O b s .—This is a very beautiful and distinct species and not
likely to he confounded with any other of the British Hepatic».
By several authorities it has been placed with the Frullania but
Dr. Spruce has kept it distinct, retaining for it Dumortier’s genus
Juhula; in colour, texture and habit it differs from any of tlie
Frullanim and, as Dr. Spruce points out, “ Hep. Am. et An. ”
p. 60, occupies a position intermediate between this genus and
Lejeunea, agreeing with the latter in the bracts of the female
flower being adnate to snbfloral ramuli (or innovations) and other
characters.
The plant was discovered in the South of Ireland by Miss
Hutchins and named after her by Dr. Hooker.
Var. integrifolia, Nees, is a more slender form with antical
lobes less spinose, sometimes, but rarely, entire, postical lobe
evolute; I do not attach much importance to these characters as
plants from different localities vary from type to this form according
to dampness or shade.
The description is taken from Dr. Spruce’s “ Hep. Am. et An.”
where further valuable notes are given.

Plants usually delicate, small, a few very minute, some robust,
creeping amongst mosses or other hepatics, stratified or osespitose
or pendulous, pallid, whitish or yellowish-green, sometimes dark
brown. Stems terete, slender, rarely firm, pinnately branched,
rarely plumaiform or dichotomous, all branches contiguous to
the outer base of the leaves, i.e. infra-axillary. Leaves oblique or
almost longitudinally inserted, alternate, complicato-bilobed,
margin entire, serrulate, denticulate, dentate, spinose or ciliate,
rarely laciniate, antical lobe larger, broad or narrow, incubous,
postical lobe (lobule) usually rbomboidal or ovate, incurved and
ventricose rarely plane; epidermis smooth, papulose muriculate
' rarely echinate. Cells subequal, small or medium in size, sometimes
minute, leptodermous; trigones and angles rarely conspicuous.
Stipules in nearly all species present, in a few wanting
bifid or rarely entire. Inflorescence dioicous or monoicous (very
rarely paroicous). Androeoia on amentiform branches, rarely on
the chief stem; bracts subequal, diandrous, very rarely triandrous
in a few species monandrous. Female flowers monogynous.
Sub-floral innovations where present solitary or binate and
opposite, in most species adnate to the bracts. Bracts ¥ 1 pair,
rarely several, planilobed. Perianth free from the bracts, oval
oblong or pyriform, terete or angular, variously winged, cristate
or ciliate at the angles, leptodermous. Calyptra about half the
length of the perianth, obovate or pyriform, thin. Pedicel cruciate
on the section 4 cells across, quasi-artioulate when dry and mostly
