H ab. Bogs in tlie New Fore st, Hampshire, and a t Driimby Airy, a waterfall o n the
Noran, Angusshire. Mr. L y e li— Bogs among Sphagnum latifolium and Hookeria lucens,
ne a r Bantry, Ireland. Miss Hutchins.— From some indifferent specimens, gathered at
T u nbridge High Rock, Mr. Foster’s Habitat, in the “ Tunbridge L is t o f Plants,'' it is,
probably, th e “ New Marchantia,” mentioned in th a t work.— (Bears f ru it in May.)

Rools n ot very numerous, simple, pelluciil, almost colorless, proceeclliig from the nerve on
th e underside o f the jdant.
Frond generally about an inch long, sometimes twice, o r even, though very rarely, three
times (h a t len g th , horizontally appressed to th e e a rth , or to the s

I diameter, and nearly linear
r two la te ra l sh o rt branches (f- 7 ) , o r forked at
th e extrem ity (f. f. 1. 19) ; the ma rgin waved, frequently entire , now and then beset w ith
a few distant, unequally-sized teeth ; in th e centre o f th e frond, and ru nning the whole
len g th o f it, is seen a very distinct nerve, ra th e r prominent on both side s; the interior
substance o f this is ha rd and rigid (f. 4 ), and quite unlike th a t o f th e re st of the p lan t,
of which th e tex tu re is remarkably iliin and delicate, much more so than in J . epiphylla,
and approaching nearer to th a t o f J .fu r c a ta . The reticulation is small, and the areolæ
roundish : the color a pale b ut pleasant green.
Innovations (f. SO) are n ot unfrequent on this plant, arising from the underside o f the nerve,
as in J .fu r ca ta . In these, a t first, nearly th e whole breadth o f th e young shoot is occupied
by th e nerve, b ut they gradually bear a nearer resemblance to the pa rent p lant, become
furnished with roots, and a re dc’lached from the old frond. Sometimes these innovations
arc simple (f. 2 1 ) , sometimes forked or branched, as is represented a t f. 22.
