TWO NEW YORKSHIRE HEPATICS. 
WM. INGHAM, B.A. 
Lophozia atlantica (Kaal.) Schffn. 
In the Journal of Botany, April 1902, Mr. Symers M. 
Macvicar published a short account of this plant as a new 
British Hepatic. It was gathered at Dirlot, Caithness, August 
8th, 1901, by the Rev. David Lillie of Watten. 
The plant is of about the size of Lophozia gractlis, but it may 
be separated from that by the absence of small-leaved attenuated 
stems, and by the leaves being very concave, also by the pre- 
sence of Amphigastria or Stipules. The leaves are either two- 
lobed or three-lobed. 
I found this plant at Hebden Bridge during the meeting of 
the Yorkshire Naturalists’ Union there on 11th June, 1904. It 
grew in large patches on the blocks of Millstone Grit, and is no 
doubt a characteristic Hepatic of West Yorkshire on that rock. 
If any reader has gathered what is apparently Lophozza gracilis 
on this rock-formation, by re-examination he will probably 
find it is Z. atluntica. The former seems confined to limestone ; 
at least that is my experience. 
The stipules (never found on ZL. graczlis) are well developed 
on the Hebden Bridge specimen. Kaalaas, who described the 
plant, allowed too little weight for this feature, but Dr. Arnell 
has pointed out their presence in Swedish specimens, as an 
important distinction from Z. gracilis. During my examination 
a short time ago of the Hepatics collected by Mr. Waterfall 
of Bristol, Lophosta atlantica turned up, gathered by him on 
roth July, 1886, on Mellbreak Fell, Cumberland, and last year 
Mr. Macvicar found it in v.c. 100, Clyde Isles. 
In Norway it has been recorded near Stavanger, and on the 
Island of Stérdo, and it has been found on the Faroé Isles by 
Herr C. Jensen. 
Its distribution as far as known, is entirely western, hence 
the name adlantica. 
Lophozia badensis (Gottsche) Schffn. (J. acuta a. 
Lindenb.; J. luridula Wils.). 
This Hepatic, which has been much confused with Z. ¢ur- 
binata (Raddi) Steph., and also with small forms of Z. Muellert 
(Nees). Dum, was published as a new British species in the 
Journal of Botany for February 1907. 
The original description of this plant is given in ‘ Musct 
1g07 April 1.
