66 PROCEEDINGS OF SOCIETIES. 
P. urnigerum grow, and fruit beautifully ; even P. alpinum 
does better than many. The Polytricha have not succeeded 
well. 
Bryex.—Aulacomnium palustre is most desirable for culti- 
vation; it grows freely, and the tall pseudopodia have been 
abundant and very interesting. Leptobryum pyriforme should 
be excluded if possible; it becomes a perfect pest, growing 
everywhere but in its own pot. Bryum: about twenty-four 
species of this genus grow in the case ; the best are B. nutans 
and carneum, both of them very beautiful in fruit. B. alpi- 
num retains its fine crimson colour. B.julaceum and B. Zerit 
both do well, whilst the common B. argenteum has been often 
changed, and is now given up. 8B. roseum has been disturbed 
a good deal, ¢ and 2 specimens having been planted together 
to try if fruit would be produced; but as yet there is no 
appearance of fertility. B. Marrati, B. calophyllum, and 
B. Warneum are not healthy. Mnium: all that have been 
tried do well. 
Merzrsirz.—Meesia uliginosa puts forth sete of prodigious 
length; a rather suspicious circumstance in respect of its 
congener M. longiseta. 
Funariex.—Physcomitrium pyriforme. The fruit in its 
season is so dense that not a leaf can be seen. 
BartramMie®.—Bartramia. All are included except B. 
rigida. The best and most satisfactory mosses for growing 
cultivation. Nothing of the kind can exceed them in beauty 
of colour, growth, and fruit. Catoscopium nigritum is gone. 
SPLACHNEX.—S. ampullaceum and S. sphericum have been 
only lately received ; but Tetraplodon mnioides, on the bones 
of a rabbit, has grown and fruited for two seasons most 
vigorously. 
Fiss1DENTE are gems for cultivation. F. adiantoides is a 
portion of a specimen which has been in cultivation for twenty 
years. <Antitrichia curtipendula is not healthy. 
IsornectE®.—The Pterogonia are weakly. The Jsothecia 
flourish. Climaceum dendroides has been very fine, but now 
droops. Leskea sericea and L. polycarpa are very beautiful. 
L. latebricola and pulvinata are fast disappearing. 
Hypnenz. Of Hypnum sixty species are included. They 
are not easily kept in order on account of their straggling 
habit. The vitality of the plant seems to leave the root and 
the centre, and to reside almost entirely in the extremities. 
If these be cut off, the plant will not throw up fresh shoots 
from the roots, but perishes. In some instances I have 
therefore cut off and planted in fresh and suitable soil the 
extremities of the fronds; and these have made young and
