It occurred in large pure patches, distinguished in situ by its 
peculiar blue-green, or verdigris-green colour. | 
In both places the habitat was wet peat, and on the Deepdale 
= Moor the hepatie was partly immersed: “re 
 Drs. Arnell and Persson, of Sweden, and Mr. Macvicar, of So 
Hand, regard it as a notable variety that ought to be described. à 
It differs markedly from other forms of Aantia trichomanis in 
the very deeurrent leaves (giving the stem a winged appearance), 
and in the ovate and deeply-divided stipules. The very flaccid 
habit, long stems, and peculiarly-shaped leaves, in addition to 
the striking blue-green colour are also marked features. propose, 
therefore, to describe the plant as a new variety under the appro- 
priate name of aqualica. “+, 
Kantia trichomanis var. aquatica var. nov. — In large, pure, 
_interlaced tufts of a peculiar blue-green colour. Stems very flaccid, 
much-branched, and long, often attaining 60 mm., or even more. 
Leaves very decurrent, giving à winged appearance to the stem, 
of very irregular shape. Stipules ovate (not rounded heart-shaped 
as in type) and very deeply divided. The beautiful blue-green 
colour, such a marked feature in situ, soon disappears from the 
plant in the dry state. I may mention that Underwood's Kantia 
_ aquatica has been lately shown to be a Lejeunea.

__ Marsupella Pearsoni Schiffn. — This hepatie, named by Schiffner 
_in honour of Mr. Pearson, the author of the great work on the 
_« Hepaticæ of the British Isles », Was first published as a new. 
British species in the April number of the « Journal of Botany » 
for 1903. On reading the account in the Journal, I at once made 
_one of my gatherings in Teesdale to be the new species, and 
Mr, Macvicar says mine is certainly the right plant. In the « Jour- 
_nal of Botany » it is shortly described as follows : — « It resem, 
bles M. emarginata in size and habit, but is readily distinguished Le 
from that species by its shiny leaves, which are round, with the 
sinus broad and shallow, sometimes scarcely apparent ; lobes | 
round or with an apiculus; cells with very strongly thickened ne 
_walls, which give them a guttulate appearance ». Mr. Pearson 
_ mentions that the plant grows on exposed rocks in somewhat 
_Swampy places at about 4.006 foot aittudes 5 70
