BOTANY OP KERGUELEN ISLAND. 
2. Jungermannia leucorhiza, MM. in Joum. Linn. Soc. xv. 68. Caulis 
procumbens, radicellis pallidis. Folia laxe inserta, quadrata subrotundave, sinu 
aouto obtusoye bilobata, interdum lobo altero minore ; lobis acutis obtusisve, in- 
ciu’vis ; cellulis rotundatis et ovali-hexagonis areolata. 
Kerguelen. Island, in very small quantity amongst mosses, barren, Moseley. 
Stems less than 1 inch long, with the leaves line wide. Leaves green, tinged 
with brown. 
Incomplete specimens of a species not before noticed in the Antarctic regions, 
but which appears to be near to the European J. ventricosa, Dicks, and to some 
states of J. harhata. 
3. Jungermannia colorata, Lelmi. et Lindenl. 
Christmas Harbour, abundant on the hills, Ilooker, Moseley (with perianths). 
1. Solenostoma Lumilis, Jlooh. f. et Tayl. FI. Antarct. ii. 431, t. 168, 
f. 6. (Jungermannia) ; J. inundata, Flor. Nov. Zealand. 128, t. 93, f. 3. 
Ilab. Christmas Harbour, barren, Ilooker. A few fragments with one perianth, 
Moseley. 
Both S. humilis and J. immdata were originally described as stipulate species, 
no amphigastria have, however, been since found on the specimens. It is probable 
that the figure of the supposed stipule of J. humilis, may have been drawn from a 
fragment of Leioscyplms turgescens. 
Scapania, Lind (ex parte) . Perianthium terminale, locve, a tergo ventreque 
eompressum, ante capsulm emissionem apice decurvum, herbacco-membranaceum, 
ore truncato. Involuori folia 2, libera, caulinis conformia. — Plantm terricoloe. Kami 
crecti asoendentesve, simplicos vel furcati. Folia fere ubique mqualia, bifaria, equi- 
tantia, profundc biloba, laciniis submqualibus apicibus rotundatis vel plus minus 
bifidis, textura e cellulis parvis. Amphigastria nulla. 
This description is that of the Synopsis Ilepaticarum, with slight modification, 
it applies to S. densifolia, vertehralis, and chloroleuca, all so intimately related 
that the possibility of their being forms of one species may be conjectured. These 
diil'er from the chiefly European species which were included in the original idea 
of Scapania, and which are now by right of priority assigned to Martinellia, Gray, 
in having leaves not keeled in the space between the equal lobes, a peculiarity which 
gives the plants a different aspect. The perianth known from a single example on 
(S', vertehralis, is like that found in Martinellia, but is narrowed ujiwards, truncate, 
the mo util bent over and denticulate. 
1. Scapania densifolia. Hook. Muse. Exot. 36 (Jungermannia). 
Kerguelen Island, Moseley. 
The specimens agree with those gathered -by Menzies, and are of the same brown 
colour. The distinction between S. densifolia and its congeners may be thus stated:— 
S. densifolia. Hook., lobis foliorum apice integris rarius emarginatis.' — S. vertehralis, 
Tayl., lobis apice exsectis. — S. chloroleuca. Hook. f. et Tayl., lobis apice bifidis.
