HEPATICS FROM WEST SUTHERLAND SHIRE 
231 
fragile, the lower leaves brown or blackisli-brown, the upper more or 
less reddish to almost carmine, broadly cordate when battened out, 
larger leaves L mm. and more long and equally broad (smaller leaves of 
the more slender stems 0*7 mm. long and equally broad), subcordate at 
the base, apex broad with a shallow sinus, lobes unequal, roundish. 
Apical cells about 12 /x, lumen stellate, interstices almost equal 
to the lumen (rarely less incrassate and not conspicuously stellate), 
cells of the middle of the leaf similar, but larger, 18-20 /x long, 
14-15 /x broad, basal cells almost rectangular, much larger up to 
43 g long and 17 /x broad, nodulose, incrassate in the angles. 
Indorescence dioicous, $ terminal, often with innovations under¬ 
neath ; involucral leaves slightly larger than those of the stem and 
in other respects similar, but more cordate at the base and the lobes 
unequal, the latter sometimes smaller and subacute, bracteole absent. 
Perianth up to 22 mm. long, 6 mm. broad (often less), cylindrical, 
subtriquetrous above, bleached and plicate-constricted at the mouth, 
the rest reddish-brown, in the upper part formed of elongated, subrect- 
angular almost equally incrassate cells, mouth provided with short 
incurved cilia, often of two superimposed cells. Capsule unknown. 
The Sutherlandshire plant agrees well with the above description 
and with the specimen in Schiffner’s Hep. Eur. Exs. No. 423 so far 
as the very characteristic shape of the leaves is concerned, though as 
pointed out by Mr. Jorgensen it is considerably larger. Mr. Mac vicar, 
who has also kindly examined and compared it, points out that it is 
a good deal larger and darker in colour than Schiffner’s plant above 
referred to, but he sa} r s that there is little difference otherwise, and he 
adds that “ the more concave fragile leaves, only about as long as broad, 
and the usually retuse or emarginate apex with rounded or obtuse 
lobes, seldom subacute, are quite different from those of A. Doni- 
anum .” It is unfortunate that there are no perianths on the Suther¬ 
landshire plant for comparison. The plant was always found on 
Ben Fhurain as a few stems intermixed in tufts of A. Donianum , 
but in Norway it has been found in considerable quantity and 
often in pure tufts.
