Perigonial scales (f. 2) numerous, crowded, sometimes forming a beautiful fringe on each
side th e nerve (f. 4 ) , a t other times altogether concealing it (f. f. 2. 3 ) ; they are, each of
th em , o f an ovate o r roundish figure (f. 5 ), much laciniated and toothed, concave on th e
underside. Among these scales
The Anthers are dispersed (f. f. 3 . 4 ) , eacli o f them (f. f .5 , 6) roundish-ovate, yellow-
brown. supported upo n a very short white fo o tsta lk .
F em a l e F r u c t if ic a t io n placed always on th e nerve, on th e up p e r surface o f th e frond, and
ge nerally near th e centre.
Cahjx double: th e exterior (f. f. S. 10) th e shorte st, and very much c u t and laciniated a t
th e ma rgin ; its texture nearly resembles th a t o f the frond, o r, i f any th in g , is ra th e r
more de lic a te : the reticulation, too (f. 1 1 ) , is composed o f more oblong areolæ; th e
interior (f. f. 9. 15. 12) is still more delicate (f. 1 4 ), o f a p a le r color, thric e o r four
times the len g th o f the outer one, subcylindrical, a little plicate and toothed a t the
m outh, a t len g th to rn on one side by the b u rstin g forth of the capsule (f. 18).
Germen a t first ovate (f. 1 5 ), tipped with a sh o rt, obtuse style ; afte rwa rds lengthened out,
so as to equal and often exceed the in n e r calyx.
Calyptra (f. 18) cylindrical, o f a ra th e r thick subearnose substance (f. 13), white, with very
m in u te oblong re ticula tions. Ne a r its base are a few abortive p istilla.
Peduncle nearly an inch long, white, succulent, semipellucid, a little flexuose.
Capsule oblongo-ovate, sp littin g into four, o r sometimes only thre e , valves, and these a re not
unfrequently united a t th e ir apices, as is the case with J . Hookeri and some o th e r species.
Color ra th e r a pale brown o r chocolate.
Seeds numerous, minute , sphærical, fulvous. Spiral filaments o f th e same color, very long,
formed o f a double helix, closely twisted.—Whether these a re a ttached, as in J . epiphylla,
to the base o f the capsule, or a t th e extremity, as in J . pinguis and J . fu r c a ta , I am
unable to determine, fo r want o f specimens in a sufficiently good sta te o f preservation.
1 have observed no Gemmæ on any specimens th a t I have yet m e t with.
T o none can this species be with more propriety dedicated th a n to its discoverer, Charles
Lye ll, Esq., a gentleman to whose unwearied researches almost eveiy page of this work bears
unequivocal testimony, and to whom I am happy in being able th u s publicly to express my
g ra titu d e and esteem ; while every one who is acquainted with him, will agree with me in saying,
“ E a me suoi merti
“ E 1’ ingegno non stanco
“ T r a piante e c a rmi e s tu d j, e il cuor s i franco,
“ Costumi o rn a li, e il viver dolce e cheto,
“ Anche son noti."
I t was in th e neighbourhood o f his se a t, Bartley Lodge, in the New Fore st, Hampshire, th a t my
valued frien d first m e t with this highly curious p lan t, which he has since found in boggy places
on his estate a t Kinnordy, in Angusshire. I t grows likewise in Ire land, and I have th e same
species given me by Mr. Dickson, who says i t was gathe red in the E a st Indies. T h e following.
J . hibernica, a lthough so nearly allied lo this, I believe to be perfectly distin c t. I t accords in
g eneral h abit, in tex tu re o t Ihe frond, in Hie double calyx, and in th e male fructification a rising
from beneath th e perigonial scales ; b u t it is removed from it by th e different substance of the
nerve, by th e more d eeply-divided o ute r calyx, by th e shortness o f the C orolla, and by the dilterenlly-
shaped, and distantly-placed, perigonial scales. 1 have received several Jungermanniæ, both from
th e Ea st, and West Indies, which agree in general habit with both these, and which wiU probably
be found to have th e same fructification.
