MOORE—ADDENDA TO BRITISH AND IRISH MUSCOLOGY. 191 
that it possibly grew, I think he said, in the county Clare, and I thought 
then that he knew it did, and put you down as the fortunate discoverer. 
However, I heard the other day from Mr. Davies—‘‘I think Mitten’s 
Barbula recurvifolia, found by D. Moore in Ireland (my specimens are 
three inches long), I got at a cascade in the Vallais, Switzerland.” It 
is a splendid plant, always barren, and grows always by cascades. I 
have often searched, expecting it in Britain, but never succeeded in 
finding it. Mitten’s Barbdula recurvifolia is Schimper’s Grimmia 
Gigantea. Schimper’s Barbula recurvifolia is a very different thing. 
I found the latter abundant in Yorkshire; this year barren. You shall 
have the mosses you want as soon as I can get them out of my drying 
paper. 
‘Yours very truly, 
‘‘GrorceE Epwarp Hunt.” 
I have, secondly, to notice a species of Sphagnum new to the Irish 
Flora, and, so far as I am aware of at present, it has not yet been re- 
corded as British—namely, Sphagnum rigidum, var. compactum. In 
general appearance this plant has much resemblance to Sphagnum 
compactum, but differing from it, by the former having the cellular 
utricles well marked with strong spiral strie. It was collected by me, 
without fruit, during the month of December, 1866, in bogs near Kyle- 
more, Connemara. I have examples of the same species, sent by Dr. 
Schimper, who collected them in turfy bogs at the Vosges, France. 
The following are additional habitats for rare species : — 
Bartramia rigida, Bals et Notaris—This rare and pretty little species 
of Bartramia, which hitherto has only been known to grow in one or 
two places of the south-west of Ireland, was collected by me on the 
microscopical excursion party, in good condition, on the 17th of last May, 
growing on wet rocks, between the Wooden-Bridge and Arklow, county 
Wicklow. 
Hypnum Kneiffir, Schimper—Very large and fine, but without fruit, 
in marshy hollows among the sand hills, on the coast of Wicklow, near 
Mizen Head. 
Hypnum elodes, Spruce—The same habitat with the last, but not in 
fruit; May, 1868. 
Oligotrichum hercynicum, De Candolle—This plant, which has only 
been once before collected in Ireland, by Professor Dickie, late of the 
Queen’s College, Belfast, was found in some quantity growing on damp 
clay banks by the roadside, between Wooden-Bridge and Arklow, on 
the microscopical excursion party, on 17th of last May. 
Petalophyllum Ralfsi, Gottsche, Jungermannia Ralfsit, Wilson. Only 
one habitat has hitherto been recorded in Ireland for this rare plant—- 
_ viz., wet hollows among the sand hills on the coast between Malahide 
and Portrane. It has lately been discovered in some quantity growing 
on wet spots near the North Bull, by Mr. D. Orr, who brought plants 
into the Botanic Gardens, which are fruiting at this present time.
