Has.—lIsland of Lewis, Western Hebrides (Dr. Moore, 1868); Witherslack 
Moss, Westmoreland (Barnes, 1875). Forming very dense tumid hassocks. 
This variety was first found in Kamtschatka by Redowski, 
and fertile specimens quite resembling the Hebridean plant were 
collected in Chiloe by Captain King. 
It is worthy of note that the climate of Lewis appears closely 
to resemble that of some of the Antarctic islands, and I observed 
in the grounds of the castle that the beautiful Zscallonia macrantha 
formed immense bushes, which bloomed profusely. The bare 
moorlands which compose almost the entire island, are dotted over 
with innumerable great cushions of Rhacomitrium lanuginosum 
more hoary than usual, and with these between Stornoway and 
Garynahine occur the great tussocks of our Sphagnum, so large, 
indeed, that they attracted the attention of Dr. Moore while 
driving along the road, and not more than three of these have yet 
been met with. The stems of the moss are much intermixed with 
very fine, branched, brown radicles, and in the plant from Wither- 
slack is a large admixture of Odontoschisma sphagnt, the filiform 
radicles of which are interwoven with the stems of the Sphagnum.

Dioicous ; more or less ochraceous, the stem with four layers 
of cuticular cells. Stem leaves spathulate, rounded and minutely 
fringed at apex. Branch leaves closely imbricated, cymbiform- 
’ concave, cucullate at apex, rounded ovate, broad, their chlorophyl- 
lose cells central, enclosed by the hyaline, and densely and 
minutely papillose where united to them. Perichetial bracts 
oblong, plicate, their cells of two forms; in the lower half the 
central part consists of narrow, empty, pleurenchymatous cells, the 
margins and upper half of porose and fibrose cells.
