolute-oomplicate leaves,
which in the common form are usuall}' bidentate, readily enabling
us to recognise it. A large, more erect form has been found on
tbe Continent, and also at Tyn-y-Groes, North AVales, by Mr.
H o lt; it has leaves usually tridentate, but no other character of
importance has yet been observed.
H a b .—Growing on rotting wood, heaths or rooks, in woods
or shady places. Somewhat rare, very rare in fruit.
