A lthough th e Dillenian figure (t. 71. f- 19) has be en quoted by almost every w rite r upon
th e sub je c t, as a synonym to this species, y e t i t is c e rta in th a t i t only represents a small
v a rie ty o f J . nemorosa. I t req u ire s, however, to b e rem a rk ed , th a t in th e o rigina l specimen
th e re a re no tra c e s o f any la te ra l fi'uctification, as th e pla te and description would lead us to
imagine. W ith reg a rd to th e o th e r references, which I have been led to re ta in , I r e g r e t to say
th a t i t is by no means in my power to speak w ith th e c e rta in ty I wish. Pollich’s p la n t is very
do u b tfu l, and I suspect th a t both this a u th o r, and L ig h tfo o t, may have confounded J . resupinata
w ith J . undulata. IVeber's description accords well w ith o u r species, except where he remarks
th a t th e leaves a re “ ovata, a cumina ta .” O f th e auricles he ju s tly observes th a t th ey are
“ in sup e rio ii surculorum superficie a lte rnæ , concavæ, foliis non m u ltùm minores, ro tu n d a tæ .”
Leers has done no more th a n copy th e L innæ an cha ra c te r. R o th , as usu a l o rigina l, says th a t
th e species is distinguished by th e auricles b e in g b u t little less th a n th e leaves, which is certainly
t r u e ; b u t he un fo rtu n a te ly gives a second character, q uite th e contra ry, th e la te ra l situ a tio n of
th e calyces, which a re u n doubtedly ten n in a l. Lama rck’s descriptions a re p a rticula rly imperfect
and unsatisfactoiy.
J . resupinata has in many respects a resemblance to J . undulata, b u t is to be distinguished
from i t by its m uch smaller size, its pro cum b en t mode o f growth, and its nearly equal, concave,
conduplicate, b u t n o t closely appressed, lobes. T h e en tire m a rgins o f its leaves, and th e ir figui'e,
will always p rev en t i t from b e in g confounded ir ith / . nemorosa and J. umbrosa. ■/. saxícola,
o f S chrader, a p la n t very ab u n d an t on th e Continent, b u t one which has n o t y e t been detected
in B rita in , apjiroaches th e present, species in color, and in th e division o f th e le a f in to two nearly
equal lobes. Of this p lan t, however, th e le a f is concave, and th e lobes n o t conduplicate, b u t
rema rkably involute and pointed.
I t has be en in ano th e r place observed, th a t th e figure in English Botany named
J . resupinata, belongs t o / . nemorosa: Dr. Smith, like llo th , probably re lying upon Dillenius,
describes tlie fructification o f his species as usually g rom n g from th e side o f th e s tem ; b u t this,
as ta r as I have Iiad th e o pportunity o f rem a rk in g , is always, as above remarked, tc n n in a l,
th o u g h i t is probable th a t i t may occasionally have th e appearance o f b e in g la te ra l, when a
yo u n g shoot origina te s immediately ben e a th it.
T h e male fructification I had no opp o rtu n ity o f seeing, till some tim e a fte r th e plate was
engraved, so th a t i t could n o t th e re be inserted.
