along with J. calyptrifolia. Fr. March.—A singular little plant, forming
small green tufts,"whose foliage is not distinctly visible to the naked
eye; yet it is larger than in the following species. " A curious var. is
found by Dr. Taylor at Woodlands, near Dublin, incrusting Anomodon
vitieulosum ; its stipules are hardly to be discerned and the perianth is desti-
tute of the winged angles and tubular mouth usually seen in the species."

imperfectly) 2-lobed the upper lobes hemispherical the lower
ones minute almost obsolete, stipules ovato-rotundate bifid,
fruit lateral, perianth obovate-rotundate pentagonal, the mouth

Bark of Holly, Ash and Fir ; as well as on rocks, principally in the
south of England and Ireland : first discovered by C. Lyell, Esq. Near
Dublin, Dr. Taylor. Not rare in Cheshire. Fr. Apr. May.— This well
deserves the name which Sir J. E. Smith has given to it, for it is cer-
tainly the most minute species with which I am acquainted ; its tufts
form small green granulated patches. Mr. Wilson observes that stipules
are seen upon the barren branches only.
71. J. ctlyptrifolia, Hook. (hooded-leaved Jungermannia);
stem creeping branched, leaves unequally 2-lobed, the upper
lobes larger calyptriform the lower ones obtusely quadrate circumvolute,
fruit lateral, perianth oblong depressed and plane at
the apex quinquedentate, the mouth minute contracted, cap-
sule transparent quadrifid. Hook. Br. Jung. t. 43. E. Bot.

On the stems of Ulex nana, near Bantry, Miss Hutchins. Killarney,
W. J. H., whereat Turk Cascade it is more plentiful on Fir-trees than
on Ulex, and always grows in very small detached tufts. Mr- Wilson.
Lowdore, C. Lyell, Esq. Fr. Oct. Nov.—This species is not only
among the most minute, but amongst the most singular in structure of
all the Jungermannia;. Its leaves almost exactly resemble the calyptra
of a moss, and they are remarkably attenuated at the point ; the opening
at the base is almost covered by the circumvolute lesser lobe.
*** Lower or smaller segments (of the leaves saccate.)
72. J. Hutchinsia, Hook. (Miss Hutchins Jungermannia); stem
creeping branched, leaves unequally 2-lobed the upper lobes
ovate spinuloso-serrate the lower ones minute saccate at the
base frequently unidentate, stipules roundish-ovate subserrate
acutely bifid, fruit lateral, perianth obcordate triangular. Hook.

First discovered in the south of Ireland, at GlengarhT near Bantry,
along the banks of the first river, going from Bantry, above the waterfall
; and in gloomy caverns at the side of other mountain rivulets, by
Miss Hutchins. Turk waterfall and other places near Killarney ; Bal-
linhasig Glen, near Cork ;
and in a barren state in the pass of Llanberis
at the foot of Glyder Mountain, N. Wales. Ft. March.— This bcauti-
